How to Correctly Place the Grinding Wheel On an Angle Grinder

120 photos of the best materials and their purpose

An angle grinder in the countries of the former USSR is called an angle grinder (angle grinder), which is a power tool for abrasive surface treatment. The working tool in it are abrasive wheels (discs) and all kinds of brushes.

How to Correctly Place the Grinding Wheel On an Angle Grinder

Through the use of a variety of nozzles for angle grinders with this tool, you can perform various actions: cut the material, remove the surface layer of the material (do the cleaning and polishing).

For high-quality and non-hazardous work using angle grinders it is necessary to study all types and characteristics of removable working disks. Having studied these characteristics, you can safely select the disk that is best suited to certain types of work. This article will give a brief overview of disks for angle grinders.

The versatility of angle grinders lies in the fact that it can process any materials in various ways. This is achieved by the release of a wide range of consumables. The most important thing is to make the right drive choice.

Summary of the article:

Characteristics of circles for angle grinders

First of all, it should be said that the disks are classified by size and are of the following diameter: 11.5 12.5 15 18 and 23 cm. The diameter of the inner hole is standard and equal to 22.2 mm. The diameter of the wheel angle grinder depends on the tool used.

When acquiring and using circles, it is necessary to strictly use circles of a strictly defined diameter, designed for a particular model. In no case should you dismantle the protective casing with angle grinders and put on a larger disc.

The disk is designed for a specific speed of operation, it is higher on small angle grinders, so a circle of large diameter can be destroyed and cause serious injuries and injuries, especially without the use of a protective casing.

In addition, circles vary in thickness. A thin circle cuts faster, but has less strength and breaks easier.

According to the type of operations performed, there are the following types of wheels for an angle grinder: detachable, grinding and grinding discs.

Cutting wheels for angle grinder

These circles are the most common disks for angle grinders. They are used for cutting various materials. Depending on the purpose, these discs differ in shape, abrasive used and surface treatment method.

Discs for cutting metal, stone and wood are available. Cutting wheels for metal and stone are the most common and are most often depicted in the photo of circles for an angle grinder. Often outwardly these circles are no different. Therefore, upon purchase, it is necessary to carefully study the marking.

The difference lies in the types of abrasive materials used and the composition of the main circle. For metal, simple abrasives are used; for stone, concrete and similar materials, diamond abrasive disks are used. In addition, discs for concrete and stone can be made entirely of metal, on the side surface of which diamond abrasive is applied.

The type of circle must be indicated on the side surface as text or a picture. The color marking of the discs is also used: blue discs for metal, green discs for concrete.

Abrasive can be applied to stone disks, both segmented and not segmented (with a solid cutting edge or cutting sectors). Non segmented application discs require water cooling. Water is supplied in drops on a disk or in a cut. In addition, the discs differ in the amount of diamond grain used.

The wood cutting blade is a classic metal blade for circular saws. Working with this disk is extremely dangerous, it requires skills in working with angle grinders and caution.

When sawing a tree, the disk may jam in the material, after which the tool will necessarily be torn out of hands, which in turn can lead to extremely dangerous consequences. Such discs should only be used on power tools that have a fixed mount to the table and control levers.

Grinding wheels for angle grinder

For grinders, completely different consumables are available for grinding and polishing surfaces. Such discs can be sponge, cloth, felt or with sandpaper.

Some of these discs need to be used with polishing pastes containing fine abrasive.

Wheels for sharpening and grinding

Such discs are used to strip various planes. The most common are twisted cones, grinding consumables and diamond grinding wheels.

Twisted cone looks like a metal cup with a brush attached to the edges of a metal wire.

The stiffness of the cone directly depends on the thickness of the wire. This tool is best suited for cleaning surfaces from old paint.

Sharpening consumables are a small grinding wheel for mounting on an angle grinder and is designed for rough processing of metal.

Diamond peeling elements are similar in appearance to twisted cone, only metal brushes are not attached to the side surface, but diamond spraying is applied. With such a tool, for example, it is very easy to remove a small area of ​​concrete screed.

Grinding wheels and discs for wood and metal angle grinder

Among the construction tools, the angle grinder stands out for its versatility. Changed the nozzle. and the cutting tool turned into a grinding one. Any kind of work in which it is necessary to use rotational motion is possible. We will deal with the assortment and purpose of one category of nozzles. grinding wheels.

Types of nozzles

diamond wheels for polishing granite

Nozzles for an angle grinder differ in shape, thickness, diameter, material of manufacture and are divided into four groups:

  • detachable;
  • polishing and grinding;
  • for sharpening;
  • peeling nozzles.

The most extensive and widely used group are cutting discs. Most often, consumables are purchased for work on wood, stone, metal, diamond wheels. The diameter of the tool can be from 115 to 230 mm, a thickness of 1. 3.2 mm, the larger the diameter, the thicker the disk. Special abrasives are applied to the cutting surface of the tool on the stone. It is advisable to use wood and metal disks together with a device for stationary installation of an angle grinder, otherwise the operation may cost several fingers. It is preferable to work with fine gear discs.

Diamond cut any materials, are usually used during laying of porcelain tile, tile, reinforced concrete. The edge of the diamond wheel can be torn or solid, and the size of the diamond particles: larger or smaller.

The packaging for each disc contains recommendations for use. Although from a financial point of view it is more profitable to purchase a universal tool, its performance will be lower than that of a specialized one.

Grinding and polishing wheels

Grindings perform the following types of work:

  • grinding;
  • cleaning;
  • peeling;
  • rust removal;
  • polishing.

This is the most numerous group of nozzles, which can be:

  • with replaceable emery wheels;
  • with a spongy surface;
  • felt;
  • tissue.

Most often, working on such wheels requires a grinding paste or liquid with small abrasive particles. Primary grinding of metal is carried out on circles with a low-abrasive surface, finishing. on felt, fabric. Various surfaces of grinding wheels allow you to bring the processed material to any degree of smoothness, whether it is metal or wood. They are so convenient that they are used in car services for polishing car bodies.

The non-abrasive category of grinding wheels includes:

Petal nozzles are designed for wood processing, for example, exfoliating an old coating.

Cup circles are used when working on concrete and stone, less often on metal. A low-power angle grinder will not cope with such a tool and will quickly burn out. Therefore, they are installed only on a powerful angle grinder. In addition, the curved shape allows you to get to hard-to-reach areas. Grinding is done more accurately, as the fixing nut does not protrude.

Sharpening wheels and peeling nozzles

abrasive grinding wheel

This category of circles and nozzles can be divided into three parts:

  • grinding abrasive discs;
  • twisted cones;
  • rough diamond.

Sharpening abrasive are used for sharpening the tool, cleaning the weld points. They are quite thick (from 5 mm), there is a recess on the inner surface. An example is fiber disks, clean the weld place of scale, and remove well the traces of oxidation. Diamond roughing nozzles work only with stone or concrete.

Twisted cones, they are also cord brushes made of metal or wire brushes differ in size and shape, maximum speed. Most often they are used to remove traces of metal oxidation, brushing wood.

Grinding wheel selection

When choosing a wheel for an angle grinder, the following points are important:

  • the diameter of the disc must correspond to the maximum permissible for a particular tool. Otherwise, the consumable may be destroyed due to exceeding the maximum permissible rotation speed. The power of the tool may not be enough to rotate a large circle. When using a large diameter, it is necessary to remove the protective cover, and this is dangerous for the health of the worker;
  • material to be processed: it is desirable to prefer specialized discs to versatile ones, for example, for wood;
  • maximum permitted linear speed: information about it is printed on the packaging or on the side surface of the consumable. The operating mode of the angle grinder is selected depending on this indicator.

Review and testing of the grinding disc, making a felt disc with your own hands:

what are the types, sizes, how to change

Angle grinder (angle grinder), in common people called "angle grinder", is widely used in construction and in everyday life during repair. With its help, you can perform many different technological processes. To choose the right tool to perform a certain type of work, you need to familiarize yourself with what kind of discs and nozzles are for angle grinders. The tool for this device is selected by size and purpose.

Typical Drive Sizes

When choosing a disk for an angle grinder, make sure that the outer diameter of the nozzle does not exceed the maximum allowable values ​​allowed for your angle grinder. For example, if an angle grinder is designed to use a wheel with a maximum diameter of 125 mm, then a 230 mm wheel cannot be installed on it. And there are several explanations for this:

  • the linear speed of the cutting edge will be exceeded, which is fraught with the destruction of the abrasive wheel and causing injury to the user;
  • a small angle grinder does not have enough power to work with a large tool;
  • installation of a nozzle exceeding the permissible dimensions requires removal of the protective cover, and this is already a violation of safety rules.

Disks for angle grinders have standard sizes: 115, 125, 150, 180 and 230 mm. In modern angle grinders landing diameter (the diameter of the shaft on which the tool is mounted) is almost the same and equals 22.2 mm. If you have an “outdated” angle grinder of an outdated model, then you will need to use adapters. rings of different diameters.

All abrasive wheels of any size have special marking, from which you can find out the following information: the diameter of the disk and its thickness, the diameter of the seat, the maximum rotation speed, and also for the processing of what materials it is intended.

Purpose of disks and nozzles

Circles for an angle grinder differ in purpose to:

Cutting discs

The most common task performed with an angle grinder is cutting various materials. The choice of tool material depends on what material will need to be cut.

  1. Metal cutting. A metal cutting disc is made from crystalline alumina from corundum, as well as from synthetic corundum called electrocorundum. The main color of metal cutting wheels is blue.
  2. Cutting stone and concrete. For cutting stone, you should choose a disk from another abrasive material. silicon carbide. This abrasive easily cuts white brick (silicate) and slate. But in order to cut red brick, some types of concrete or ceramic tiles, this circle material will not work. Disks for a stone are issued green color.
  3. Cutting ceramic tiles, red bricks, porcelain tiles and concrete. For these purposes, a diamond disk is already being used.This nozzle is made of metal, an abrasive mass with diamond chips is applied to the cutting edge. The figure above shows a segmented saw blade designed for dry cutting of material. All-metal disks require water cooling during operation.
  • Wood cutting. Although there are wood sawing wheels on the market that are no different from circular saw blades, it is best to refuse to use them for safety reasons. When working with such a tool, the user often suffers severe injuries due to jamming, bouncing, accidental slipping of the tool, etc.
  • Therefore, if you are still going to use a saw blade on a tree, you should adhere to security measures. A protective cover and a handle must be installed on the angle grinder, the user must wear a protective mask or glasses. In addition, you cannot cut materials that are not intended for it with this tool.

    The most safe are disks on wood, at the end of which a chain from a chainsaw is installed. In case of jamming of the tool, the chain remains in place, and the disk rotates idle, which reduces the likelihood of injury to the user.

    Peeling

    If you want to remove a layer of paint or other application, as well as rust from a surface, apply wrinkles. They are disk or in the form of a bowl with a built-in metal wire.

    The wire in these nozzles can be twisted or loose. Its thickness can also be different. The thicker the wire, the rougher the roughing is the grinding wheel or cup-shaped nozzle, and vice versa.

    Grinding

    For grinding and polishing various surfaces (metal, wood, plastic and others), grinding discs and nozzles are used. Often a grinding wheel is used for grinding. petal type. It consists of many “petals” made of sandpaper. The grit of sandpaper can be selected based on the desired type of processing (fine or rough).,

    Also, sandpaper can be attached to the nozzle using Velcro. Such a tool is screwed onto the angle grinder spindle.

    For polishing surfaces, special circles and nozzles are produced that look like pillows made of felt or like disks made of fabric.

    Sharpening

    To sharpen the tool, grinding machines (sharpeners) are usually used. But if you don’t have the latter, but there is an angle grinder, then you can buy a grinding wheel for it, which can be used to sharpen almost any cutting tool.

    The main difference between grinding wheels from cutting wheels is their thickness (at least 5 mm).

    How to change a disk for an angle grinder

    Since the wheels for the angle grinder are consumables, sooner or later they have to be changed. They are mounted on the spindle with a clamping flange (nut) with M14 thread. To unscrew it, in the configuration to the angle grinder there should be a special open-end wrench, having pins on one side.

    So, to replace the tool with an angle grinder, follow these steps.

    1. Disconnect the device by unplugging the plug from the outlet.
    2. Lock the angle grinder spindle with the button located on the front of the housing. When the button is pressed, the stopper enters the hole of the disk installed in the gearbox, which fixes the spindle in a fixed position.
    3. Insert the key pins into the holes on the pressure flange.
    4. While holding the latch with one hand, use the other hand to turn the key to the left (counterclockwise) until the nut comes loose. Then it can be unscrewed without a key and removed from the shaft.In this case, the angle grinder spindle rotates clockwise. But in which direction to unscrew the nut, if your device rotates the shaft counterclockwise? Remember: the clamping flange should always be unscrewed in the opposite direction to the shaft rotation.
    5. Now you can change the tool by first removing the old one.If you notice that dirt has accumulated inside the casing, remove the bottom flange and remove dirt from all surfaces with a steel brush.
  • Screw the flange onto the shaft by hand. The nut should be tightened until you can no longer turn it without a key. After that, holding the stopper, tighten this nut with a wrench, but no more than a quarter of a turn, otherwise the disk will begin to deform.
  • After carrying out the above steps, replacing the tool is considered to be completed.

    Methods of unwinding, if the disk is jammed

    What to do if the pressure flange is jammed? This nuisance, when bitten by a nut, often occurs if the tool is stuck in the workpiece when working with thick and strong materials. At the same time, the abrasive wheel often breaks, and the spindle that continues to rotate tightly tightens the clamping flange. To unwind the angle grinder, if the disk is clamped, there are several ways.

    With a gas key

    This method is considered not quite safe, since it is possible to break the stopper, although in most cases, it is possible to unscrew the nut. In order not to break the spindle lock, do not apply excessive force to the gas wrench. The design of the lock is designed for the force exerted by the standard key.

    To over-tighten the flange, use 2 gas keys. To do this, break off the sticking ends of the abrasive wheel with pliers so that you can get the first gas key to the lower flange. Next, hold both flanges with wrenches and turn them in opposite directions (taking into account which thread on the spindle is right or left).

    Gearbox disassembly

    In case the lock is broken, to remove the tool from the angle grinder, you will have to disassemble the gearbox. Break off the edges of the remaining abrasive wheel with pliers so that you can get to the bolts holding the gearbox cover. After that, unscrew the fasteners and open the gearbox. The cover is removed with the pinion shaft. Further, this shaft should be clamped in a vice, having previously laid aluminum gaskets between the steel jaws, and using a gas wrench, unscrew the flange (do not forget to determine the direction of unscrewing).

    Nut heating

    The nut can be heated using a gas burner, building hair dryer or blowtorch. The heated flange is usually obtained by unscrewing with a standard key for an angle grinder.

    Stitching a circle

    If after applying the first 3 methods the nut does not loosen, then the remaining abrasive wheel between the flanges can be grinded. To do this, do the following.

    1. Use a pair of pliers to remove the rest of the circle along the edges of the nut.
    2. Squeeze a piece of sheet iron in a vise as thick as the disc itself, turn on the angle grinder and grind the rest of the circle onto the end of the sheet iron.

    Instead of iron, a piece of abrasive wheel can be clamped in a vice. In this case, the grinding of tool residues between the flanges will occur faster, and the nut can be unscrewed by hand.

    But the use of a stationary abrasive wheel requires great accuracy, because when grinding the remains of the tool, the geometry of the flange can be damaged. If this happens, you will have to cut the nut.

    Using penetration grease

    Water the joint between the flange and the shaft. liquid WD-40. It has the property of penetrating into inter-threaded spaces and small gaps. After applying the fluid, wait about 5 minutes and try unscrewing the fasteners with a standard wrench.

    Using a hammer drill

    Some owners of grinders in a situation when the clamping nut is jammed, install a nozzle in the punch “chisel "or" jackhammer”, Insert it into the hole of the flange at an angle and turn on the jackhammer without rotation. Accordingly, the stopper button must be pressed. All that is needed is a couple of light pressing with a puncher (so as not to break the shaft lock), and the nut will begin to turn.

    Cut the pressure flange with a hacksaw

    This method can be called radical, because you have to buy new fasteners, and it is used if the nut is not unscrewed by any other methods. To saw the flange, hold down the stop button so that the shaft does not rotate and, applying hacksaw, cut the fixing nut.

    Nozzles

    Photo of grinding wheel for angle grinder

    For an angle grinder or an angle grinder (angle grinder) there are different nozzles that differ in shape, size, thickness, diameter, materials. All of them are divided into four groups:

    • Cutting;
    • Polishing, grinding;
    • Sharpening;
    • Peeling.

    Cutting-off wheels are the most popular disks that an angle grinder is equipped with. They allow you to cut material, work on metal, wood, concrete, plastic, etc.

    But our main task is to study grinding and polishing devices. Also noteworthy is the circle, which belongs to the category of peeling and grinding tools for angle grinders.

    When buying circles, pay attention to the packaging in which the circle is sold. It presents all the main recommendations for use. The surface of the disc itself provides information on the purpose, size, abrasive material, and other product specifics.

    Grinding and polishing

    Photo of grinding wheel for angle grinder

    Grinding and polishing abrasive wheels are designed to perform the following tasks:

    • Grinding surfaces;
    • Scraping parts;
    • Peeling blanks;
    • Rust removal from the surface;
    • Polishing products.

    The largest group of circles with which the angle grinder is equipped is precisely grinding. They can be designed to work on wood, concrete, metal, stone. The following types of grinding components for grinders are distinguished:

    • Interchangeable emery wheels
    • Products with spongy surfaces;
    • Felt;
    • Fabric.

    The grinding wheel has several nuances of using an angle grinder during operation.

    1. The polishing and grinding process carried out using an angle grinder usually involves the use of a special grinding paste or liquid with the addition of fine abrasive particles.
    2. For primary grinding on metal, circles with low abrasion surfaces are used.
    3. Finishing is carried out with felt and fabric nozzles angle grinder.
    4. Due to the variety of surfaces, abrasive wheels bring the product to the required level of smoothness.
    5. Depending on the specifics, grinding wheels are used when working on wood, concrete, metal, plastic, etc.
    6. Grinding and polishing products are widely used in car services. With their help, polishing of a car body is easily and effectively carried out.
    Non-abrasive grinding

    The angle grinder can be equipped with wheels with abrasive components and non-abrasive products. The latter are of several types. The most popular of them are:

    • Cup nozzle angle grinder. They are used when working on concrete and stone, but can process metal. It is impossible to equip a low-power angle grinder with a cup nozzle, since it requires increased power. Otherwise, the angle grinder simply burns out. Due to the curved shape, cup nozzles can handle hard-to-reach areas;
    • Petal. This nozzle is designed for woodwork. Perfectly copes with the task of removing peeling coatings.

    Sharpening and peeling wheels

    A circle designed for grinding and peeling work on wood, concrete, metal, is divided into three types.

    1. Grinding grinding wheel for angle grinders. The grinding wheel type is used for sharpening various types of tools, cleaning places where welding events were held. Such a circle has a sufficiently large thickness. at least 5 millimeters. On its inner surface there is a special recess
    2. Diamond grinding wheel. This peeling disc allows you to process concrete and stone. The circle can be called highly specialized, because it allows you to work only on stone, concrete.
    3. Twisted cone. This circle is also called cord brushes. A peeling disc of this type is made of metal, characterized by multiple wires that form a brush. Peeling cord brushes distinguish by length, shape, size and maximum speed. Such nozzles allow you to work on wood when brushing, as well as remove traces of oxidized metal.

    Selection recommendations

    When choosing nozzles, you should adhere to certain recommendations. They will allow you to purchase the nozzle that is optimal in terms of characteristics, capabilities and specifications, with which you will equip your angle grinder.

    There are three most relevant tips that will be useful for beginners and experienced enough specialists in working with angle grinders.

    1. Landing diameter. Each disc has a specific standardized bore diameter. Similarly, the angle grinder itself is characterized by the presence of a strictly fixed diameter for landing the disc. Compare these values ​​to find the right size nozzles. Otherwise, they simply won’t fit on your angle grinder.
    2. Outside diameter. Discs have restrictions on the outer diameter for each particular model of an angle grinder. Learn the specifics of the tool, compare with the parameters of the selected disk. No nozzles that exceed the maximum allowable angle grinder values ​​can be selected. Otherwise, the product will simply collapse, not having time to really begin its work.
    3. Power. The diameter of the disc and the power of the angle grinder are two parameters directly related to each other. The higher the power, the larger the nozzle will be able to effectively rotate the angle grinder motor. Low-power models are not able to cope with the requirements of large nozzles, because their joint work does not bring the desired result, the disc is stuck in the surface of the processed material.
    4. Processing material. All nozzles on the market are divided into specialized and universal. It seems to many that the purchase of a universal product is more profitable, because with a single nozzle you can perform a wide range of operations for processing wood, metal, plastic, glass, polymers, concrete, etc. In practice, the quality indicators and overall performance of universal nozzles are inferior to specialized ones. For rough homework, you can use a universal product. But the best solution would be to buy several specialized nozzles. for wood, metal, concrete, stone, etc.
    5. Maximum linear speed. To find out this parameter of the nozzle, just look at the product packaging or on the side surface of the components. Based on the information received regarding the maximum permissible linear speed, you will need to select the appropriate operating mode of the angle grinder.

    When working with angle grinders, do not forget to observe basic safety rules. If necessary, you can always improve the design of the angle grinder, making it a full-fledged stationary machine, and equip it with auxiliary devices. The functionality of angle grinders is huge. It is only necessary to correctly implement them.

    What are the discs for angle grinder? Classification, Overview

    Angle grinder (angle grinder, angle grinder). a tool with which several types of work can be performed. In each case, the use of additional devices is required. special discs and nozzles. Which circle to choose in a particular case?

    The sizes of disks intended for the angular grinder can be different. Each of them has certain diameters. internal and external. The inner one is linked to the landing size of the angle grinder. In household grinders, it is the same. 22.2 mm. The cutting depth or the surface area to be ground depends on the outer diameter of the circle. A larger disc gives a deeper cut. The diameters of the external disks for the angle grinder: 115, 125, 150, 180, 230. The circles have different thicknesses. When choosing, you need to give preference to those that are thicker. The thin disk will wear out faster.

    Types of drives

    What are the discs for angle grinder? Circles to an angle grinder are classified by the following parameters:

    • type of work;
    • material of which the circle is made;
    • the form;
    • sizes.

    There are special circles. on wood, metal, concrete, artificial and natural stone, etc. About what material the nozzle is suitable for, says marking. Each type can be suitable for several types of machined surfaces. For example, a stone disc for an angle grinder cuts concrete, brick, ceramics, paving slabs, etc. But it is impossible to cut or grind metal around a tree or a stainless steel nozzle on mild steel. The angle grinder is processed, including asphalt, plastic, glass, fiberglass. If necessary, you can find special disks for an angle grinder (angle grinder) for ceramic granite, granite, reinforced concrete, marble, ceramics, tile, brick, plastic. If you want to save money, it is preferable to look for a universal circle that processes several types of materials at once.

    Classification by type of work

    By the type of work performed, circles for angle grinders are:

    1. Cutting off. They are intended for making cuts, rough cuts, etc. The cutting disc has a cutting edge, which is a solid circle or divided into segments.
    2. Saw. The cutting edge has teeth. An angle grinder is used to trim many types of wood products and their substitutes. To do the job, you need a saw blade. This variety of circles is designed to make an even, clean cut of a massive board, plywood, parquet, drywall. It is also suitable for laminate, fiberboard, particleboard (including laminated), as well as sampling grooves in gas silicate.
    3. Peeling (grinding wheels). Such nozzles remove the old layer of paint, varnish, primer from the treated surface, carry out grinding.
    4. Cleanup. This is a kind of peeling. These include disk metal brushes. They can remove rust and other stubborn dirt.
    5. Petal circles. They are also referred to as sweeping. The petal circle is used in the processing of metal, wood, plastic products, stripping welds and burrs, removing rust, etc. The petal disk for an angle grinder consists of plates fixed with an overlap around the circumference, according to the principle of flower petals. Varieties: end, batch, with mandrel. The petal end circle on the angle grinder is designed to be machined at an angle or the usual flat. There are two of its subspecies. straight and conical. A direct flap disc is needed when grinding over a large area. The flap circle is suitable for finishing joints, joints, etc. The flap disk (folded) is also suitable for work on a large area. Cleaning wheels with a mandrel for an angle grinder are used when working with cavities. They help to achieve the highest precision machining.
    6. For cutting seams. They are used when making joints in concrete, asphalt, etc. With such nozzles, the grinder is also suitable for this work.
    7. Polishers. Such circles are used for the final polishing of surfaces. These include polishing removable felt and felt nozzles for an angle grinder with Velcro, as well as an emery wheel.

    Material classification

    Discs for angle grinders are made from several different materials. Each of them has its own characteristics. Types of wheels for angle grinders:

    1. Diamond. They are made of steel, on which diamond spraying is applied. This type of nozzle cuts and polishes any metal, concrete, artificial and natural stone (including granite and marble), ceramics, glass. Saw diamond blade for angle grinder provides the thinnest cut. You need to cut with small cuts. A new variety of diamond nozzles. flexible polishing wheels (“turtles”). Their surface has a corrugated structure in the form of a tortoise shell (hence the name). Flexible diamond blades are mounted on the base. a nozzle made of hard rubber with Velcro.
    2. Carbide. Circles of this kind are also made of metal. They have solder from the edges of high-carbon molybdenum steels with the addition of chromium and nickel. They are used mainly for cutting metals, less often for wood. angle grinder is suitable for working with many metals. There are carbide wheels specifically designed for thin, high carbon, stainless steel, aluminum.
    3. Abrasive. The basis is thick waterproof latex paper with a reinforcing mesh or fiber. A layer of abrasive material is applied to it. particles of aluminum oxide, silicon carbide, tungsten carbide or corundum. The bond for the abrasive is resin or polymer. Grinding fiber disc on an angle grinder is used complete with a support plate made of plastic or rubber. It serves as a stop and cools the abrasive. Abrasive wheels are used as cutting, grinding or peeling. Fiber circle is suitable for woodwork and concrete, processing non-ferrous and ferrous metals. Abrasive is zirconate or alumina, ceramic grain. The fiber circle is ideal for rough removal of old paint from walls, facades and other surfaces.
    4. Scrap metal wire. Disc brushes made of this material are used to remove rust and other types of resistant plaque.

    The disks for an angle grinder can conditionally include support plates. They are also called supporting or disk disks. Plates are made of plastic or rubber. They are used in combination with some grinding, polishing, grinding abrasive nozzles, emery wheels. The need to use a support disk needs to be clarified when buying a particular circle for angle grinders.

    Extra options

    At grinding disks of grinders an important role is played by granularity. The higher its value, the smaller the size of the abrasive particles, and therefore, finer grinding:

    • 40–80. preliminary processing;
    • 100–120. alignment;
    • 180–240. final grinding.

    Granularity of diamond polishing wheels on a flexible basis: 50, 100, 200, 400, 600, 800, 1000, 1500, 2000 and 3000 (the smallest grain). About graininess says marking on the back.

    Cutting diamond blades come in four types:

    1. Solid ("Crown"). They are designed to perform wet cutting only. The cutting edge is continuous. This type of circles provides faster work, makes even cuts without chips.
    2. Segmented. Segmented disks have uniformly located slots on the cutting edge directed towards the center. They divide the disk into equal parts. segments. Segmented circles are used when making dry cuts.
    3. Combined (“Turbo”). The edge of the disk has a serrated shape, consisting of inclined grooves. This type of disc is universal, suitable for dry and wet cuts.
    4. Turbo-segmented. Their edge is also serrated, but divided into segments, like a segmented disk. Suitable for dry cutting. A special shape improves productivity.

    During cutting, the angle grinder of many types of materials (concrete, ceramics, etc.) produces a large amount of dust. It is advisable to avoid harmful consequences for the person performing the work, as well as dust settling on the surrounding objects. Therefore, the wet cut technique is used. During operation, make sure that the cutting edge is moistened with water, then there is less dust.

    On sale you can find circles for angle grinders with a flange. The flange reliably and quickly fastens the circle, increases rigidity, reduces vibration, improves machining accuracy, expands the capabilities of the tool, allows you to process "dead zones", flat corners.

    Conclusion

    A huge selection of wheels for various purposes to the angle grinder allows you to perform many tasks with this tool. From the range of products offered by manufacturers, you only need to select the appropriate disk diameter, material, shape. It should be remembered that a high cost is associated with a higher strength of the circle, and therefore, an increase in the life of the tool is sometimes several times.

    What are the discs for angle grinder? Which circle to cut? Which side to set?

    Choosing a disk for an angle grinder (angle grinder), first of all, you must adhere to the diameter set for a particular model.

    In the article we will talk about:

    And this is really a very important point, because often, in order to increase the depth of cut or the area of ​​the surface to be treated, some “craftsmen" remove the protective cover and establish a circle of superior size.

    Firstly, because of this, the tool itself fails much faster (the gearbox breaks), and secondly, quite serious injuries occur. The fact is that each disk for an angle grinder has restrictions on maximum revolutions or, in other words, on rotation speed.

    The wider the diameter of the circle, the faster the revolutions should be. That is why large disks at high speeds very often simply rupture, and given the fact that there is no protective casing, the consequences can be most dire.

    What are the discs for angle grinder in diameter

    In total there are 5 main modifications:

    The most popular are the angle grinder, and, accordingly, discs ∅ 125 and 230 mm. In everyday life, small models are most often used, while in professional work a more powerful and productive tool is used.

    How to choose a disk for an angle grinder for working with various materials

    The versatility of an angle grinder lies in the fact that it can not only cut almost any materials, but also grind all kinds of surfaces or sharpen a tool. The main thing is to choose the right drive. So what kind of discs are there for an angle grinder? The main groups are as follows:

    • detachable
    • cleaning (grinding)
    • grinding (peeling)

    In turn, in each group there are several varieties. Cutting discs are abrasive, diamond and wood. The former, as a rule, are designed for cutting metal, although there are abrasive wheels on concrete.

    They differ in the components used in the production, and the buyer can distinguish them by color on the information sticker (for metal. blue, for concrete. green), by the inscription (metal. "Steel", concrete. "Concrete") or a schematic representation of a particular material.

    Diamond cutting wheels are designed exclusively for stone, concrete or ceramic products. The most common question that arises among home masters is which disc to cut a tile angle grinder with. In general, circles with continuous spraying without segmentation, grooves and slots are recommended for these purposes, since they leave a minimum of chips on the enamel.

    However, they are used in conjunction with water cooling, that is, on special electric tile cutters with a continuous supply of water. For domestic purposes, you can use segmented disks, which are also suitable for red and silicate bricks, pavers, concrete, paving slabs, etc. It is not recommended to work continuously with any diamond wheels for more than 2 minutes, because, despite the cooling grooves, cuts and grooves around the entire circumference, they dry very quickly when dry cut.

    Another common question, how to cut a thick rubber or car tire? An angle grinder can also perform this operation, for example, with a diamond blade. But you need to do this in the open air, since when heated, rubber emits a pungent smell and can even smoke.

    You need to be very careful in the case of tires, as in the middle of the ramp there is a metal court. Its diamond, of course, will cut it, but at the same time small particles of metal can bounce off. In addition, rubber very often clamps the disc, so you need to unclench the edges during the cutting process.

    For cutting wood, there are special saw blades. This is the most dangerous type of circle, because even with the slightest contact with hands or fingers, they leave serious injuries. They are recommended to be used only under condition of stationary mounting of an angle grinder to a workbench.

    If this is not possible, you need to work as carefully as possible, in no case do not remove the protective cover, do not press on the tool, do not make any sudden movements, be sure to wear a mask and tightly fitting fingers of the signet. It is better to choose disks for an angular grinder for a tree with a small tooth, since such circles are less likely to provoke a back strike effect.

    What are grinding and grinding wheels for angle grinder?

    There are two types of grinding abrasive discs: flat and cup-shaped. In the first case, circles practically do not differ from edged analogues. The difference lies only in their thickness, which is at least 5 mm or more.

    Cup-shaped varieties are more convenient to use, as they allow you to cover more of the treated surface in one pass. Use such disks for an angle grinder in order to clean the welds or sharpen the cutting tool.

    There are four types of grinding or grinding wheels:

    1. Petal (emery) disks for an angle grinder are mainly used when removing old paint or varnish, polishing wooden surfaces.
    2. In order to clean the surface from persistent contamination or rust, special wire nozzles are used.
    3. For polishing the stone, diamond bowl-shaped modifications are intended.
    4. For polishing metal, dish-shaped nozzles made of rubber or plastic are ideally suited to which a removable emery pad or abrasive mesh is attached.

    Which side to put the disc on the angle grinder?

    This question is easiest to answer. A flat circle is marked outward. Cup-shaped modifications can only be set in a single position, so an error is excluded here.

    By the way, professionals say that it makes no difference which side to put the disc on the angle grinder. Their conviction is based on the fact that in circles, even professional ones, there is no arrow pointer in which direction the rotation should take place. Therefore, the installation can be carried out by either side.

    Disks and nozzles for an angle grinder: their varieties and purpose

    Contents: Cutting discs for angle grinder Grinding and polishing discs for angle grinder Disks for sharpening tools and peeling nozzles for angle grinder

    You must admit that it is always more convenient to have one universal tool on hand than several specialized ones. the issue of transporting a huge amount of rarely used "trash" is immediately solved. Instead of carrying a lot of various tools, the craftsmen carry a small set of them. The most universal tool in this regard can be called an angle grinder. With its help, using different discs or nozzles, you can carry out a fairly wide range of various operations. An angle grinder is capable of cutting virtually any material, regardless of its strength, grinding, polishing, grinding, peeling. in general, performing all types of work for which rotational movements can be applied. It is about such nozzles that will be discussed in this article, in which, together with the stroisovety.org website, we will study all the available disks for an angle grinder and figure out their purpose.

    How to choose discs and attachments for an angle grinder

    Cutting discs for angle grinder

    Cutting discs are the most common interchangeable cutting tool for an angle grinder. there are many of them and they are able to overcome almost any material. The most used among them are discs for angle grinders for metal, stone, wood and diamond wheel.

    • Disc for cutting metal. It should be understood that the cutting discs for the angle grinder may differ in their outer diameter and thickness. With the diameter of such nozzles, everything seems to be clear. in this respect they are intended for small, medium and large tools. Accordingly, their diameter can be 115, 125, 150, 180 and 230 mm. As for the thickness of these discs, it can vary from 1mm to 3.2mm. Disks of large diameters are made thicker, disks of small diameters can be of any thickness. This approach to business is associated both with the speed of rotation of the disk, and with the estimated loads on them.

    Disc for angle grinder for metal

      Disks on a stone. They differ from their metal-cutting counterparts in exclusively used abrasives.

  • Wood discs. In principle, the use of such discs is fraught with unpleasant consequences in the form of all kinds of injuries. you need to work with them very carefully. Observance of safety measures during the work with such replaceable nozzles is in your interests. Firstly, it is not necessary to remove the protective cover from the tool and, secondly, for an angle grinder it is better to use a wood disk with a small tooth. In no case should you cut wood with a strong feed. And the use of such nozzles on a large instrument is better to refuse altogether. An ideal application of such a tool would be to use it in conjunction with special equipment (a fixture for stationary mounting an angle grinder).
  • Wood disks for angle grinder photo

    • Diamond blade for angle grinder. This nozzle can be called universal. it is able to cut almost any material, from soft to durable. The most widespread such nozzles were in the field of cutting granite, reinforced concrete, artificial and natural stone and tile. For each of these materials, there are separate varieties of discs. some of them have a solid cutting edge, and some are torn with slots. Also, depending on the purpose of these circles, they may have a large or small fraction of diamond spraying. For example, disks for a concrete angle grinder have fine spraying and special transverse recesses along their entire diameter. In contrast, the diamond blade for stone angle grinder has a solid cutting edge.

    Visually, the purpose of diamond discs is difficult to determine, therefore, when purchasing such nozzles, carefully read the packaging. everything is written in detail about its purpose.

    Grinding and polishing discs for angle grinder

    There are a lot of varieties of grinding and polishing wheels. depending on the required surface quality, disks with removable emery paper, felt, sponge, and even cloth can be installed on an angle grinder.

    Most of them require special fine abrasive pastes or even liquids to work. For coarse grinding and grinding, finely abrasive grinding wheels are used. Grinding discs for an angle grinder allow you to bring almost any materials to the necessary roughness. such nozzles are used even in auto repair shops to polish automobile bodies.

    Flap disc for angle grinder

    Disks for sharpening tools and peeling nozzles for angle grinder

    Among this type of fixtures, in order to expand the functionality of an angle grinder, three types stand out significantly. twisted cones, abrasive grinding wheels and diamond grinding machines.

    • Twisted cones are used for peeling metal and stone surfaces. if we are talking about removing old paint or thoroughly dried cement mortar, then the best replacement tool can hardly be found. It is made in the form of steel cups, wire brushes are installed around the perimeter of which. The size of the wire can be different. depending on the roughness of the processing, the cone can be equipped with both thick and thin wire.

    • Abrasive grinding wheels. Such nozzles are designed for rough processing of metal. with their help they clean welds and sharpen all kinds of cutting tools. As a rule, such nozzles are most widely used on small angle grinders. this is due to ease of use. Such a nozzle can be distinguished from cutting wheels in thickness and shape. their inner part has a recess, which allows the grinding process to be carried out with the flat part of the wheel, and the thickness cannot be less than 5 mm.

    • Diamond grinding wheels. In principle, they are somewhat similar to abrasive tool-grinding. Only in contrast to them, processing with a diamond tool of this type can be performed only by the periphery of the disk on which the cutting edges are placed. In contrast to its sharpening counterpart, peeling diamond is not designed to work with metals, its ridge is the peeling of concrete, stone and the like. If we are talking about removing a small area of ​​cement screed, then come up with something better than this diamond will not work.

    Disks for a photo angle grinder

    In general, one way or another, and disks for an angle grinder can significantly increase the functionality of an angle grinder. In modern construction and other areas of life, it is very difficult to find any industry where an angle grinder is not used. together with a huge number of various nozzles, it is truly a universal tool.

    Nozzles for the angular grinder. Types and features. Application

    With the competent use of an angle grinder, this device becomes a universal tool that can be processed with any material. In this case, the correct selection of nozzles is the main factor.

    Using an angle grinder, you can perform many different operations using different discs and nozzles: peel, grind, polish, and also perform other types of work where you can use the rotary movement of the tool.

    Types of nozzles

    There are many different accessories and attachments used when working with an angle grinder. Consider their main types, design features and application.

    Cutting discs

    These are the most common nozzles, of which many types are produced. Using them you can process any material. The most popular of them were discs for metal, stone, wood.

      Metal cutting discs vary in diameter and thickness. By diameter in the distribution network you can find discs with a diameter of 115. 230 mm. The thickness of the discs ranges from 1 to 3.2 mm, depending on the diameter. These dimensions also depend on the speed of rotation and the load applied to them.

    • Disks for stone processing differ from other types only in the abrasive materials from which they are made. Other parameters are similar.
    • Wood discs. The use of such discs is very dangerous, if you work sloppy, you can get injured. Such discs are essentially saws. Do not remove the protective cover from the angle grinder. It is better to use a wood saw blade with a fine tooth, and not use a large feed. The best option for using such a nozzle for an angle grinder is the use of special devices for stationary fixing an angle grinder.
    • The diamond blade is universal, as it can cut any material. Such nozzles were very popular in the cutting of tiles, stone, concrete and granite. For each material, you can choose your own type of disk. Some models have a cutting edge with slots, while others are solid, and they also come with small or large diamond spraying, depending on the purpose. For example, disks for cutting stone are solid, and for cutting concrete with transverse slots and fine spraying.

    In appearance, it is difficult to determine what the drive is intended for, so when buying, you need to familiarize yourself with the characteristics of the drive indicated on the package.

    Polishing and grinding

    There are many types of circles. They can be cloth, spongy, felt and with a removable sandpaper.

    To work with them, it is necessary to use special pastes with a small abrasive, as well as various liquids. For grinding and coarse grinding, finely abrasive wheels are used. The use of grinding discs makes it possible to bring the surface of any material to the desired roughness. Such nozzles for an angle grinder are used to polish a car body.

    Peeling and grinding nozzles for angle grinder
    These discs can be divided into the following types:
    1. Twisted cones.
    2. Sharpening abrasive.
    3. Rough diamond.
    • Twisted cones are used to peel stone and metal surfaces when removing old cement mortar or dried paint. The cone consists of two steel cups. Along their perimeter are steel wire brushes. Depending on the type of processing, the wire may have a different diameter.
    • Sharpening discs are used for sharpening the cutting tool, stripping welds. Most often, such nozzles are used on low-power angle grinders, since they are more convenient to work with such disks. Sharpening discs differ from cutting models in shape and thickness. In the middle part of the disk there is a recess that allows sharpening with the flat surface of the disk. Its thickness is usually not less than 5 mm.
    • Rough diamond blades are similar in design to grinding wheels. The difference is that the diamond disc works only with its peripheral part, on which there are cutting edges. And also the diamond peeling disc is not suitable for metal processing. It serves for peeling of stone, concrete and other similar materials. For peeling a hardened cement mortar, a diamond disk will do just fine.

    Nozzles for the angle grinder greatly increase the functionality of the grinder. angle grinders are widely used in construction and many other areas. And together with various nozzles they become universal equipment.

    Nozzles for polishing wood

    The grinder can be used to polish a wooden surface, cut trees. For this, special types of nozzles are used for certain types of work. Before you start surface treatment, you must mark it.

    After grinding, circles from the disk remain on the surface. This is noticeable after coating the surface with varnish or paint. This is a feature of the work of an angle grinder. Therefore, it is additionally necessary to walk on the surface with a sandpaper manually. You need to work on wood with an angle grinder carefully, without making great efforts, do not use thin circles, properly fasten them.

    To make the right choice of nozzles for an angle grinder, we consider their specifics of use and various modifications.

    Coarse tools

    Two types of nozzles fall into this category.

    A planer disc can completely replace a manual planer.

    To perform rough processing of logs during the construction of a house, processing posts for fencing, such a nozzle will be an indispensable tool.

    Features of its use are:
    • Only use with a grinder equipped with a second additional handle. For safety reasons, the angle grinder must be held with only two hands.
    • It is allowed to remove the protective cover, as the body of the nozzle is solid, and the probability of its destruction is very small. However, protection from flying chips is required: mittens, glasses, clothes.
    The peeling disc is designed to remove tree bark and rough processing of the workpiece.

    If you have certain skills in the tree array with such a disk, you can select. When erecting a log house from logs, a grinding machine with a peeling nozzle is a good alternative to a conventional ax.

    You can also saw a board with a peeling disc, but the width of the cut will be large and more sawdust will form.

    Nozzles for milling

    There are two types of nozzles: discs and milling cutters.

    Disks are made in different designs. Their difference is the grain size of the abrasive material.

    Such abrasive disks are similar to the surface structure of a manual rasp, with a difference in processing speed. In the presence of dexterity and acquired skills, such discs are used for finishing wood processing.

    Wood cutters are available in a large assortment. They differ in the size, arrangement and shape of the teeth.
    Milling cutters are intended for:
    • Samples of various grooves.
    • Cutting the bowls.
    • Rough edge alignment.
    • Sawing of small pieces of wood.
    Features of use of mills:
    • It is forbidden to remove the protective cover when working with a mill.
    • It is allowed to use the cutter only for the work specified in the instructions for it, with the recommended rotation speed, and other instructions.
    Grinding tips

    The main purpose of the angle grinder is initially grinding, as evidenced by its correct name. angle grinder. Therefore, grinding wood, as an operation, is suitable for an angle grinder as well as possible. Consider the main nozzles for an angle grinder, with which the grinding of wood is performed.

    Cord brushes are mainly used for primary polishing of wood, when it is necessary to even out surface irregularities.

    The name of the end discs indicates their purpose. They process the ends of wooden parts. Face discs are especially suitable for machining corner cuts.

    Petal nozzles are used in a certain sequence of processing operations. Therefore, they need to have several pieces, a separate nozzle for each operation. Grinding begins with a coarse disk, then the size of the abrasive decreases, and nozzles with a finer grain of the abrasive are installed.

    Grinding wheels are a universal adaptation to the grinding machine. One circle is enough to complete all stages of grinding. Such a circle is made of a metal base on which circles with different grit abrasive are fixed. Circles as they wear out can be easily changed to others, they are consumable items. The base of the nozzle can work for a long time.

    Appointment:
    • Surface cleaning before painting.
    • End and edge processing.
    • Parquet flooring.
    • Grinding wooden surfaces.
    Nozzles for polishing wood

    For polishing wood, circles, discs and brushes are used. Their working parts are made of fine sandpaper, felt, sponge and other materials.

    Consider the main types of nozzles for polishing. There are many varieties of polishing nozzles in the distribution network, so there are no special problems with their search.

    Recommendations for using nozzles
    • It is forbidden to use discs from a circular saw with an angle grinder when fitting parts before grinding, since the angle grinder is a high-speed tool. In this mode of operation, the saw teeth do not withstand prolonged use and are destroyed, flying apart at high speed. This violates safety precautions.
    • Some circular saws are large, so the craftsmen remove the protective cover, which is also very dangerous.
    • Frequent mode changes contribute to overheating of the grinder motor, therefore, interruptions in operation should be taken to cool it.
    • Due to the loose structure of the tree, the saw blade may jam. Therefore, it is likely that the angle grinder will break out of the hands, which can lead to personal injury.

    Wood processing angle grinder is carried out only in the form of rough processing, grinding, and other surface work. And for cutting and cutting sheet materials, it is better to use specially designed tools for this.

    How to understand the disks for an angle grinder for metal

    For high-quality metal cutting, it is not enough to choose an angle grinder, you still need to correctly select the disk.

    Using various nozzles for angle grinders, you can cut, polish and polish metal, as well as many other materials. Among the variety of metal disks for an angle grinder, making the right choice is sometimes difficult even for a professional.

    To understand the types of consumables and the features of working with them, this article will help.

    Classification of interchangeable angle grinders

    According to their functional purpose, nozzles for an angle grinder are divided into:

    • Cutting off. The most common type of disc used in angle grinders. They are used for cutting materials of various density and origin. Circles for working with different materials vary in design and cutting method.
    • Grinding and polishing. With their help, the surface of the part gives a mirror smoothness or remove irregularities.
    • Sharpening and peeling. Purpose. sharpening the tool and cleaning parts from paint, rust and other layers.
    Cutting wheels

    Depending on the type of material being sawed, there are several types of cut-off consumables:

    1. For metal cutting. Designed for cutting metal products. They vary in thickness and outer diameter.

    The smallest is a cutting disc for an angle grinder of 125 mm, and the largest is 230 mm. Thickness varies from 1 to 3.2 mm. The larger the diameter of the disk, the thicker it is. However, small nozzles can have any thickness. This relationship between diameter and thickness is due to the speed of rotation.

    2. For cutting stone.

    The design and method of use of such nozzles are completely identical to consumables for metal, the difference is in the abrasive materials used for their manufacture.

    3. Sawing wood. Work using sawing replaceable elements for wood is very dangerous and fraught with personal injury. This design is a thin metal disk with sharp teeth.

    When rotated, it easily cuts wood. However, when it is jammed, the angle grinder may wrest the worker from the hands, as a result of which he may be injured.

    To avoid such incidents, when cutting wood, it is recommended that you follow these instructions:

    • It is strictly forbidden to remove the protective cover from the angle grinder.
    • It is necessary to use a replaceable element with a small tooth.
    • You can not use a powerful feed, since when jammed, the tool will inevitably fly out of hand.
    • If necessary, saw wood of large sizes with a powerful angle grinder, special fastenings (equipment) should be used for it.

    4. The diamond blade. It is essentially universal, which can cut materials of any hardness from the softest to the hardest. Most often, consumables of this type are used when cutting reinforced concrete, porcelain stoneware, stone and tile.

    For various types of sawn material, diamond blades of various designs are used.

    According to the design of the cutting edge, nozzles are distinguished:

    • With a solid cutting edge.
    • With cutting sectors.

    By the amount of spraying:

    • Large diamond spraying.
    • Fine spraying.

    An example is diamond interchangeable elements for cutting concrete, which have a cutting edge divided into sectors and spraying from small diamonds. In contrast to which, disks for stone work are a continuous circle.

    In appearance, it is almost impossible to determine the purpose of the diamond consumable, so when buying, you should carefully study the packaging. It displays all the information about this tool.

    Grinding and polishing models

    A huge variety of consumables are produced for angle grinders, which allow grinding and polishing various surfaces.

    By the type of coating used, the disks are divided into:

    • With sandpaper.
    • Spongy.
    • Felt.
    • Cloth.

    In addition to its own grinding coating, together with many replaceable materials, fine abrasive pastes are required.

    Coarse grinding of the surface is carried out using finely abrasive grinding wheels. Final polishing is carried out with a cloth or felt nozzle.

    Sharpening and peeling nozzles

    For grinding various surfaces, replaceable elements of various configurations are produced.

    The most common are:

    1. Twisted cones. Cleaning wheels for metal for an angle grinder, indispensable if necessary to clean the surface of old paint or cement mortar. The twisted cone consists of steel cups, with steel wire brushes mounted on their edges.

    The diameter of the wire depends on the required stiffness of the brush. The harder the cone, the thicker the wire.

    2. Sharpening consumables. They are used for rough processing of metal products, such elements can be used to clean welds or sharpen tools. Widespread grinding wheels of small diameters. Since a small angle grinder is more convenient to carry out similar types of work.

    The sharpening nozzle is easy to distinguish from the cutting one due to the large width (at least 5 mm.) And the recess on the inside, due to which, you can sharpen the tool with the flat side of the circle.

    3. Diamond peeling elements. A distinctive feature of this type of disc is that the work is carried out only by the peripheral part of the nozzle, on which diamond spraying is applied. For other properties, such a replaceable element is similar to abrasive.

    Diamond consumables are used for grinding stone, concrete and similar materials. This design is ideal for removing small areas of concrete screed.

    Marking

    On the front side of the disk for an angle grinder, all the information necessary for the master is indicated.

    When choosing, you should immediately pay attention to his specialization. Also, the outer diameter, expiration date and maximum revolutions at which it can work without collapsing are indicated.

    Shelf life is a very important parameter, after its expiration. the element is better not to use.

    The dimensions of the cutting wheels for metal for the angle grinder are plotted on the outside of the nozzle and consist of three parameters separated by the “X” symbol. The dimensions of the discs are characterized by an external diameter, thickness and landing diameter, the standard size of which is 22.2 mm.

    The outer diameter determines which angle grinder it is suitable for. It corresponds to the sizes of angle grinders, consumables are available in 115, 125, 150, 180 and 230 mm.

    Installing a circle of a larger diameter than the angle grinder is designed for is strictly prohibited!

    The thickness of the circle determines the ease of cutting, the thinner it is, the easier and faster you can cut any design. However, a thin element is easier to break during the cutting process, although for low-power (battery powered) grinders, the use of circles of this thickness is most optimal.

    The specification of the cutting disc is encrypted in a four-digit code containing information about the main components that make up cutting grains and ligaments. When choosing a replacement element, it is important that its purpose matches the type of material being cut, otherwise the cutting quality will be poor and the disc may break.

    Features of consumables for cutting aluminum

    Aluminum is a very soft and viscous metal, therefore, when cutting it, the cutting disc wears out faster, and the risk of jamming increases many times. After cutting an aluminum alloy, the angle grinder circle becomes unsuitable for steel cutting. Due to the intensive clogging of its pores with metal particles.

    Aluminum does not give sparks when cutting it, but small shavings, invisible to the eye, can injure a worker, therefore, when working on this plan, the use of goggles is mandatory.

    For high-quality cutting of aluminum alloy, the following requirements must be observed:

    • Dripping kerosene on the working seam.
    • Observe fire safety regulations.
    • Acquire the appropriate circle.

    For aluminum, aluminum cutting wheel 125 mm in diameter is most often used, ideally suited for this type of work.

    P.S. For high-quality and safe work when processing metal, it is important to study the features of all types of interchangeable elements for an angle grinder. Taking into account all the parameters set forth in the article, you can choose a drive that is ideally suited to certain working conditions. And having the best price.

    • Diamond blade for angle grinder. This nozzle can be called universal. it is able to cut almost any material, from soft to durable. The most widespread such nozzles were in the field of cutting granite, reinforced concrete, artificial and natural stone and tile. For each of these materials, there are separate varieties of discs. some of them have a solid cutting edge, and some are torn with slots. Also, depending on the purpose of these circles, they may have a large or small fraction of diamond spraying. For example, disks for a concrete angle grinder have fine spraying and special transverse recesses along their entire diameter. In contrast, the diamond blade for stone angle grinder has a solid cutting edge.

    Visually, the purpose of diamond discs is difficult to determine, therefore, when purchasing such nozzles, carefully read the packaging. everything is written in detail about its purpose.

    Grinding and polishing discs for angle grinder

    There are a lot of varieties of grinding and polishing wheels. depending on the required surface quality, disks with removable emery paper, felt, sponge, and even cloth can be installed on an angle grinder.

    Most of them require special fine abrasive pastes or even liquids to work. For coarse grinding and grinding, finely abrasive grinding wheels are used. Grinding discs for an angle grinder allow you to bring almost any materials to the necessary roughness. such nozzles are used even in auto repair shops to polish automobile bodies.

    Disks for sharpening tools and peeling nozzles for angle grinder

    Among this type of fixtures, in order to expand the functionality of an angle grinder, three types stand out significantly. twisted cones, abrasive grinding wheels and diamond grinding machines.

    • Twisted cones are used for peeling metal and stone surfaces. if we are talking about removing old paint or thoroughly dried cement mortar, then the best replacement tool can hardly be found. It is made in the form of steel cups, wire brushes are installed around the perimeter of which. The size of the wire can be different. depending on the roughness of the processing, the cone can be equipped with both thick and thin wire.

    • Abrasive grinding wheels. Such nozzles are designed for rough processing of metal. with their help they clean welds and sharpen all kinds of cutting tools. As a rule, such nozzles are most widely used on small angle grinders. this is due to ease of use. Such a nozzle can be distinguished from cutting wheels in thickness and shape. their inner part has a recess, which allows the grinding process to be carried out with the flat part of the wheel, and the thickness cannot be less than 5 mm.

    • Diamond grinding wheels. In principle, they are somewhat similar to abrasive tool-grinding. Only in contrast to them, processing with a diamond tool of this type can be performed only by the periphery of the disk on which the cutting edges are placed. In contrast to its sharpening counterpart, peeling diamond is not designed to work with metals, its ridge is the peeling of concrete, stone and the like. If we are talking about removing a small area of ​​cement screed, then come up with something better than this diamond will not work.
