Cut metal with a disc on a stone

news

Like all other tools, the angle grinder is divided into classes, into professional and household tools, as well as by their design features.

This is perhaps the most widely used tool besides the drill. Many people work with an angle grinder, but not everyone is wondering about the correctness of the manipulations performed, from the point of view of personal safety and quality of work. In this article, we want to devote you to the basic subtleties of working with this tool and consider in detail the following questions:

Let’s go in order.

HOW TO CORRECTLY CUT AN Angle Grinder?

Before you get started, you need to prepare your angle grinder. We mean the choice of rig (disc). The following points should be considered here:

• Disc diameter. Remember, the smaller the diameter of the disc, the more revolutions (higher rotational speed) it can withstand, and vice versa.
• The choice of disc depends, first of all, on the material with which you plan to work and the design features of your instrument.
• Pay close attention to the legend and markings on the disc. Having carefully studied them, you will understand whether the selected equipment is suitable for the proposed work.

Also, always follow safety precautions and wear special equipment such as gloves, goggles, long sleeved robes and closed shoes.

First of all, clear the workplace of unnecessary items. Securely fix the workpiece to be processed, having previously marked it on it, if necessary. Getting Started.

Always hold the tool firmly and confidently with both hands. Take a steady body position. You need to stand so that sparks, during work, do not fly onto clothes, and even more so in the face.

Always remember about such a thing as kickback. This is the most dangerous thing that can happen when working with a grinder. It can happen if the disc is strongly jammed in the workpiece. In such a situation, the angle grinder will be thrown back sharply. Monitor the process to avoid this.

Also remember that the power cord of the angle grinder must be isolated from sparks during operation. If you need to move the instrument to a different work surface, be sure to turn it off first, then unplug the power cord. The same should be done in the event of a power outage. As soon as the power goes out, turn off the instrument and then unplug it from the mains. If this is not done, then when power is restored, the angle grinder will start to work in a chaotic mode again and can cause irreparable harm to your health, others or damage objects around.

The most frequently asked question that arises among novice craftsmen is the following: How to cut an angle grinder correctly: for yourself or away from yourself? Many do not betray this special significance, but in vain.

Manufacturers of angle grinders advise their consumers the following: The tool should be used in such a way that the stroke (direction) of the cut coincides with the direction of rotation of the disc.

Experienced craftsmen have a clear answer to this question: You need to make a cut from yourself. This is for your safety. In case the angle grinder is pulled out of your hands, the tool will be thrown in the opposite direction from you. If you cut towards yourself, when the above situation occurs, the tool will fly to your feet. We will not describe the consequences. You can imagine them yourself.

If you are cutting parts or workpieces that have thick metal, cut them in an extremely straight line.

When working on a part such as a corner or when cutting a profile or profile tube, which are usually quite long, cut the overhanging edge. Otherwise, if you make a cut in the place between the supports, an outcome such as a jamming of the disc due to the deflection of the workpiece is possible.

If you are cutting a corrugated sheet (sheet metal sheeting), metal siding (metal siding) or metal tiles, take care of the presence of special anti-corrosion substances that need to be lubricated in order to avoid sudden corrosion.

In case you are cutting paving slabs or paving stones, get a special diamond cut disc.

Reinforced concrete, concrete and other similar materials must be processed with special discs for stone.

If you need to cut a gas or oxygen cylinder, be very careful as it may explode due to the remaining trace of gas or condensation. It is better not to carry out such work at home.

If you need to cut glass or, for example, a mirror. the most trivial ceramic disc will suit you.

When working with material such as wave slate, do not apply extra effort to avoid chipping and unevenness.

Handling rubber with an angle grinder is possible, but unnecessary. If you understand what we mean.

Grooves, springs, rebar or channel can also be cut with an angle grinder.

Need to cut drywall or polycarbonate? Do this very carefully to avoid chipping and breaking the material. You will need neatness if you need to cut glass mosaics. For example, if you are cutting off excess parts from a pasted arch, cover the cut and the part to be cut off with masking tape or construction tape. This minimizes the possibility of cracks and prevents debris from scattering on the floor after cutting.

HOW TO CUT TILES WITHOUT CHIPS Angle Grinder?

As we said above, the range of applications for the angle grinder is incredibly wide. She also acts as an excellent helper when cutting material such as tiles or tiles. But, a logical question arises regarding the equipment: How is it better to work on tiles? To carry out this type of work, you need to get a grinding diamond wheel and a tile holder. It is hardly possible to work without dust with this material, so take care of a protective mask in advance.

Let’s take a closer look at the process itself and methods of cutting tiles or tiles without chips.

• The easiest way is to cut straight. Fix the tile well so that its edge remains suspended along the mowing line of the cut and get to work.
• The next method to be noted is cutting at a 45 angle. This method is more complicated than the first one. First, we cut the ceramic tile with a straight cut. Then, when cutting the disc, the angle grinder is guided at an angle and remove the unnecessary part. Next, we grind the cut with sandpaper.

HOW TO CORRECTLY CUT ANGLE GRINDER METAL?

To begin with, let’s talk about the dangers that await the master when cutting metal with an angle grinder, namely:

• Fragments of the disc, in the event of a break;
• Powerful stream of sparks and small abrasive particles;
• In some cases, the inability to hold the instrument in the hands.

Now, a few tips for working with metal.

If you have no experience in this type of work, then, for a start, it is worth practicing on unnecessary details. If in the process of work, you decide to change the cutting plane when the disc is inside the workpiece, this will immediately lead to its breakage.

To increase the life of discs, especially expensive ones, they need to be cooled. This is done with water. It is necessary to water the cutting area. It is advisable that you work with a partner who will carry out all these additional manipulations.

Also, breaks of 5-7 minutes every 20-30 minutes of work will help to increase the service life of the equipment, and the tool itself. This rule is especially important when working with household angle grinders. This way you will protect your instrument from overheating.

You should also remember that you should not put pressure on the angle grinder during operation, otherwise it may fail due to overheating, or the disc will jam. If you feel that performance is too slow, try changing the drive.

CAN the angle grinder CUT WOOD?

Many seasoned craftsmen claim that cutting wood with an angle grinder is to be. Our opinion: indeed, it is possible to cut wood with an angle grinder, but it is extremely unsafe, inconvenient, slow and of poor quality. And that’s why.

Firstly, during operation, the disc of an angle grinder gets very hot and becomes incredibly fragile. The slightest misalignment can result in a ruptured disc. You can find out about the consequences of this situation from the pictures on the Internet.

Secondly, when working with a disc equipped with victorious solders, these solders can easily end up under the skin. And this is a direct way to the hospital, because you cannot remove them on your own, plus everything is fraught with infection.

Thirdly, when using a disc on wood, the teeth can grab more wood than you expect, and this, in turn, will lead to that. that the angle grinder will simply rip out of your hands. It is very dangerous!

We hope we have explained in an accessible way why you cannot use an angle grinder when working on wood and you will not even try.

But, as practice shows, many craftsmen at home resort to using an angle grinder in the process of processing materials such as chipboard, chipboard, laminate, OSB board or plywood. This should be cut as carefully as possible and in compliance with all safety measures. Otherwise, you can not only spoil the material, but also be injured.

HOW TO EXACTLY CUT AN Angle Grinder?

In order not to spoil the workpiece and make a high-quality smooth cut of the angle grinder, you will need to perform a number of preparatory measures, which we will discuss in this part of the article.

• Markup. All ingenious is simple. first we mark, then we cut. Take pipe cutting as an example. First, use a chalk or marker to apply the size, then use paper or duct tape. The main thing is that the edge is even. We take the selected auxiliary material and carefully wrap it around the pipe. Its border will be a clear and accurate marking of the cut. When performing work, it is important to remember that under no circumstances should you change the position of the tool stroke. Otherwise, the disc may jam or break. Also, do not put additional pressure on the tool, as this will immediately be reflected in the curvature of the cut and spoil your workpiece.
• It is very important to choose the right thickness of the circle. There is a simple axiom at work: the thicker the material you are working with, the thicker the disc should be. When choosing tooling, consult with an expert in the field and pay attention to the marking of the grinding wheel applied to his shirt.

HOW TO SAFELY CUT AN Angle Grinder?

The work of an angle grinder is a matter that requires constant attention and control, because the consequences of accidents are irreversible. Therefore, before starting work, take care of the following:

• Take care of the protection of all parts of the body: face, hands, eyes.
• Clean the work area from excess, especially the place where the sparks fly out, remove all combustible materials away.
• The workpiece to be machined must always be securely clamped.
• Be sure to install the protective cover.
• Hold the tool firmly while working.
• At the end of the work, wait until the rotation of the disc has stopped completely, place the angle grinder with the disc upwards so as not to damage it, unplug the tool from the mains and make sure that there is no smoke or signs of fire.

WHAT CANNOT BE CUT with an angle grinder? BASIC ERRORS

The list below shows the materials you can work with your angle grinder. It is forbidden to work with materials that are not on the list.

• The angle grinder is perfect for cutting materials such as cast iron, metal, steel, copper, aluminum, iron, titanium. You can cut stainless steel or galvanized.
• With the appropriate attachments, you can also work with plastics, ceramics, glass, plexiglass and porcelain.
• Stone, granite, marble, asphalt, concrete or walls made of it, brick, porcelain stoneware can also be processed by an angle grinder.

an angle grinder is useful if you need to cut water pipes or old heating.

One of the main factors that guarantee the quality of work is the right tooling. If you have any questions or want to purchase discs, please contact our managers at the specified phone numbers. They will recommend suitable discs and advise you on all questions of interest.

Mechanical methods

The classification of mechanical cutting methods is usually based on the answer to the question: how to cut metal?
Cutting with a hacksaw and scissors for metal

Cutting with scissors: a) cutting the sheet into strips; b) cutting with leaf cutters.
Cutting a round shape: c) wrong; d) correct

At home, metal is usually cut with an ordinary hacksaw. This process is quite laborious. It is greatly simplified if you have a mechanical hacksaw at your disposal.

Unlike hacksaws, there are many types of metal scissors:

• Hand shears allow you to cut relatively thin sheet metal. They allow you to do this quickly and accurately by following the cut line correctly. There are several types of hand scissors: finger, power, chair, lever, for curved cutting.
• Slotted scissors carry out both straight and curved cutting. They allow you to cut metal in confined spaces while maintaining a high quality cut. Powered by an electric motor.
• Guillotine shears can cut metal with high precision. The main advantages are the absence of defects, high cutting accuracy, the safety of the outer coating of the material being cut.

Types of guillotine shears:

Hand scissors can cut a relatively thin sheet of metal.

• Hand scissors. The main disadvantage is that the developed force is not enough for cutting if the metal is very strong.
• Mechanical scissors. Powered by an electric motor, so the productivity is significantly higher than that of manual guillotines.
• Hydraulically driven shears. Provide very high accuracy of work. In addition, they can be equipped with a CNC, which makes it possible to significantly increase their productivity by storing typical parameters of cuts in the memory.

Reciprocating and circular saws, angle grinders

Reciprocating saws are similar in principle to a jigsaw. Outwardly, they look like an electric drill, only instead of a drill. a saw pushed forward with a length of 10 to 35 cm, making a reciprocating motion. Usually the saw is powered from the mains, but battery versions are also available.

Reciprocating saws are used for accurate and fast metal cutting.

For different types of work, different types of saw blades are used. They change easily, like drills in an electric drill. The fastening system is reliable and efficient. Knowing what to work with, you can choose the right file. For example, the greater the curvature of the cut, the narrower the canvas should be.

Working with a reciprocating saw requires skill, a steady hand and a good eye.

It is easier to work with circular saws. Their cutting discs are usually made of hard high-alloy alloy or special high-speed steel. Saws are designed for cutting a variety of metal profiles made of a wide variety of metals and alloys, provide a narrow kerf, a small amount of chips.

To choose the right saw, you should pay special attention to the saw blade, in particular to its diameter. The larger it is, the more possibilities the instrument has. After the cut, additional processing is usually required to remove sharp edges. The disadvantages include rather large dimensions and a rather high cost.

Circular saw can cut copper, aluminum and other non-ferrous metals.

Most consumers don’t even know that the “angle grinder” is an angle grinder. The fact is that this miracle of technology comes from an angle grinder, and our people do not like long names. In most cases, an angle grinder equipped with a steel cutting disc perfectly replaces a circular saw for metal, although, as the name suggests, it was originally intended for grinding.

Today, many people use it as a saw, and not for grinding, although a modern angle grinder can be cut, cleaned, polished, etc. over, almost all materials can be cut and grinded. The main thing is that you don’t need to buy various tools. For various materials and works, only different consumables are purchased, and the machine itself only needs one.

Tools and methods for cutting metal

Cutting is one of the most common operations in the processing of metal workpieces.

But here the question immediately arises: how and with what metal is cut?

Metal can be cut mechanically or thermally.

It is customary to distinguish between two main groups of cutting methods:

• Mechanical. sawing, scissoring, etc.
• Thermal, based on the use of a jet of any substance. gas, water, etc.

Thermal methods

Cutting methods belonging to this group can be divided into the following types: gas and gas-electric cutting of metals.

In these cutting methods, the metal is heated by a gas (oxygen) flame, and power sources are not used. There are three main ways of such cutting:

Oxygen cutting of metal involves heating it. hot oxygen jet cuts metal and removes oxides that arise there.

• Oxygen. With this method, the metal in the cut zone burns out in an oxygen jet, and the formed oxides are blown out by it.
• Oxygen-flux. A flux powder enters the cut area, which facilitates the cutting process due to chemical, thermal and abrasive effects.
• Oxygen lance. The high temperature is created by the combustion of the so-called spear. a tube through which a stream of oxygen is blown.

The main advantages of these methods:

• low cost;
• thick layers of metal can be cut.

• high metal consumption;
• low accuracy;
• the need for additional processing of parts;
• low cutting speed;
• large cutting thickness;
• thermal deformation of metal.

In gas-electric cutting, the metal is heated by a power source, and the melt is removed from the cutting zone by a gas jet. There are two ways to do this:

• Air arc. liquid metal is removed from the melting zone with a jet of compressed air.
• Oxygen-arc. the metal heated in the arc flame burns out in the incoming oxygen stream, it is blown out by it.

It is mainly used to correct defects in welded seams. The main disadvantage is the carburization of the cut site due to the combustion of carbon electrodes.

Plasma cutting is by far the most advanced, fastest and most cost effective way to cut metal.

A very promising and rapidly progressing method. The cut metal is melted by a jet of plasma. ionized gas with a temperature of tens of thousands of degrees. A plasma jet is created in a special device. a plasmatron. from an ordinary electric arc due to its compression and injection of a plasma-forming gas into the reaction zone. Two main processing schemes:

• Plasma jet cutting. With this method, an arc occurs between the electrode and the tip of the plasmatron. The work piece is not included in the electrical circuit.
• Plasma arc. an arc occurs between a non-consumable electrode made of a refractory material and the metal being cut. An effective and more commonly used method.

The advantages of plasma cutting compared to gas cutting methods:

• high cutting speed;
• versatility of application;
• the ability to cut with high precision and quality;
• no need for expensive gases;
• the ability to cut parts of complex shapes;
• safety and environmental friendliness.

• high cost and complexity of equipment and its maintenance;
• impossibility of cutting workpieces with a thickness of more than 80-100 mm;
• limited angle of deviation of the cut from perpendicularity;
• increased noise level.

The remaining thermal methods, due to a number of reasons, of which the main one is the high complexity and cost of equipment, have not yet become widespread. We will limit ourselves only to their listing:

• hydro and water jet cutting;
• laser and gas laser cutting;
• electrical erosion method;
• cryogenic cutting.

Summarizing all of the above, we can conclude: there are a lot of methods and types of equipment for cutting metals. It is possible to choose the most suitable methods correctly only by weighing many factors, primarily financial opportunities.

Basic rules for safe work when cutting metal angle grinder

The layout of the most dangerous sectors during the operation of the angle grinder, taking into account the rebound and destruction of the disc.

The most necessary condition for cutting is strict adherence to the rules of safe work.

Angle grinder manufacturers are constantly trying to minimize the risk of injury and injury by inventing and improving various protection systems. But no one cares about the worker like himself.

The main dangers that arise when cutting metal are the flight of fragments of a broken disc, the flow of sparks and the smallest abrasive particles, the inability to hold the tool in your hands.

If the disc breaks or gets jammed, the angle grinder can be pulled out of your hands at the most inopportune moment and with great force, therefore, before starting work, you should consider the direction of its possible movement.

Safety rules cannot be neglected even when performing small work.

Before starting work, you should:

• Protect face, eyes, hands, and if possible all parts of the body.
• Remove all combustible materials and objects that are in the direction of the emission of sparks.
• Clamp the workpiece to be machined in a vice, if possible. Do not hold the workpiece with your free hand or press with your feet.
• If you install a new disc, you need to “spin” its angle grinder at maximum speed, placing it further: the disc may be defective and fly to pieces.
• Install, adjust and secure the protective cover.

It is best to protect your face with a special face shield when working with an angle grinder.

During work, you should:

• When replacing discs during rest, disconnect the angle grinder from the mains.
• Use goggles or face shield to protect eyes and face. professionals use both for extended work.
• Hold the angle grinder firmly during all work.
• To replace a disk, you need to wait until it completely stops.
• Wear protective gloves. It is undesirable to use cotton gloves, they do not provide sufficient protection, they can ignite, and the threads wrap around the spindle of an angle grinder or disc.
• During work, you need to position yourself so that the face, and, if possible, all parts of the body are not in the plane of rotation of the disk.

At the end of the work, you should:

• wait until the disc rotation has stopped completely and only then put the tool on the floor with the disc facing up so as not to damage it;
• disconnect the angle grinder from the network;
• make sure there is no smoke or other signs of fire.

A typical mistake that is made when cutting metal: if the diameter of the new circle is larger than the size of the protective cover, it is removed. The casing is a protection in case the disc breaks and shatters during the metal cutting process.

Instead of a disc, many people put cutters, saws or other materials at hand. Doing this is strictly prohibited.

How to cut metal angle grinder correctly. Practical tips and tricks

If long pipes are resting on supports, the overhanging edge must be cut. If you cut them in the middle, then due to its own weight, the metal will bend and clamp the disc.

If you do not have the skills to handle an angle grinder, then before starting work, you should learn how to cut on unnecessary parts.

The cut-off wheel only accepts radial forces. Attempting to change the cutting plane while the blade is inside a metal piece will break it.

The disc heel (the near-bottom part of the circle) cuts metal more efficiently.

In order for the angle grinder and discs to serve for a long time, you need to take a break for 20-30 minutes every 5-7 minutes of work. This rule is especially important for low-power angle grinders who are afraid of overheating.

To increase the service life of the discs, especially expensive ones, and to cool the metal, the place of the cut must be watered. It is advisable to carry out the work together.

Aluminum is a very tough metal. When cutting a part of a large thickness, kerosene must be dripped into the seam, observing fire safety rules.

For molding, cutting of sheet metal, curly carving, you should use worn-out discs. “stubs”, so do not throw them away immediately.

Correctly cut the corner not in one go, but separately both shelves.

If long enough pipes, corners, fittings lie on the supports, cut the overhanging edge correctly. If you cut between the supports, the part will bend due to its own weight and jam the disc.

Thick parts are cut only in a straight line. If you need to cut a curly part, straight-line cuts are made first, then the remaining unnecessary parts are removed.

Do not put pressure on the angle grinder. This will cause the blade to jam or break and overheat the angle grinder. If the cutting process is slow, the blade should be replaced.

The resulting cut should not be processed with the side of the disc. For this, a different type of disc is used.

Melted particles of metal and abrasive, falling on plastic products, glass and car headlights, get stuck in them, and then it is almost impossible to remove them. Therefore, before starting work, they need to be removed or protected.

How to choose the right discs

There are symbols on the circle that will help you choose the right circle.

When choosing discs, you need to know what they will be used for, pay attention to their diameter and thickness. These are the main parameters of the disks.

The smallest diameter is 125 mm, and the maximum, of the generally available ones, is 250 millimeters. In professional angle grinders, discs can be larger in diameter.

The thickness of the cut part and the maximum depth of cut depend on the diameter of the disc.

If you plan to cut only metal, you need to purchase a cutting disc. It has the smallest thickness from 1 to 1.2 mm, for industrial angle grinders. up to 2.5 mm. This will ease the physical exertion of the angle grinder and the worker. The cut is neat.

If you plan a curly thread on thin metal, then it is done with a disc of the smallest diameter or an old, almost worn out disc.

Experts say that the angle grinder does not have any particular difficulties when cutting metal, even for beginners.

How to choose the right angle grinder

the angle grinder should fit comfortably in your hand.

The correct choice and quality of the angle grinder itself determines the quality of work and the safety of the worker.

When choosing a machine, you should be guided by its main parameters: power and diameter of the cutting abrasive wheel. Its weight is also of no small importance, since it is often necessary to work “by weight”, and dimensions so that you can perform work in inconvenient and hard-to-reach places.

Most buyers at the sight of a powerful angle grinder are somewhat intimidated by the fact that it is more difficult to cope with it than with a low-power one. This is a misconception. Low-power angle grinders are more likely to jam discs, i.e. they are physically unable to “pull out” the disk under heavy loads. The situation of how the disk and the machine itself will behave after reducing the load is unpredictable. The angle grinder will most likely tear out of your hands. The consequence of this will be a break in the disc, damage to the machine and injury to the cutter. Therefore, it is better for novice craftsmen to purchase an angle grinder for a 125 mm disc with a power of 800-1000 W and a spindle speed of 10,000 rpm. This power is enough to cut iron.

For cutting metal, there are machines for a 115 mm disc powered by batteries, but, as practice shows, with their high cost in solving household problems, they do not justify themselves.

The handles of the angle grinder must be rubber or made of a material that will damp vibrations from the machine.

But none of the technical characteristics reflects the convenience and safety in work. The angle grinder should lie comfortably and securely in your hand so that when working with metal you focus on it, and not on how to hold the tool in your hands. It is desirable that the grips are rubber or vibration-damping material with indentations for the fingers.

Low-power angle grinders usually do not have an additional handle.

If any inconvenience was found during the selection, you should look for an angle grinder of a different model.

How to cut metal with an angle grinder

There is an opinion that the very concept of “angle grinder” has come into our use because for the first time this tool was brought from an angle grinder. This is partly true. But they developed and began to produce it in Germany. He first came to us from an angle grinder, where he began to be produced in the seventies. Angle Grinder. Correct Tool Name.

When working with an angle grinder, it is imperative to observe safety precautions, namely: wear glasses, gloves, a helmet and a protective apron.

It is impossible to imagine the work of builders, repairmen, mechanics, locksmiths today without an angle grinder. With its help, you can cut a variety of materials, including metal: fittings, bar, water pipes, corner, profile.

The resulting sections can be grinded, polished, sharpened. A large selection of interchangeable attachments makes this tool irreplaceable and versatile.

At the same time, it is the most traumatic tool.

To cut metal, an angle grinder will need:

• mask;
• glasses;
• disks;
• Angle Grinder;
• metal.

Is it possible to use an angle grinder for cutting metal tiles and corrugated board?

At a time when they just started using metal tiles and corrugated board, the instructions said that using an angle grinder for cutting these roofing materials is strictly prohibited. This is explained by the fact that on both sides they are protected with zinc and polymer coatings and painted.

The abrasive disc heats and melts the material. The slices are ragged. Flying sparks also break the paint. All this causes corrosion of the material and a reduction in service life.

Recently, however, builders have begun to use an angle grinder for this work. This greatly facilitates the work, it can be carried out directly on the roof. After cutting, the edges must be treated with anti-corrosion agents, primed and painted.

Correctly cutting metal with an angle grinder is easy. Everything can be learned. The main thing is to follow the safety rules and follow the recommendations.

How to cut an angle grinder correctly?

After a suitable nozzle has been selected, the workplace has been cleaned and all the necessary safety operations have been performed, you can start the work itself. Knowing exactly how to cut an angle grinder is important here.

To avoid injury and damage to the instrument itself, it is enough to follow simple rules:

• Please note that the line of the cut itself should not rest against the master, but pass by him. If the disc sticks, the jet motion of the angle grinder will pass it;
• Pay attention to the position of the protective cover. it will provide reliable protection if it is between the circle and the master;
• Do not apply force to the tool. the angle grinder will do the job on its own, you just have to hold it and direct it in the right direction. Excessive force will only lead to a skewed circle;
• Never turn on your clipper if the blade is still in the cut;
• You need to start cutting profiles at the place where the cross-section is the smallest;
• When working with stone, concrete or tiles, dust naturally occurs, from which it is extremely important to protect the respiratory system. You can use special covers with nozzles for a vacuum cleaner or simply suppress the dust with water;
• Be especially careful when cutting the walls. fittings, pipes, cables and other elements can get under the circle, which will lead to a reverse impact.

Remember that before cutting and sawing an angle grinder, you should familiarize yourself with the characteristics of the tool itself and the working material.

What can you grind an angle grinder

Despite the fact that the angle grinder is primarily intended specifically for grinding, it must be prepared separately for each operation. A support wheel mounted on the tool shaft significantly contributes to correct and safe work.

To process wood, an emery wheel must be glued onto the platter. Sandpaper is selected for the material purely individually. This is done by the number of the paper itself. The modern assortment makes it easy to find a circle of the required diameter and size. An additional convenience is the presence of Velcro on the emery wheel, which allows you to quickly change them to an angle grinder.

Thanks to the angle grinder, light sanding of concrete has become possible. For this purpose, it is recommended to purchase a protective cover. He will protect the master from flying dust. Also, such a casing has a branch pipe for connecting a vacuum cleaner.

For grinding metals, a standard metal grinding wheel is perfect. Such a nozzle has different diameters, thicknesses and different grains of the grinding surface. Note that if you are planning to sand a really rusted surface, then first you should go over it with a metal brush.

Can plexiglass be cut with an angle grinder?

Thanks to the angle grinder, you can easily cut the plexiglass. For this operation, an ordinary ceramic circle will be sufficient.

How to Use The Angle Grinder | Stone Carving Tutorial

It is necessary to make a contour cut, and then deepen it. The cut glass will need to be moved to the edge of the table and broken. Remember to cut this material carefully so as not to damage it.

Cut off, clean up, grind. how to work properly with an angle grinder

An angle grinder (angle grinder), also known as an “angle grinder”, is an effective but extremely traumatic tool. The use of this machine inappropriately enough often leads to various types of injury, damage and injury, in some cases fatal. In most cases, such injuries are inflicted on themselves by non-professionals who for the first time hold such a tool in their hands and have an idea of ​​its work only in words. That is why it is of great importance to study safety measures, operating rules and the use of protection in the process of working with an angle grinder.

In order not to get lost among the multitude of “empty” tips and unnecessary recommendations, choose only the right sources of information. How to use an angle grinder correctly, what protection to use and much more you will learn just by reading this article.

What you can do an angle grinder and where to start

Such a tool allows you to confidently cut, grind, clean and polish many well-known materials, such as concrete and tiles, metal and wood, brick and others. At the same time, for each specific type of work, a special replaceable nozzle will be required. In some cases, such a tool can be used for other purposes, such as cutting an angle glass grinder or sharpening cutting surfaces (knives, drills, etc.).

This power tool is indispensable in the process of construction or repair work. It is actively used in car repair shops, utilities, during rescue operations and in other areas of our life. In other words, the angle grinder is widely used in industry and in everyday life.

The very work of an angle grinder is a hazardous operation. Before starting it, it is important to prepare the instrument itself. In this case, the choice of the nozzle plays a special role. It is important to consider the following points here:

• The diameter of the saw blade. the smaller its value, the greater the rotational speed, which means that it is able to withstand a greater number of revolutions;
• The working material directly affects the choice of consumables. For example, for metal pipes, an abrasive disc, and concrete. diamond;
• Study the symbols and markings of such consumable carefully. This will allow you to understand if the given attachment is suitable for the intended operation.

Types of attachments for an angle grinder

Angle grinder discs are widely used in different operations and must be changed for different materials. over, each of them has unique properties and design. That is why it is so important to choose the right consumable for your angle grinder.

Depending on the purpose, they are:

• detachable. for cutting or sawing materials;
• saws. for cutting various wood products;
• roughing. for grinding metal, concrete and wood blanks;
• stripping. for removing rust from metal surfaces and removing other types of stubborn dirt.

Flap discs are among the most common types of scraper discs. Such tools are suitable for processing materials from metal, plastic and wood.

Attaching the accessory to the angle grinder

• Disconnect the tool from the mains and jam the rotation shaft with the attachment by means of a special button;
• The lock nut must be unscrewed. To do this, use a key with two projections;
• Remove the old drive. After that, a new one can be installed on the mounting flange;
• Screw in and secure the lock nut with a wrench.

Safety when working with an angle grinder

A really huge role is played by safety precautions when working with an angle grinder. The most important nuances of safe work are reduced to a few simple rules:

• Think carefully about the protection of the whole body. eyes, face, hands;
• Remove all unnecessary items from the workspace. This is especially true of the place from which sparks can fly out;
• Hide all combustible materials away;
• Make sure that the fixation of your workpiece is really reliable;
• Check the fixation of the workpiece again (!);
• Hold the tool firmly with both hands during work;
• It is not necessary to directly influence your angle grinder, namely to put pressure on it while working. Let the disk do everything on its own;
• After completing the work, wait until the rotation stops completely, then put the angle grinder with the disc upwards so as not to damage it;
• Unplug the device from the mains and make sure there is no smoke or fire.

How to cut slate. an overview of tools and cutting methods

Flat and corrugated slate sheets are widely used as roofing materials. During their installation, there is a need for cutting, which is a rather specific operation.

How to organize slate cutting

Slate is characterized by sufficient brittleness, which is why very small asbestos fibers and particles are formed during the breaking or sawing of sheets. As you know, asbestos is one of the harmful substances that provoke the occurrence of cancer. So that cutting the material is not accompanied by its destruction, with the appearance of asbestos dust, you need to know what the slate is cut with and use protective equipment.

Requirement for cutting slate sheets:

• Mandatory use of personal protective equipment. For the respiratory system, this is a respirator, for the eyes. special glasses, for the skin. gloves and thick clothing. In addition, a lot of noise is generated during the operation of the cut-off electric tool: ear muffs will help from it.
• In order to reduce the amount of dust generated by an order of magnitude and make the slate not so fragile, the cut section is moistened with water before cutting. To do this, you can use wet rags or direct watering of the cut mowing line during operation.
• When working outdoors, it is important to find such a place that the resulting asbestos dust is blown away by the wind to the side of the operator.
• If the procedure is carried out indoors, there should be no one in it except workers. All doors must be tightly closed, taking measures to further seal them.

How to cut slate with an angle grinder. which disc is cut

This procedure can be performed using two types of slate discs:

Disc for stone. In this case, no significant effort is required. It is important to organize a constant supply of water in a thin stream to the point of contact between the angle grinder and slate. In this way, the disc is cooled and dust is prevented. The easiest way to do this is to have a helper with a garden hose or cut up plastic bottle next to it. When working alone, the water hose is secured in a convenient position for watering. Using an angle grinder and stone disc, it is best to cut along the slate wave. For convenience, before starting work, the sheet is marked out and laid on a flat surface. If the cut is made near the edge of the sheet, a wide board is installed under it.

If it is necessary to cut in the direction transverse to the waves, the procedure is divided into two stages. First, an incision is made on the convex ridges. Then, turning the slate over, the procedure is repeated: it turns out that the ridges that were below are on top. If done correctly, the sheet neatly splits in two. At the end of the work, the tool should be thoroughly wiped from dust, especially its working part. The fact is that if the asbestos-cement layers become fossilized, it will be very difficult to remove them from the surface of the disc for an angle grinder on slate. Use a soft dry cloth for cleaning.

Diamond wheel. Using an angle grinder with a diamond wheel, you can cut slate in any direction. For greater efficiency, it is pre-wetted, increasing the elasticity and pliability of the material. In addition, it will significantly reduce the amount of dust generated. If the cutting is carried out in winter, then the slate sheets can simply be laid on top of the snow: in this case, most of the asbestos dust will simply be absorbed into the snow cover.

In addition to cutting in any direction, the diamond angle grinder can also grind the edges of the slate sheet. This improves the resistance of the material to climatic influences. It is also convenient to cut the corners of the sheets with a diamond wheel if they do not move by half during laying.

How can you cut slate from power tools

In addition to the angle grinder, a cutting machine equipped with a stone cutting disc can be used to cut slate. The preparatory procedure here is the same as in the case of an angle grinder: the sheet is first marked and then moistened. When working with a cut-off machine, it is important not to allow any shifts by running the disc exactly along the markings. It is usually not possible to cut the slate in one approach, therefore, after wetting the incision with water, the procedure is repeated again, due to which the incision deepens. As a rule, in order to comfortably break the slate, 3-4 such approaches are required.

For sawing wet slate, you can use a regular jigsaw, equipping it with fine-toothed blades. In this case, the spindle is set to the low gear mode. When using this tool, it is important to be very careful to avoid any pressure on the slate, otherwise it will crumble. The use of a jigsaw is justified only in the case of small volumes of such work.

Mechanical tools

If slate cutting is carried out indoors, or a suitable power tool for work is not available, classic techniques come to the rescue than cutting slate.

In this case, the wetted sheet can be cut in the following ways:

• Hand hacksaw. For this, a tool with replaceable blades and fine teeth is suitable. You should stock up on several such canvases in advance, since in the course of work they quickly become dull and clogged with asbestos dust. When cutting, it is recommended to avoid pressure, otherwise the fragile material may break.
• Manual cutter. In this case, it will be necessary to deepen the incision several times along the applied markings. Between approaches it is necessary to wet the line of the notch. When the cutter is 2/3 deeper than the plate thickness, it can be broken. To do this, a wooden plank is placed under the slate, just along the mowing line of the notch: after pressing the edges of the sheet, it will easily split into two parts.
• Hammer and roofing nail. For this, the line is carefully pierced with a nail in many places. It is advisable to make as many of these holes as possible. this will only contribute to the quality of the fault. When making holes in the direction longitudinal to the wave, the slate is turned so that this wave passes below. After applying a series of holes, a wooden block or rail is placed under them: by pressing on the edges of the sheet, they break it. To facilitate this procedure, it is allowed to tap the break line with a hammer.

To implement this method, you will need special slate nails. They are distinguished from ordinary ones by the presence of a special shape of the rod and a soft head, which allows avoiding splitting of sheets during driving. To speed up the process of equipping the slate with a series of holes, roofing nails are stuffed into the block. This kind of comb is usually used for constant work with slate sheets.

Cutting flat slate at home

To separate flat slate sheets, any method of cutting corrugated slate can be adopted. However, it is most convenient to cut smooth slate with an angle grinder with a disc over a stone. For the procedure, a flat surface is selected on which the material is laid. it can be a simple wooden flooring, or a dense soil area. The main thing is that the bottom base is not expensive, as it will be damaged during cutting. When cutting near the edge of the slate, it is advisable to put a wooden strip of the required length under it. Before cutting flat slate at home, you need to organize the supply of water to the work site to reduce the amount of asbestos dust

Regardless of which disc the slate is cut with, it is important to avoid haste and be as careful as possible. Any careless movement can lead to splitting of the sheets, which, as you know, cannot be glued. If such work is carried out for the first time, it is imperative to read the recommendations on how to saw off the slate. If possible, it is better to practice on an unnecessary old piece of material first.
