Is it possible to cut metal with a diamond disc is an angle grinder

4.5 inch Diamond Angle Grinder Blades for Metal and Steel Last Longer and Safer

Is it possible to saw wood with a diamond blade?

Diamond discs are used most often for working with granite, tiles and ceramics. For wood, it is better to use discs with teeth. When cutting wood with a diamond blade, the material will smoke and the tool will heat up quickly, which will take time to cool down. Therefore, it is best to use discs as intended for specific materials.

Go to our Catalog, where you can familiarize yourself with the entire range of our angle grinders and choose the optimal one for your tasks.

How to cut wood angle grinder

The angle grinder, originally designed for metal working processes, has so many different uses with different types of materials, and even wood is no exception. An angle grinder can be used for woodworking, but you need to be extremely careful and be aware of the high risk of hazardous work. When sawing wood with an angle grinder, the surface will not be smooth as, for example, when using a circular saw, but these errors can be easily corrected, the surface can be sanded.

You need to be extremely careful when cutting wood with an angle grinder and a suitable disc designed specifically for sawing wood, but they are not very common on the market. The special disc for working with wood material has teeth that increase the size of the cut. When working on wood, the thickness of the wood should not exceed 4 centimeters.

It is forbidden to work with circles for a circular saw, as the speed of revolutions per minute differs significantly. It is not recommended to use discs with coarse teeth, since there is a high probability of the teeth catching on the material, which will lead to the wheel jamming. The likelihood of snatching the tool out of hand in this situation instantly increases. If possible, set a lower number of revolutions.

The question is often asked: “Can an angle grinder cut wood with a disc for metal?” Of course you can, but not recommended. The wood will simply begin to smoke, an unpleasant odor will appear. It is better to use specially designated discs for this.

Sawing wood angle grinder

Compliance with safety rules is the most important rule and an appropriate marked disc for working with wood will ensure your work is perfect. When we cut firewood with an angle grinder, for a safe cut, it is required to fix the angle grinder according to the principle of a circular saw so that the angle grinder does not bounce under our feet. Such work is very unsafe, therefore, if there is an alternative replaced, namely a jigsaw, the same hand tool, or a circular saw, it is better to use them.


Pruning trees with an angle grinder also requires special care and it is worth remembering that small branches with a suitable disc can be sawed off for an aesthetic appearance, but thicker volumes of work should absolutely not be done on wood, especially on weight.

Sawing plywood angle grinder

To cut plywood with an angle grinder, wood discs are often used. Due to the large accumulation of dust, work in a well-ventilated area so as not to breathe burning odors. Sawing is best done along the pre-marked mowing line, pay attention before the end of the process so that the circle does not get jammed by the sawn-off part of the sheet.

Cutting an OSB angle grinder is safer and better with the right blade. The ideal disc would be the so-called three-tooth saw blade for wood, which is designed to work at high speeds. It will be a plus if the angle grinder has a speed controller.

Size classification

The cutting depth, the types of work that can be performed by it, the service life (for cutting wheels), compatibility with a particular tool depend on the size of the disc. You need to select the right one, taking into account the brand of the angle grinder, its power and the bore diameter.

Possible outer diameters of discs for metal for an angle grinder: 115, 125, 150, 180, 230 mm. Large outer diameters are not suitable for household tools. They are most often used in manufacturing. The outer diameter of the attachment must be suitable for the corresponding guard size of the angle grinder. The inner (landing) diameter must match the size of the tool shaft. The most common shaft diameter of household angle grinders is 22.2 mm.

The circles also differ in thickness. The thickness of the cut depends on this parameter. A thin disc makes thinner cuts, but will also last less than a thick one. Possible circle thickness: 1; 1.2; 1.6; 1.8; 2; 2.5; 3.2 mm. You can use a disc that is no more than 35% worn out.


Carbide. instead of diamond spraying, they have high-carbon molybdenum steels with additions of chromium and nickel at the edges. There are special-purpose carbide discs on sale: for thin, high-carbon, stainless steel, aluminum.

Material classification

Metal discs for an angle grinder are made of several types of materials:

  • Diamond.
  • Carbide.
  • Abrasive.
  • From metal wire

Classification by type of work

Types of metal processing angle grinder:

  • removing the old paint layer, including from metal surfaces;
  • removal of rust, scale, dirt;
  • cutting;
  • processing of welded seams;
  • grinding and polishing.

Wheels for metal to an angle grinder are:

  • Cut-off. They are designed for making cuts. The cutting discs for the metal angle grinder have a solid or segmented cutting edge. They are made from several types of materials. The difference in service life, price, features of work. The thickness of the cut-off wheel also plays a significant role. The thickness of the cuts and the durability of the nozzle depend on it.
  • Roughing (grinding). for grinding and removing from the metal surface of the old layer of paint, varnish, etc. A variety of roughing discs. flap: end, batch, with a mandrel. They are used in metal processing, cleaning welded seams and burrs, removing rust, etc. The end wheel is suitable for processing at an angle and normal flat. The batch disk is used when working over a large area. Mandrel wheels are used when working with cavities. Flap disc works smoother than conventional sander.
  • Stripping. to remove rust, stubborn dirt. These include disc brushes made of hard metal wire.
  • Polishing. for final polishing of surfaces. These include replaceable polishing cloth, foam and fur attachments. Metal polishing can only be done with a variable speed angle grinder.

Use of discs for other purposes (for example, cutting disc for an angle grinder instead of a grinder) must not.

From metal wire

Disc brushes are made of twisted steel wire. They are designed for rough cleaning work: removing rust, scale, old paint, other types of persistent plaque, burrs, and seams. There are two types of brushes in shape: ring (solid circle), braided (from twisted wire bundles).


Diamond blades for cutting metal are made of steel. Diamond is applied to the cutting edge. This type of wheel cuts and grinds any metal. Advantages. no sparks and no odor, long service life. Disadvantages. high price and the need to take frequent breaks (the diamond cutting wheel is afraid of overheating).

Fabric, fur

To polish the metal, the angle grinder uses various attachments: felt, felt, fur (sheep’s wool), foam. They can be used in combination with polishing paste. A support plate made of plastic or rubber is installed under the attachment on an angle grinder, to which a polishing disc is attached with Velcro.

It is impossible to use discs for stone, concrete, wood for an angle grinder when cutting, processing metal.

Angle grinder discs designed for cutting wood

Chain discs and cutters based on them.

In order to enhance the drawings. click on its surface.

A common power tool when working with metal, an angle grinder. excellently used for processing other materials. Probably put a disc on wood on an angle grinder automatically about safety.

Is it possible to saw wood with such a disc and what types of auxiliary tools for an angle grinder are, let’s figure it out.

There are special cutting discs for wood, created for such work, alas, this is a faster exception. Also, not for every angle grinder such a disc is suitable.
Let’s consider several options.

Such cutting discs are used for cutting boards already 40 mm wide, with the last caution. Rules, non-observance of which lead to injury:

The saw blade has an iron base and a chainsaw chain fixed around the perimeter

  • It is strictly forbidden to remove the protective cover if the diameter of the disc exceeds the dimensions of the casing. your angle grinder cannot be used.
  • The angle grinder must be running at the rpm indicated on the disc. Otherwise, there may be a jumping off of the chain and scattering of its components.
  • Safety glasses and heavy gloves are indispensable. It also does not hurt to wear thick canvas clothes.

The same applies to diamond cutting discs for concrete. For work on sawing wood products, they are not applicable and unsafe. Firstly, the efficiency is very low, especially considering the price of the disc. When. of course, just burn the workpiece.

And in the end. such a disc can always jam in a cut, and you get hit by the body of an angle grinder. Here is a good example of a disc for an angle grinder, with which you can cut wood with extreme care.

The design of the wheel provides protection against jamming by means of side teeth that widen the kerf. The disc has a diameter of 115 mm, and its dimensions allow you to work without removing the protective casing.

What attachments can be used for working with wood

As already mentioned, not every attachment is suitable for this task. Don’t risk using wilds that are not designed for woodworking. Possible attachment options are shown below.

Application of angle grinder for cutting various materials, cutting and grinding wood

If you are trying to understand how an angle grinder can cut wood, then the answer to the myth question is unambiguous: there is an option. But probably they will not do this, tk. people get a lot of injuries specifically from using an angle grinder as a saw for wood, which is correctly called an angle grinder.

At first, this is caused by the unusually high speed of its rotation, for which most of the saw blades are simply not designed. But he directs attention to this when it is necessary to do the work, and there is, as it were, a suitable tool at hand, and an additional compensator ring of a suitable size is applied to the saw blade for wood. In addition, the protective casing is also removed for the convenience of work, which absolutely cannot be done.

However, we will not talk about injuries here, but let’s talk about how to process (including sawing) a tree using an angle grinder, but what about the complexities of working with an angle grinder with a tree species.

Tungsten Carbide Discs

Such attachments have appeared relatively recently and have already become very popular. The reason is that they easily deal with small metal inclusions at high revs.

This is perhaps the only option for a nozzle that will definitely cope with sawing, without any unpleasant nuances.

For your information! Rotarex discs are in great demand, which can be used for sawing wood.

In addition to the actual discs for woodworking, there are other attachments for the angle grinder.

Why is an angle grinder difficult to process wood?

First of all, it should be noted that the high speed of rotation of the disc distinguishes the angle grinder from the circular saw. And even the presence of a compensating ring that comes with the disc does not completely solve the problem. But if your angle grinder has a speed control, then this partly makes the task easier.

You can adjust the tool so that its speed matches the speed of the circular, this will also reduce the risk of injury to the process

But the main difficulty lies not in this, but in the structure of the wood itself, which is often heterogeneous and knotty. In addition to multidirectional fibers, there is resin in the tree, there may be pellets or ingrown wire, which you will not immediately notice. In general, wood is an unpredictable material. During work, you may encounter an unexpected obstacle, and, as a result, a jerk that can knock the tool out of your hands and direct it along a dangerous vector.

If you are thinking of sawing a wood angle grinder in the area, you will have to keep it in a horizontal position. This will make the grip uncomfortable and increase the risk of injury.

What is the danger of working with an angle grinder

Any power tool is potentially dangerous, especially to those who neglect safety and protection measures during work. What’s dangerous about an angle grinder:

  • angle grinder attachments rotate at a very high speed: more than 10 thousand revolutions per minute;
  • most of the rotating disc is not protected by a cover;
  • when cutting the material, small fragments and sawdust are often formed, which fly away at high speed to the sides;
  • a powerful device is quite difficult to hold in your hands, especially if the material for cutting has a complex structure.

When choosing cutting wheels, remember that they are quite fragile and can crack and fly apart during operation.

Advice! When choosing attachments for an angle grinder, pay attention to their condition: they should not have any defects. The slightest unevenness or chipping can lead to sudden destruction of the material during operation.

Advice! If you don’t have experience with an angle grinder, don’t go for a powerful professional model. Better take a household appliance with a disc diameter of up to 125 mm.

What can you do with an angle grinder?

Angle grinder, in common people an angle grinder, is capable of performing many operations.

The design of the angle grinder makes it a rather powerful tool: the basis is an electric motor from 600 to 2700 W with a gearbox, shaft and replaceable nozzles

The more powerful the engine, the higher the professional class of the device. For ease of use, high-quality models are equipped with handles that allow you to securely fix the tool during operation. Household models operate on a regular network. A professional tool requires a three-phase power supply at 380 V.

What operations does an angle grinder perform:

angle grinder can work with different materials: concrete, metal, wood, brick and ceramics, stone, plastics.

For the convenience of work, the angle grinder can be permanently mounted with special fasteners on the working surface. Some models are equipped with adjustable disc rotation speed.

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.

How to cut an angle grinder metal

Cutting metal with an angle grinder is a rather complicated process. Approach him competently.

The working wheel should be selected depending on the thickness of the sheet metal. You will also need to choose a rotation speed that is optimal for the job, and cut strictly according to the drawn lines. Approaching the end of the tile, sink the angle grinder a little so that the cut border does not have a bevel.

You can start the process of cutting corrugated board completely from any edge. If necessary, the cut can also be started from the middle. The only caveat here concerns thin metal. when cutting it, a ragged cut is formed on the back side. To avoid injury and to ensure cleanliness, it is recommended to grind such a cut.

Not sure how to cut pipe angle grinder? Any metal pipe is equal to a sheet of metal and does not require additional skills. The whole difference here lies only in the shape of the product itself.

Cutting reinforced concrete can cause some difficulty. It’s almost the same as cutting metal though. A diamond disc is suitable for these purposes. A little advice. start cutting at a depth of about 1 cm. If there are no problems with your angle grinder, continue the operation. The depth of each subsequent cut should be no more than 1.5 cm.

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.

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.

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.

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.

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.

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.

Useful Tips

There are various models of angle grinder attachments on sale, some of them provide connection of the vacuum cleaner nozzle to the protective cover of the tool. At first glance, the thing is quite convenient, but it is better not to use such devices, since the hose greatly interferes with the work and often only worsens the quality of the seam.

In addition, it is necessary to cut porcelain stoneware, be sure to hold the body of the angle grinder with two hands, while the left hand should rest on the stand or guide rail, and the right hand is directly moving the tool. This method provides not only partial unloading of the hands, but also allows you to more accurately align the position of the cutting disc in the vertical plane.

Regardless of which disc and how to cut the porcelain stoneware, after the completion of the work, the edge must be rubbed with hand or tape emery. In this case, you just need to slightly align the lower edge of the porcelain stoneware and in no case touch the upper front edge with an abrasive, otherwise chips will appear, and the quality of the seam will noticeably deteriorate.

How to cut a porcelain stoneware angle grinder without chips

There are two ways to cut porcelain stoneware tiles. The first is to mark a 1-2 mm deep line on the mowing line in a circle, and then split the granite into two halves, as is done on a tile cutter. The method is quite risky, it requires a good eye and accurate dosing of effort. The advantages include an order of magnitude higher cutting performance. The disadvantages include the unpredictability of the result and a large percentage of rejects.

The second method is the classic cutting of porcelain stoneware to the full thickness of the tile. It turns out a lot of dust, the process takes a long time, but as a result, we get a very high-quality and fairly even cut.

In any case, when using an angle grinder, the seam is uneven. Visually, the line looks perfectly straight, but as soon as the cut plates are turned over and applied to the factory edge or a metal ruler, all the irregularities will immediately become visible. An example of cutting porcelain stoneware with an angle grinder without chips is shown on

How to get rid of dust when cutting porcelain stoneware angle grinder

If the tiles are being cut on a table, then, before starting work, a small piece of loose fabric must be pulled under the cutting line or a polypropylene bag must be hung. In this case, most of the dust flies down from the disk, so the amount of work on cleaning the room is reduced several times.

If you cut porcelain stoneware on a substrate directly on the floor, then the best solution would be to use a regular vacuum cleaner. The tip of the hose is attached along the mowing line of the movement of the angle grinder at a distance of 10-15 cm. It turns out not very convenient, since the nozzle has to be rearranged, but the dust is removed quite effectively. Immediately after completion of work, you need to blow out the angle grinder and collect part of the dust remaining on the surface of the porcelain stoneware.

Direct cutting of porcelain stoneware

It is considered correct to cut a porcelain stoneware slab on a table or workbench. The material is laid on the table top, fixed with clamps with rubber tips. the cut line should be outside the table surface. In this case, it is possible to cut porcelain stoneware with a very small angle of inclination, only 15-20 degrees. The master simply pulls the angle grinder towards himself, only lightly resting his hand on the stand.

Cutting Option Pull Angle Grinder

Why this method is good:

  • The minimum load on the hands, if you need to cut a sufficiently long seam, this will not be difficult to do;
  • the cutting line turns out to be even, it seems that the cutting was carried out not by an angle grinder, but by a tile cutter.

The only disadvantage of this method is that most of the dust escaping from under the disc falls on the floor, and the largest parts fall into the face and hands of the worker. Therefore, it is necessary to cut porcelain stoneware with protective goggles and using devices for collecting dust.

How To Correctly Cut A Highly Raised Angle Grinder

Most beginners and DIYers prefer to cut porcelain stoneware with a tool with a very large angle of inclination relative to the plane of the tile. The angle can be 45-60 °.

The tool can only be lifted high if there is a supporting surface on the cover

In this case, the angle grinder must be held with both hands and at the same time perform small oscillatory movements with the cutting disc. It is as if the porcelain stoneware had to be cut with a hand saw. This is not very convenient, but the method really improves the quality of the cut and prevents the formation of chips.

On the one hand, with such a movement, the angle grinder is easier to control the cutting line, on the other hand, the tool is in an unstable position relative to the markings, which negatively affects the quality of the straightness of the seam.

What disc to cut porcelain stoneware angle grinder

Sawing of porcelain stoneware tiles can be done in two ways, it all depends on the thickness of the material and on how complex the seam is to be cut. Since porcelain stoneware is still not granite, but just an artificial imitation of it, two types of discs can be used for cutting:

  • Vulcanite discs based on synthetic superhard ceramics. With such a circle, you can cut thin grooves, corners, trim the edges. In order to cut expanded clay, an angle grinder over a length of more than 10 cm, they are not suitable, but they are quite suitable for small jobs;
  • Diamond cutting discs. With this tool, you can cut seams of unlimited length. The only drawback of a diamond is the rapid grinding of the cutting edge, which will need to be repaired and cleaned periodically.

The optimum wheel diameter for an angle grinder is 115 mm, in which case the tool is easier to control by holding the body with both hands. For a larger diameter blade, you will need to use a more powerful tool, such as a circular saw.

Diamond cutting wheels in themselves are quite an expensive and capricious tool, therefore they try to do most of the work with vulcanite discs, only the most delicate operations, such as trimming and adjusting the plane, are performed with diamond powder.

In addition, the angle grinder should have a solid edge without a notch or turtle profile for cutting porcelain stoneware. Such a tool cuts well natural granite, rubble stone, but at the slightest attempt to cut porcelain stoneware tiles along the cutting line of the cut, a huge number of enamel chips appear on the front surface.

If there is no particular preference for a well-known brand of cutting disc manufacturer, then it is best to buy discs from leading hand tool manufacturers. Simply put. bought an angle grinder made by Makita, buy cutting discs with attachments manufactured by the same company.

Is it possible to cut the porcelain stoneware angle grinder

Of course, an angle grinder can cut anything you want, with the possible exception of glass or particularly complex ceramic products. But it is not so easy to cut the porcelain stoneware with an angle grinder so as to achieve a perfectly straight cut line.

Of all the reasons that prevent high-quality cutting of porcelain stoneware, the most important ones are distinguished:

  • an angle grinder is a hand tool, and often the material has to be cut, as they say, by weight, as a result, the disk deviates from the cutting plane, this leads to the formation of chips, and sometimes cracking of porcelain stoneware;
  • The cut-off wheel is not selected correctly. In the first experiments, beginners try to cut porcelain stoneware with cut-off vulcanite discs over stone and concrete. With this material, you can cut off a small part of the tile, but most often the result is negative;
  • Incorrect cutting mode or no cooling of the cut line. The desire to cut off faster leads to excessive pressure on the tool, as a result, the circle and the tile itself break, not to mention the fact that the entire line of the cut remains covered with chips and microcracks.

In theory, cutting porcelain stoneware is no more difficult than any other facing material, you just need to choose the right mode, cutting speed, pressing force and correctly choose the cutting tool.

If you cut an angle grinder by weight, then chips must appear

Cutting an angle grinder on the weight is possible only for those who have strong enough hands. If you have to saw at least 20 cm in length, then even experienced and strong craftsmen get tired hands very quickly, the circle begins to deviate from the vertical plane, as a result, the seam begins to wag, and chips appear.

Sole-based cutting

Cutting porcelain stoneware with an angle grinder: how to saw off without chips

Everyone who has had a chance to cut faience, ceramics, porcelain stoneware with a cutting disc knows perfectly well that the problem is not how to cut. Such an operation is not particularly difficult. The problem is learning how to cut a porcelain stoneware angle grinder without chipping. At the same time, control the process at any stage, otherwise the expensive material will go to scrap.

The best way to cut porcelain stoneware is using a guide bar as a support for the angle grinder case

Feature of diamond discs

A special place among all cutting tools is occupied by diamond discs. Their main feature is the presence of diamond coating. The technologies for its application can be different, but the sputtering effect is almost always the same: the disk resource, cutting accuracy and cutting cleanliness increase dramatically. In addition, the list of materials on which you can work is significantly expanding.

For example, the average abrasive disc is extremely inconvenient for cutting ceramics, natural stone or good concrete. Diamond blades handle these materials well.

Basically, discs of this type are designed to work with non-metallic materials, but there are special modifications for metals. However, it should be borne in mind that cutting metal with such discs can only be “in a straight line”. Diamond blades are best suited for:

  • ceramics;
  • glass;
  • all types of stone;
  • brick;
  • concrete and reinforced concrete.

What can be cut with a diamond blade?

The angle grinder (better known as the “angle grinder”) quickly became a popular tool with a very wide range of functions. Various interchangeable discs allow you to solve a wide range of tasks, from direct grinding to cutting a variety of materials.

Are they versatile?

A certain type of diamond blade is better suited for a certain range of tasks. You can, of course, try to work with them as with a universal device, but this will lead to a decrease in efficiency, accelerated wear and increase the risk of injury.

Let’s consider the main types of diamond discs:

Segmented disk.

This option is ideal for dry cutting (without forced water cooling) as the blade is cooled by design features. They are good for cutting concrete, stone (including granite) or brick.

It is important to remember that continuous operation of a segmented disk should not exceed 1.5 minutes, otherwise the intensity of its wear increases dramatically.

Please note: the smaller the segment size, the slower the disk heats up. Reducing the segments also reduces the degree of vibration.

Solid disc.

This type is great for working with ceramics or marble. Due to the solid shape of the disc, an even cut is provided, which allows you to work with decorative materials. On the one hand, a solid disc requires forced cooling (it is widely practiced cutting “in a puddle”), on the other hand, while ensuring high-quality cooling there are no restrictions on the duration of continuous operation.

For working with particularly hard materials, it is recommended to use special discs with oblique slots (splines). They reduce lateral friction by reducing the heating of the disc and helping to remove dust.

Combined disc.

Can be used to cut any non-metallic material, but ceramic tiles should be cut with water and concrete can be cut without cooling. The disadvantage of this type of disks is low efficiency compared to the above options.
