In the decoration and renovation of apartments, the angle grinder is most often used precisely for cutting materials. It is also a great tool for sharpening drills or other chopping or cutting tools such as axes, knives and chisels.

Unable to find the strength to resist the desire to possess them, he began to steal German instruments and every evening he took home at least something. He was very ashamed, but he could not help himself. And not only him. This went on for two weeks. And then the German builders just gave them a box of screwdrivers of various calibers. They took the screwdrivers, but after that they somehow began to ask the authorities one by one to transfer them to other objects. He says that it was unbearable ashamed to work with the Germans after this incident.

How not to use an angle grinder

Angle grinder is a very narrow specialization tool. Everyone knows about it. It’s even silly to write about how and where this tool should not be used. It would hardly occur to you to fight an angle grinder on the barricades or cut a sausage with it. Perhaps in the distant future, when, due to evolution, the boundaries between the upper limbs of people and power tools will disappear, the human brain will swell so much that it will seriously consider one of the auditory openings to go out. Then what then? I don’t know. These thoughts make me sick, and I lose the meaning of the story.

Let’s imagine another situation. You pick up a non-imaginary, real angle grinder, and with evil, decisive steps head towards something or someone. You just need to rummage through your memory and imagine what you would like to cut with it. Have you presented? Now all the mail from the far corners of your memory is sent to your imagination, and your fingers reflexively squeeze an imaginary plastic form with a madly spinning disk. You are confident that an angle grinder at 11,000 rpm will cut anything. You are blinded by the tool’s imaginary versatility. But this is where your carelessness can turn into tragedy and sensitively distort your own fingers. Such a case can undermine your reputation as the owner of "straight hands" and the belief in the omnipotence of the grinders as very cutting, but safe tools for you.

Why cut, chop brick

So why chop or cut building material at all?

Is it really so difficult to choose products of the right size from a wide range?

At a construction site, different situations can arise.

There is not enough half a brick to complete the row, the owner wants to decorate his house with irregular elements.

You can’t just cut it with a hacksaw.

To carry out such ideas, an assembly is needed that can make a brick of any shape.

It is possible to halve the building material without any problems at home, if you have the necessary devices at hand.

If you end up with a product of the right size and shape, you can easily lay the brick in the place intended for it, embody the original design or architectural idea.

How and what to cut a brick

To get two elements of the same or different shapes and sizes from one brick, you have to work hard.

Professionals use specially designed tools to perform such operations, but amateurs will have to be content with what they have at home.

Do not buy expensive equipment just to cut a few elements when building a house ?!

So, here are the tools you can use to process silicate or fireclay bricks:

  • Chisel, combined trowel, pickaxe, hammer;
  • Angle grinder she is an angle grinder;
  • Gas cutter;
  • Hacksaw for metal with a special coating;
  • Jigsaw;
  • Cutting machine;
  • Laser equipment.

The most perfect one for today is the last option.

A compact, mobile laser machine quickly, efficiently and easily cuts not only brick walls, but also a dense, durable monolith, suitable for processing concrete blocks and other building materials.

The principle of operation of the equipment is based on the use of gas-discharge lasers.

Laser systems are quite expensive, so buying them for home use is impractical.

Laser cutting services are provided by construction companies and repair crews.

When performing work, a number of nuances should be taken into account, for example, the presence of reinforcement in the masonry, the type of material, is there access to electricity and water, etc.

Among other popular power tools with which you can cut this building material at home, the first place is given to the angle grinder.

You can also use manual ones, but you will have to tinker with them for a long time.

How and what to cut, chop bricks? Step by step instructions

Sometimes in the process of work it is necessary to cut a brick, how and how to do it we will describe in detail in this article.

Brick is a popular building material that has already established itself as reliable, strong and durable.

Structures made of it are capable of withstanding significant mechanical loads, the negative impact of mechanical factors, and extreme operating conditions.

But it will take a lot of time, money and effort to build a house out of it.

Durable, dense material is not easy to process.

To cut and split it, special hand and electric tools are used, which will be discussed below.

Device and capabilities of an angle grinder

Arranged angle grinder (angle grinder) is quite simple. The electric motor, by means of a bevel gear, transmits rotation to the shaft, on which replaceable nozzles are fixed. The area of ​​use of the angle grinder is extremely wide. It is used for cutting, deburring, roughing, grinding and sharpening. The type of work performed is determined by the functionality of the removable disks. Each angle grinder accessory has its own purpose.

Such a tool is used during construction work, in mechanical and repair shops, during rescue work and in other fields of activity. The angle grinder is indispensable both in everyday life and in production. We also recommend this:

Wood cutting angle grinder

In the absence of special equipment for working with wood, it is allowed to cut wood with an angle grinder. But the thickness of the material cut by the angle grinder should not be more than 4 cm. It is necessary to use special cutting discs and wood cutters recommended for working with the angle grinder.

Hold the cutting tool perpendicular to the work surface. If it is possible to adjust the speed of the angle grinder, set the minimum value. The recommended maximum values ​​must not be exceeded (the corresponding marking is on the disc). When cutting at high speeds, the wood starts to burn, a large amount of smoke is emitted.

It is not recommended to use the button lock during operation in order to be able to turn off the device and minimize possible damage. In order to prevent the tool from jerking at the end of the cut, experts advise first sawing the workpiece along the edges, and only then cutting it.

Can an angle grinder safely cut wood?

There is an angle grinder in almost every home, without it it is difficult to imagine many types of repair work. This multifunctional tool can cut various materials: brick, concrete, metal, porcelain stoneware, etc. The question of whether an angle grinder can cut wood is a matter of controversy.

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

This is perhaps the most widely used tool outside of 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 CUT CORRECTLY 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:

  1. Disc diameter. Remember, the smaller the disc diameter, the more revolutions (higher rotational speed) it can handle, and vice versa.
  2. The choice of a disc depends primarily on the material with which you plan to work and the design features of your instrument.
  3. 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. Let’s get to work.

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

Always remember about such a thing as kickback. This is the most dangerous thing that can happen when working with a grinder. It can occur 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 insulated from sparks during operation. If you need to move the instrument to a different work surface, be sure to turn it off first and then unplug the power cord. The same should be done in the event of a power outage. As soon as there is no electricity, 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, those around you 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 give this special significance, but in vain.

Bulgarian manufacturers advise their consumers the following: The tool should be used in such a way that the course (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 is usually quite long, cut the overhanging edge. Otherwise, if you make a cut in the place between the supports, such an outcome as a jamming of the blade 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, be careful to avoid chipping and unevenness.

It is possible to process rubber with an angle grinder, but not necessary. 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.


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 how to cut 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.


First, let’s talk about the dangers that lie in wait for the master when cutting metal with an angle grinder, namely:

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

Now, here are some 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 course 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 keep your instrument from overheating.

It should also be remembered 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 experienced craftsmen claim that cutting wood with an angle grinder is to be. Our opinion: it is really 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 get under the skin. And this is a direct way to the hospital, because you cannot remove them on your own, plus all this 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 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.

  1. 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. So, do not put additional pressure on the tool, as this will immediately be reflected in the curvature of the cut and spoil your workpiece.
  2. It is very important to choose the right thickness of the circle. There is a simple axiom at work: the thicker the material you work with, the thicker the disc should be. When choosing a tool, consult an expert in the field and pay attention to the marking of the grinding wheel applied to his shirt.


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 fixed.
  • Be sure to install the protective cover.
  • Hold the tool firmly while working.
  • At the end of the work, wait until the disc rotation has stopped completely, place the angle grinder with the disc facing up so as not to damage it, unplug the tool from the mains and check that there is no smoke or signs of fire.

WHAT CANNOT BE CUT with an angle grinder? BASIC ERRORS
