What to cut bricks with: the tools required, how to work and cutting at an angle

When erecting an object, you can’t do without special technical devices. Modern builders use a variety of equipment, greatly facilitating and speeding up the process. Brick cutting machines and other materials are among the necessary apparatuses at the construction site. They are convenient, lightweight, even beginners without experience can cope with them.

The machine with which bricks are cut fits easily in a car, so that transporting it will not be a hassle. It is also suitable for cutting any natural stone and building material, be it ceramic, concrete, limestone or the like. Indispensable for processing small blocks of raw materials, facing tiles.

A brief description of the equipment

Brick cutting machine household

Brick cutting machines are small-sized devices for quick, convenient and safe cutting of bricks in order to give them the necessary shapes and sizes. The cutting element is a diamond disk with a certain diameter and the best quality. The tool consists of such blocks:

  • Metal frame with cutting disk;
  • Water tank, which is a convenient sprinkler system to minimize the amount of dust;
  • mounting feet;
  • cutting table;
  • Driven motor.

Reliable design allows you to easily cut bricks, blocks of rock and artificial rock. Ideal for working with facing stones, tiles. Relatively low weight and compact dimensions make the device transportable, which is very important for professionals and beginners. Can be transported in the trunk of a passenger car to minimize time and money. That’s why it can be taken to practically any workplace.

Brick cutting machines are produced by many foreign and domestic brands. Manufactured on high-precision equipment using the latest technology. Quality of the tools is always on the appropriate level, meets international standards and generally accepted GOST requirements.

When properly used, the service life can reach dozens of years. Assembled at the factory tools necessarily undergo a series of tests and tests to identify defects. Based on the results, conclusions are drawn on quality, performance, and compliance with the stated parameters. Only then do the machines go on sale.

The main features of machines for cutting bricks:

  • many models can perform two types of cutting at once. dry and wet;
  • high-speed performance;
  • precision cutting. The joints between the bricks are almost invisible.

How and what to cut bricks with?

When performing masonry work or wall cladding, brick cutting is required. The process allows you to get the right parts in unusual shapes. In such a case, you need to know the technology and the rules of sawing, and before that correctly choose a tool. Distinguish between manual devices and whole machines, with which you can get bricks of different shapes and sizes from a standard block.

Features and problems of work

In the construction of a garage, fence, furnace have to manually cut small parts of a brick product. To prevent an increase in material consumption, it is cut with a special tool to obtain flat pieces for later use. Since bricks are brittle, the use of a chipping hammer or peeler is undesirable. In this way, the accuracy and correctness of the shape will be compromised. To get an even sample, cutting bricks is carried out with special tools and auxiliary tools, such as an angle (ruler), pencil. For his own protection, the builder will need protective goggles and gloves.

There are different ways to cut bricks:

  • Hardware:
  • on the machine;
  • on a trimmer saw.
  • Angle grinder or chain saw;
  • With a laser device.
  • With the use of a jigsaw or saw;
  • The bricks are not suitable for use with a trowel and hammer;
  • by splitting.

Machining bricks

Such work can be done with a special machine.

A device for convenient, safe and fast cutting of bricks by cutters, in half and irregularly shaped. Available in two types: industrial and household. The second is better used in home construction, as it is characterized by small size and practicality. The cutting element is a diamond disc of a certain diameter. Tool design:

The device is used to cut bricks of such types as red, refractory, stove, sand-lime brick, trimmer.

The main advantages of the machine are:

  • Dry and wet cutting with a wheel;
  • High speed of work;
  • Accuracy of dimensions and form due to the convenient positioning when cutting. a person sees the marking.

Working algorithm

  • Preparing the workplace and setting up the machine.
  • Marking the product and fixing it on the working surface at the right angle.
  • Bringing the product to the cutting disc.
  • Turning on the power of the machine, select the cutting speed and perform sawing.

angle grinder as a cutting tool

An angle grinder is used when carrying out small amounts of work. A device with a 23 cm disc is used for cutting material. For an angle grinder with a wheel with a smaller diameter brick must be turned, resulting in a violation of the flatness of the cut side. To avoid defects, the material is fixed, and then processed with a grinder in the areas of the cut. With a large wheel an angle grinder is used when cutting a brick wall. To cut the brick at home the most important thing is to hold the working tool correctly: the cutting edge should be perpendicular to the material to be cut.

  • Cutting process should be performed outside the room because of the large amount of dust. Wear personal protective equipment. goggles and face shield.
  • Keep the tool strictly perpendicular to the marking line.
  • Do not apply pressure to the tool.
  • If there is a small diameter of the circle, the cut should be made along the entire perimeter, and then remove the excess with a hammer and treat defects and irregularities with a grinder.

Working with a chain saw

A respirator can help protect your respiratory system from dust that forms when cutting material.

Bricks can be cut almost immediately with a selfcontained circular saw with a more powerful motor. But along with high speed, the device is big, so it is difficult to transport. The large cutting disk in the gasoline cutter resembles the one in an angle grinder. Due to its high power, the tool can saw fireclay bricks for masonry stoves, braziers. A respirator is recommended because of the large accumulation of dust when working with the tool.

Circular saw

This tool is used for woodworking, but can also be used for sawing brick and blocks. Sawing material with a circular saw requires replacing a circular saw blade with a reinforced blade, model K480STZB. Cutting edge should protrude over the table by 7 cm. A ruler will be needed to measure the height. Brick should be cut smoothly, without sudden movements, without pressing the tool.

Mitre saw

Small-sized stationary equipment, convenient and safe in operation. Serves as a variant for cutting facing bricks. Trim saw is used in the processing of wood, replacing the discs on the concrete, performs the function of cutting at any angle, the required dimensions and accuracy. Cutting facing bricks is easy, not demanding much experience. But it is important to observe safety precautions and use PPE.

Laser cutting

Performing work with such a unit is possible with some experience.

The method is used when it is necessary to cut a brick or concrete wall. Laser systems work using discharge lasers. But the tool is an expensive equipment when working at home, requires knowledge and experience in the work. If you cut a brick with this method, you need to take into account the following points:

  • type of brick;
  • The complexity of the cut;
  • The thickness of the product to be cut;
  • The presence of reinforcement, if the wall is cut;
  • Accessibility to power supply;
  • availability of water communications for dust suppression.

Stone-cutting machine

Used mainly in large volume construction. Components include:

  • metal frame;
  • Drive;
  • A cutting block with a diamond blade;
  • water supply system in the cut area;
  • design of block or brick fastening.
  • Making a marking.
  • Fixing the working material.
  • Turning the cutting head into operating position.
  • Smooth movement along the marking line.

Other equipment for cutting the material

An easy way to get irregularly shaped brick blocks is by hand chopping. Bricks can be chiseled using a hammer and chisel. The latter method of cutting requires the brick to be placed on a flat surface, chalked with a trimmer line at the point of chipping. Place a chisel perpendicularly to the trimmer’s fishing line, and strike a sharp blow with a hammer. The result is a split in half. The error in this method is the unevenness of the split, which affects the appearance of the final product. There is also a problem. it is possible to grind and spoil the block.

Technical data of the cutting machine

Proper use of a brick slicer greatly increases the life of the tool. It can be easily placed in a vehicle, and transporting the machine is not much of a hassle. This is important not only for professionals, but also for beginners. The machine can be transported to any construction site.

Factory-assembled tools are tested and tested to detect defects at the machine’s manufacturing stage. The results give an indication of the quality of the device, the performance of which must meet the stated parameters.

Slicing machines have the following features:

Domestic and foreign-made brick cutting tools are on the market. High-precision equipment with the latest technology is used to manufacture the machines. If the quality level of the tool is appropriate, it can rightfully be called a world standard equipment.

Modern brick cutting machines are divided into domestic and industrial devices. They have standard sizes and capacities. Thanks to their guaranteed performance, they can be used in small industrial enterprises, including private construction sites.

Industrial types of equipment that allow you to cut bricks, installed in large factories that produce products in large quantities. Such devices have a large number of functions that allow high-quality processing of construction materials. The main technical characteristics of the models are:

  • voltage 220-380 V;
  • power of 2,2-3,0 kW;
  • Cutting depth is 65-200 mm;
  • cutting length 500-620 mm;
  • The diameter of the cutting disc 300-620 mm;
  • The length of the equipment 950-1225 mm;
  • the height of the machine is 1110-1370 mm;
  • the width of the device is 615-720 mm;
  • machine weight 57-109 kg.

Choose a device for sawing stone or brick should take into account its power, operating mode, the company-manufacturer of the equipment. Devices of unknown or little-known manufacturers can lead to manufacturing defects or machine breakage.

How to use the cutting machine

It is quite easy to work with the equipment. For this you need to prepare the workplace, assemble and install the machine. Before sawing a brick wall or individual items of building material, the surface to be cut must be marked out.

To install the working surface before cutting it must be secured at the right angle. After that, to the marked area is brought to the wheel for cutting. Then you can turn on the power, choose the speed of rotation of the diamond disc, which should result in a smooth cut of the brick.

Despite the fact that the device for cutting bricks has a lot of advantages, it will not always be appropriate to use. Its cost is quite high, so the cutting of the material in small quantities is better left for the angle grinder or circular saw. It is better to cut chamotte bricks with a special gas cutter. Purchase of machines is recommended for professionals who constantly perform similar work in large quantities.

A stationary machine that allows the processing of building materials is an alternative to an angle grinder used for cutting chamotte bricks or facing stone. Any devices for processing workpieces should be supplied to the market with an instruction manual. The work on the machine is carried out in stages:

  • the workpiece is marked out;
  • the workpiece is set at the desired angle;
  • The device’s circle is moved to the workplace;
  • turn on the motor, select the speed of rotation;
  • the cutting element is set in fast motion and the cutting process is carried out.

Refractory bricks can be cut with a machine with a segmented diamond disk. The advantage of using a brick cutting machine is that the brickmaker must adopt a position in which he can carefully observe the cutting process. The material must be processed correctly, so the accuracy and quality of the work must be constantly monitored.

How to get a brick of irregular size or irregular shape

Not long ago masons and craftsmen at home did not consider how to cut bricks for masonry. For many of them the question was solved unambiguously. by cutting. At first glance, the operation does not seem to be very complicated.

Here’s how professionals describe the order of operations when cutting with a combination trowel or pick :

  • take the brick in the left hand;
  • by lightly striking the tool, apply the line for the trimmer chipping on all the edges;
  • Strike the brick with a trowel or pick, keeping the tool perpendicular to the brick face.

The main disadvantages of this method of shaping bricks lie on the surface:

  • processing accuracy leaves much to be desired;
  • the newly formed face is often uneven, and it is desirable to hide it inside the masonry, which is not always possible;
  • the impossibility of cutting at a certain angle.

Fortunately, over time, the construction industry has been enriched by a variety of tools. They not only make labor easier, but also allow you to bring to it convenience and a certain amount of aesthetics. Brick cutting tools have been developed that allow a high degree of precision in the machining of bricks and a high quality of the brick edges.

What tools can be used nowadays, when deciding how and what to saw a brick at home? Home craftsmen and professional masons can use for this:

Converting an angle grinder into a machine tool in steps: 10 assembly steps, wiring diagram to the drawings

To create a machine yourself, you need to choose a design that suits the available skills and capabilities. The easiest way to assemble the machine from blanks created according to the drawings in the profile metalworking shop. Otherwise, it will be necessary to master welding technologies and purchase the necessary equipment.

Below is a step-by-step algorithm for self-assembly with helpful Комментарии и мнения владельцев:

  • After approving the parameters of the project, purchase the necessary materials, blanks, tools and interchangeable attachments. The shopping list is determined on the basis of a prepared set of design documentation. Compliance with current standards in this case is not required. However, it is necessary to specify all the important data, as in the above examples.
  • Cut blanks for the power frame. The table is made of sheet steel of at least 5 mm thickness.
  • Attach cross shaft to the pendulum lever by welding. When creating this assembly carefully control the perpendicularity of the parts.
  • For fixing the angle grinder is suitable gripper in the form of the letter “U”. In its sides make a hole for bolts. With these fasteners the hand-held tool is rigidly connected to the base frame. Select a sufficiently strong part of the angle grinder body.
  • Additional fixation is achieved by means of a metal clamp. All of the above fasteners are made rigid to improve accuracy.
  • The bearings of the swivel head are pressed in. Use thick walled steel pipe of appropriate inner diameter instead of the typical factory-made assemblies.
  • Attach the complete assemblies to the axle on both sides.
  • Attach the pendulum to the platform by welding. In order not to damage the bearings, it is recommended to limit the temperature increase. Use a cloth soaked in water for cooling.
  • Weld the block with a fixture for the angle grinder. Set in place the angle grinder, protective equipment, return spring.
  • Check the quality of assembly, fixing reliability and pendulum functionality. Wire up machine, test run it first in no-load and then in service. Cut a groove in the table with an appropriate width disc.

It is also useful for quick emergency shutoff. One or more buttons to break the appropriate chain are installed in a convenient location on the machine body. Foot-operated switches are also used.

Features and operating problems

In the construction of a garage, a fence, an oven, you have to manually cut small parts of a brick product. To prevent an increase in material consumption, it is cut with a special tool to obtain flat pieces for later use. Since bricks are brittle, the use of a jackhammer or peorator is undesirable. So the accuracy and correctness of the form will be compromised. To get an even pattern, cutting bricks is done with special tools and auxiliary tools such as an angle (ruler), pencil. For your own protection, the builder will need protective goggles and gloves.

There are different ways to cut bricks:

Circular saw

This tool is used for woodworking, but can also be used for sawing brick and blocks. Material processed on a circular saw requires replacing wheel with a reinforced disk of K480STZB model. The cutting edge should protrude 7 cm above the table. A ruler to measure height is needed here. Always cut the brick smoothly, without sudden movements and without exerting any pressure on the tool.

Trimmer saw

Small stationary tool that is easy and safe to operate. Serves as a variant for cutting facing brick. Trimming saw is used in the processing of wood, replacing the discs for concrete, performs the function of cutting at any angle, the required size and accuracy. Cutting facing brick is made with ease, does not require much experience. But it is important to observe safety precautions, to use PPE.

Laser cutting

The method is used when it is necessary to cut a brick or concrete wall. Laser systems work with gas-discharge lasers. But the tool is an expensive equipment when working at home, requires knowledge and experience in the work. If you cut a brick with this method, you need to take into account the following points:

  • type of brick;
  • complexity of the cut;
  • The thickness of the product to be cut;
  • The presence of reinforcement, if a wall is cut;
  • Availability to a power source;
  • presence of water lines for dust suppression.

Stone-cutting machine

Used mainly in large volume construction. Accessories include:

  • metal frame;
  • drive;
  • cutting block with a diamond blade
  • The water supply system in the area of the cut;
  • block or brick fixing structure.

After the material is fixed, it can be cut with a machine.

  • Making markings.
  • Fixing the working material.
  • Turning the cutting head into working condition.
  • Smooth movement along the marking line.

Another tool for slicing the material

An easy way to get irregularly shaped brick blocks is by hand chopping. Brick can be chiseled using a hammer and chisel. For cutting in the latter method it is necessary to put a brick on a flat surface, put a chalk line for a trimmer in the place of a break away. Perpendicular to the trimmer line put the chisel, and make a sharp blow with the hammer. The end result is a split in half. The error in this method is unevenness of the split, which affects the appearance of the final product. There is also a problem. you can shred and ruin the block.

  • Machining the brick surface, using jigsaws to cut.
  • Sawing with a hacksaw to give the original relief, for example, when you need to process a decorative brick.

An electric jigsaw is used to speed up the sawing process, but also to get more even sides. A hacksaw or saw will help to perform shaped cuts, patterns. But for particularly durable products, such as fire bricks, sawing with such a tool is not suitable. Each method of cutting, chiseling, sawing has its advantages and disadvantages. The choice of electric machines, handheld devices, and the type (dry or wet) of equipment depends on the end goals.

How and what to cut bricks with?

For a bricklayer with experience, cutting bricks is no problem. But no matter how skillful a craftsman is, to make such a cut perfectly accurate and even, it will take a lot of time, unless you use a special tool. This is often required when remodeling, installing built-in furniture, safes, engineering equipment.

fixture, angle, grinder, cutting, bricks

Our task is to cut a through hole by ourselves, as carefully as possible. We will need an angle grinder (angle grinder) with a disk of 230 mm, as well as a powerful drill, and even better peorator. We mark the future opening, with a pencil or marker we draw lines on the partition along which we will cut the brick. In the corners we drill through holes, making them strictly perpendicular to the plane of masonry.

Now the turn of the angle grinder. If the partition is half a brick, then, taking into account the plaster, its thickness. about 14-16 cm. The cutting disc has a diameter of 230 mm, and the cut will turn out good at a depth of 7-8 cm. In this case, it would be correct to cut with an angle grinder on both sides of the opening. Marking on the underside is not difficult to do by simply joining the holes with lines. Break through the cut block with a sledgehammer. If the design is strong, it can be further divided into elements of approximately 20×40 cm. When you hit the product will break along the kerfs.

How to cut tiles with an angle grinder without the additional cost of special devices

If you have an angle grinder at home, you can do without a tile cutter. But how to cut a tile with an angle grinder to get a neat cut, not everyone knows. And you need to start by selecting the discs that will help turn your device into a tile cutter.

Selecting the right discs

For cutting tiles, steel diamond-coated dry cutters or stone circles are suitable. Diamond discs can be chosen as segmented or solid, but for the duration and efficiency of the process it is more important the intensity of the grinding.

fixture, angle, grinder, cutting, bricks

Segmented diamond wheel has uniform, directed from the edge to the center of the cuts, as if dividing the circumference into segments. Ceramic tiles can be cut with this disc, as well as natural stone and porcelain stoneware. Slots in the workpiece are effectively air-cooled. it helps to avoid overheating and prolongs life time of the dry cutter. Only when cutting porcelain tiles with an angle grinder and segmented wheels are more prone to chips.

If you need to cut tile without leaving jagged edges, you should take a solid disc. When using them, you can not only avoid chipping, but also treat the cut edge. This tool is ideal for stone work. The solid surface avoids unnecessary detonation during the process, and the slices can be cut quickly and evenly.

For an angle grinder, you can pick up a stone wheel. They are cheaper than diamond blades, but they have a shorter service life. This disc gradually wears out during operation, and must be replaced with a new one. For example, cutting brick with an angle grinder can be accompanied by not only a lot of dust, but also a 2-3-fold change of the working wheel. But you don’t have to worry about jagged edges and chipping. we use stone disks to cut material smoothly and evenly. True, the abrasion of the wheel can damage the edge, so you need to monitor its condition.

Modern industry offers a special device for working with stone, ceramic granite, concrete and marble. it is an attachment to the angle grinder slider mechanic. Its versatility will help to cope with tile cutting even for beginners. The slider will help you get a piece of the desired size with even edges and no chips. It is much easier to make curved cuts and holes.

Construction of a machine for cutting bricks

The design of the machine externally resembles a circular saw, only in a smaller size. Of course, there are differences in the attachment of the cutting disc.

When designing a machine, you can use existing diagrams and drawings with exact dimensions.

Or you can create something fundamentally different from the others, according to your own ideas and calculations. The main thing is that the result obtained will do the job and is safe to maintain.

  • The disk itself on the engine, or a fixed angle grinder.
  • The carriage, that is, the moving part on which the brick is placed for cutting.
  • A fixed base to which the entire machine construction is attached.

You can attach feet to the machine, or you can fix it on any convenient place (table, workbench, etc.).

In addition, some craftsmen prefer to work on the machine using water. To prevent the dispersion of brick dust all over the room.

If you think the same, you should think in advance about the mechanisms of water supply to the place of sawing.

Alternative variants

What to do when you need a machine for cutting bricks here and now? That is, there is no time to make it, and it will be needed for a short time.

There is, of course, a way out. It is possible to apply for the sawing of construction material, all the same circular saw, mentioned above.

Naturally, you can not do without some changes in the design, but believe me, they are not critical.

It is only necessary to remove the sawing iron disk from the circular saw. Then, instead of it, install an abrasive, fiberglass-reinforced wheel.

It is mostly used for cutting steel and is sold at any hardware store. The marking K480STZB is preferable, but another will do, at your discretion.

The cutting part of the wheel should protrude above the surface of the circular saw table at least 70 millimeters. Taking into account that the standard brick is 65 millimeters in thickness.

But too big a circle is not recommended. Because it starts to “wiggle” during work, i.e. it bends from side to side.

Technical characteristics of the cutting machine

Proper use of the brick cutter greatly extends the life of the tool. It can be easily placed in a car, and transporting the machine is not much of a hassle. This is important not only for professionals, but also for beginners. You can transport the machine to any construction site.

Tests and tests of tools assembled in the factory can detect defects at the stage of machine manufacturing. The results allow us to judge about the quality of the device, the performance of which should meet the declared parameters.

Cutting machines have the following features:

Domestic and foreign-made brick cutting tools are available on the market. High-precision equipment with the latest technology is used to manufacture the machines. If the quality level of the tool is appropriate, it can rightfully be called a world standard equipment.

Modern brick cutting machines are divided into domestic and industrial devices. They have standard sizes and capacities. Thanks to their guaranteed performance, they can be used in small industrial plants, including private construction sites.

  • cutting depth 65-200 mm;
  • cutting length 500-620 mm;
  • cutting disc diameter 300-620 mm;
  • length of the equipment 950-1225 mm;
  • the height of the machine 1110-1370 mm;
  • device width 615-720 mm;
  • machine weight 57-109 kg.

You should choose a device for sawing stone or bricks, taking into account its power, operating mode, the company-manufacturer of the equipment. Devices of unknown or little-known manufacturers can lead to defects in the production or breakdown of the unit.

Specialized machinery

By specialized equipment I mean machines designed for even cutting. They are mostly homemade. Their purpose is to hold the angle grinder at the required angle with the possibility of free vertical movement.

You also need to fix the brick itself, because only in this way can we achieve the most even cut in the right place. If you don’t secure the stone properly, be prepared for it to fly out and damage anything that may be around the installation.
