Careful cutting of bricks

When it comes to masonry work, there are times when whole bricks are not suitable and when the surfaces of chipped bricks are not smooth enough. In this case, cutting bricks is the best option. When making window or door apertures in existing walls you have to cut bricks.

In order for masonry bricks to turn out even, sometimes bricks will need to be cut.

How to Cut Bricks | Masonry

Necessary tools

Brick cutting is done with an angle grinder, a stonecutter or a petrol cutter. You will also need an angle grinder and a construction pencil.

Making blanks

Brick cutting with an angle grinder is necessary for small batch production. For single customer or construction crews it is uneconomical to buy specialized equipment and they have to use more universal equipment.

For cutting bricks with an angle grinder you need a power tool with a diameter of 230 mm.

It is best to use diamond discs to cut bricks with an angle grinder.

When using an angle grinder under the 180th circle cut the brick to its full thickness will not work, you have to turn it over, which significantly reduces productivity and convenience of work, and an even cut for two passes will not get.

angle grinder for cutting bricks should choose quite powerful. For long life of the tool and a comfortable speed of work you need an angle grinder power of about 2 kW or more. Too powerful machines are not desirable, t. к. they, as a rule, have a sufficiently large mass and dimensions, which contributes to rapid fatigue when working with angle grinder and reduces the overall comfort of operation. It is convenient to work on surfaces with a 125 mm angle grinder.

While using an angle grinder, don’t forget about safety. Safety glasses must be worn.

There are two basic types of stone grinding wheels: abrasive and diamond. Perhaps the only advantage of the standard grinding wheel can be considered its relative cheapness. It is a relative cheapness, because. к. Conventional abrasive wheels are subject to rapid wear and must be replaced frequently. They are also inconvenient to work with, because the grinding of such a wheel always reduces its diameter, and to a full depth it cuts only at the beginning of use. Abrasive wheels from different manufacturers can vary greatly in quality and service life. As a rule, a good abrasive stone wheel is double-reinforced and 2.5-3 mm thick. It is dangerous to work with a grinding wheel, because. к. It is more prone to warping and breaking.

Diamond wheel is preferable as it keeps constant diameter while working. One good quality diamond wheel can outlast dozens of ordinary grinding wheels. The diamond wheel has a strong steel base, so there is negligible possibility of breaking.

Brick chopping and breaking: a. correct chopping transversely; b. incorrect chopping transversely; c. chopping lengthwise; d. working position for chopping; e. working position for cutting.

There are several types of these wheels. The simplest solid-edged wheels are cheaper than the others, but have significant disadvantages. They become very hot during operation and can cause accidental wear of the disc. To avoid this, work breaks must be taken. These discs have the shortest service life. The virtue of the solid disc edge is a high quality cut surface without burrs and pitting.

The most common diamond wheels are segment grinding wheels. Their cutting edge is divided into individual radial kerfs. This design allows efficient sludge removal and ventilation of the cutting zone. It is a good choice if you want to cut bricks with an angle grinder. They are typically used for dry cutting. When water is applied, the segment grooves become blocked by wet cutting products which impairs the performance of the disc.

How to Easily Cut Bricks With a Portable Angle Grinder

The optimum choice is still the disc with a turbine edge. It has a serrated surface that gives the blade greater strength and rigidity. The spiral arrangement of the teeth on the disc edge creates a centrifugal pump effect, which is the best way to remove wet or dry sludge. Discs of this design are the most durable and cut all types of brick and masonry stones.

Before you cut the brick with an angle grinder, you must first make a marking. This is done with a pencil and a square. The thickness of the disc and the play on the angle grinder’s spindle must be taken into account. If you just run the line to the right size, you probably won’t get anything. The brick cut will be 1.5 to 2 mm shorter than the required size.

For cutting bricks it is best to use diamond discs with a turbine edge. They are well suited for work with particularly tough materials.

Cutting blanks

Brick cutting with an angle grinder is necessary for small batch production. For singles or teams of builders, it is unprofitable to buy specialized equipment and have to use a more versatile one.

To cut bricks with an angle grinder you need a power tool with a diameter of 230 mm.

For cutting brick with an angle grinder it is better to use diamond discs.

When using an angle grinder under the 180th circle to cut the brick to its full thickness will not work, you will have to turn it upside down, which significantly reduces the performance and convenience of work, and an even cut for two passes will not get.

Angle grinder for cutting bricks should choose a powerful enough. For long life of the tool and a comfortable speed of work you need an angle grinder with power of about 2 kW or more. too powerful machines are not desirable, because. к. they tend to have a fairly large mass and dimensions, which contributes to rapid fatigue during the work of the angle grinder and reduces the overall comfort of operation. Finishing of surfaces is convenient to produce an angle grinder at 125 mm.

During the use of angle grinder, do not forget about safety. Wear safety glasses under all circumstances.

Turbid edged diamond blades are best for cutting bricks. They are well suited for particularly tough materials.

Cutting bricks with an angle grinder is tricky, and requires a certain skill, t. к. The disc should be kept absolutely vertical and should not be tilted until the process is finished. In an inexperienced hand, the tool “walks” on the weight. If you have to cut bricks with an angle grinder for the first time, it is better to try and practice first. Suitable inexpensive bricks for rough masonry, or find a few used. You can also make a pre-cut of a few mm depth. It helps a little to center the wheel during the basic cutting and is more visible in conditions where the pencil line is quickly covered with sludge. Put another one under the brick you are cutting. That way you save your disk and it’s easier to hold.

If it so happens that at the moment there is no large angle grinder, and you need to cut a brick, you can make a bar on the perimeter with a small angle grinder. Then it remains only to carefully repel the surplus and grind the cut with the same machine.

Sometimes, to eliminate displacement of the workpiece in the process of cutting, a brick clamped in a special device where the brick is fixed from the vertical and lateral displacements.

Arrangement of openings

Cutting bricks with an angle grinder is sometimes necessary when making apertures in the walls. If a brick is not placed on the edge, the diameter of the circle will certainly not be enough to do the job in one pass. In this case, mark the opening on the wall on one side and make through holes in the corners with a grinder, which will allow you to transfer the markings without displacement on the opposite side.

Cut bricks according to the marking on both sides of the opening. In order to avoid jamming the circle, the bottom of the opening is cut first. If the depth of cut is insufficient even with a double-sided cut, the remainder will have to be chiseled out. But even so the opening will be smoother and more accurate than if you make it without cutting it at all. Labor costs are reduced at times.

How and what to cut bricks?

For a bricklayer with experience cutting bricks is not a problem. But no matter how skillful the master is, to make such a cut perfectly accurate and even, it will take a lot of time, if you do not use a special tool. This is often required when remodeling, installing built-in furniture, safes, engineering equipment.

How To Cut A Brick Wall Opening. DIY At Bunnings

Our task is to cut a through hole by ourselves, as accurately 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 out the future opening, with a pencil or marker we draw on the partition of the scythe scaffold, by which we will cut the brick. In the corners we drill through cavities, 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 is 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 from the underside is not difficult to do on the drilled holes, simply connecting them with lines. Break through the cut block with a sledgehammer. If the structure is strong, it can be additionally split into elements of about 20×40 cm. When struck, the product will break along the kerfs.

Quite recently, masons and craftsmen at home did not think about what to cut bricks for masonry. For many of them the question was solved unambiguously. by cutting. At first glance, the operation is not very complicated.

Here’s how professionals describe the order of operations performed when chopping with a combination trowel or brush :

  • Take the brick in the left hand;
  • easily striking with the tool, apply a line of chipping on all the facets;
  • Strike sharply with a trowel or pick, positioning the tool so that it is perpendicular to the face of the brick.

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

  • The accuracy of processing 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 with a variety of tools. They not only make work easier, but also allow you to bring to it convenience and a certain amount of aesthetics. The new brick-cutting tool ensures high cutting accuracy and a high quality of cut surfaces.

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:

Overview of tools for cutting bricks:

Cutting with a chainsaw

The chain of the concrete cutter has a special diamond coating. Using a concrete cutter to cut solid bricks is impractical.

It is not very convenient to cut solid brick with a chain saw. This tool is bulky and heavy. The concrete cutter with a wheel resembles a large angle grinder, but with a powerful gasoline engine. Chainsaw with chain is similar to a chainsaw, but all elements are more powerful and designed to take heavy loads. The chain is made with special technology and is diamond-coated. just like the wheels.

Benzor cutters are good at making openings and demolishing brick walls. Arrangement of an opening with a gasoline cutter with a wheel is similar to the execution of works with an angle grinder.

When using a chain cutter the task gets easier as the cutting depth is deep enough to cut through walls of any thickness.

Almost all chain saws have a forced feed of water to help protect your eyes and lungs from dust.

Chisel tool

The first tool is called a “pick. They come in completely different sizes and are used in different ways. The reverse side of the hammer, which was mentioned in the previous paragraph, performs exactly these functions, but such a chancing tool alone will bring an order of magnitude more benefit than tied to the other.

It should be used accurately, with light but precise strokes on the desired area. The force to be applied should not tear the brick to shreds, remember that.

The second gadget I would recommend are special chisels for chopping bricks. Their size and shape allow you to perform the task with millimeter accuracy.

The disadvantage of these techniques is that it is very difficult to make a corner chipping, and even if it succeeds, its evenness will obviously be lame. Consequently, a normal joint will not work, and all the aesthetics will be lost in the unknown.

There was a grandfather I knew, who was considered the best of the best. He himself had laid out a two-story oven in three days. And everything was even, and quality. Once I had to work with it, and of course, when it came to the end of the side, it was necessary to break off a piece of. For this, my grandfather had a special little homemade pick.

I suggested using a cutting tool, to which I heard some insulting remarks. In the end, at the end of the work, the customer was stunned at how much material had been spoiled. I told it all to the point that be prepared for a huge amount of waste material, unless of course you understand that using newer methods is more efficient.

An ordinary hacksaw or a saw for bricks is no good. It would quickly blunt, and it would take too much time for each stone. Therefore, if you just need to reduce the size of the brick in a straight line mowing line, use the method of cutting.

You will need a pencil, a construction angle, and a small construction pick.

To split, choose bricks without cracks or other visible defects. On them, using an angle piece, they mark out all the facets, and with a sharp tool, make a groove on one of them.

Then turn the brick with the groove downwards, take it in the left hand so that the large half is in it, and with a sharp and strong blow of the pick on the marking split it.

The tool must be perfectly perpendicular to the brick surface. When you strike at an angle the bevel becomes jagged. This is also the case when the brickmaker holds the brick by its smaller half or at the point of splitting.

The pictures show the sequence of work. The last picture is an example of incorrect gripping and striking

Please note. This method is suitable for well-fired bricks. If it is not of the best quality, grooves 5 mm deep have to be made on all sides.

Experienced craftsmen make do with a single pick and do not make grooves. But if this is the first time you are trying to cut bricks with your own hands, it is better to do everything by the rules.

Tip. If you can’t leave it inside the masonry, you can gently hammer away the protruding parts and rub the cut against another brick.

Cutting bricks and all about it

Not everyone has a machine for cutting bricks. Small industries and individuals do not have extensive technical capabilities in the work as large. You have to work a lot by hand. If this is construction, it is not profitable for private brigades or single specialists to invest in expensive equipment. They use experience that gets the job done well and on time and do it all themselves. Today we will tell you what to cut bricks with and how to do it properly.

What to cut a brick: the necessary tools, carrying out the work and cutting at an angle

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

Brick cutting machine fits easily in the car, so that transporting it is not a problem. It is also suitable for cutting any natural stone and building material, whether it is ceramic, concrete, limestone or the like. Indispensable for processing small blocks of raw materials, facing tiles.
