How to cut a brick with an angle grinder without dust

How to make an angle grinder saw concrete without dust

When cutting chinks in walls, trimming bricks, cinder block, concrete and other mineral building materials, a lot of thick dust is generated. If the work is performed on the street, it is still bearable, but here indoors impenetrable dusty curtains collected literally in half a minute. To avoid this, it is worth making a special adapter that allows you to connect a construction vacuum cleaner to the angle grinder. With its help, you can almost completely eliminate the emission of dust into the room.

Cutting of bricks with a special machine

The machine for processing such building materials consists of the following elements:

  • robust metal frame;
  • diamond wheel;
  • power unit;
  • a system for holding the workpiece;
  • water supply system in the working area.

The purchase of this equipment allows you to do the following

  • fast processing of workpieces;
  • to cut products with maximum precision, resulting in an even surface, which is very convenient for further work;
  • increase the safety of work, because the water supply system provides minimal dust formation.

Wetting

The easiest, most affordable option for dust-free work is wetting. That is, the surface with which you will have to work. brick, concrete and so on, before the work must be moistened. And there is no need to use something large, cumbersome, professional. an ordinary sprayer will do for this purpose. In his absence. a plastic bottle with holes made in the lid. Flowers used to be watered with such a device, so it becomes a peculiar fountain. Or a child’s water pistol at all.

The essence of the method is that the spraying should be performed immediately before work, so that the dust gets wet and can not fly away. And since a man by nature has two hands, he will definitely need an assistant. After all, he will work with an angle grinder. So a tandem of two people for this job is ideal. The only inconvenience: instead of dust there will be a dirty slurry. Worth keeping in mind.

How to choose a disk for “angle grinder

Concrete is a tough material, so it is quite difficult to work with it. To perform cutting, most often use an angle grinder (angle grinder). This tool is more commonly known as an “angle grinder”.

A diamond wheel is used as a nozzle. Depending on the design features, they are divided into several varieties:

The first option is a solid base with a segmented edge. Such a disc is low cost, but not too suitable for working with strong materials. We must also take into account that it is used only for dry cutting. The solid disc has a continuous diamond edge, which prevents chipping during operation. Such a tool quickly heats up, so it must be cooled with a continuous stream of water.

Combination or turbo diamond blade is versatile. It withstands maximum load and is even suitable for cutting reinforced concrete.

Before you buy a nozzle of the right type, you need to understand what material you have to work with. Concrete is reinforced by metal bars, which the cutter can bump into in the process. Therefore, if the intended cutting depth is more than 10 cm, stronger discs, i.e. turbines, should be used. Fresh concrete is more abrasive, over time the material hardens, its strength increases. This factor must also be taken into account when choosing a wheel for cutting.

the disc segments are attached to the blade either by silver soldering or by laser welding. The first version is best suited for wet cutting; the second version is only used for dry cutting. When selecting the appropriate diamond wheel, you must also pay attention to its diameter, which must be in line with the parameters of the angle grinder. The rotation speed of the disc is also an important criterion. It is better if it will be higher than the maximum possible index, stated in the technical characteristics of the “angle grinder. This will ensure optimal performance.

Hi there. That it is done by an angle grinder and so it is clear But it’s too much dust, etc. About tile machines also know, but I do not want to buy a machine for 15-20 bricks What else can we saw solid bricks? Maybe somebody used a saber saw? Or a jigsaw

No, you need a smooth saw and then sharpen it with what?? with a bolt cutter?

Ferrari wrote : Maybe someone used a saber saw?

Maybe they sawed with a saber saw.Yeah, it’s a bit expensive, that’s all.

What does that mean?? And how does it cut without splintering? Smooth?

angle grinder without options. You move the handle, you stand in the wind, the dust flies away from you.

Why are you being so sarcastic?? I have an angle grinder with CPS, I have never heard of accidents with a diamond disc that broke off. If you want to walk around in brick dust from head to toe, that’s your right. I’ve been cutting bricks like that for years until I’ve had. Now sawing for myself, I go clean, healthy and happy.

Maybe I do not understand (I am seriously asking), but what is the danger of cutting with a diamond wheel from yourself?? Even if you have a bruiser without CBA, hold it tight, secure the brick properly and alga. No?

When sawing “on itself” the angle grinder, when clamping the disc, flies away from the operator. If your leg (balls, etc., as you choose) is at a disadvantage And recommend your style of work to non-professionals.trying to get rid of the competition.

Enough quarrels, the question was simple: What can be used to saw bricks without much dust?? Yes, I can buy a sabre (and Bosch and makita and milka) and saws for it! I will need it later on in my summer cottage! It’s important for me to saw it all without getting dust in my mouth!

Rasimovich. Lots of information is good, but you need to know how to use it. Have you ever wondered why the side handle has up to five attachment points?? Have you ever seen a furrow cutter?? Read, look and think again.

What kind of solid brick do you have? It may happen that the blade above will not be enough for one. If you are so worried about dust, and there is no vacuum cleaner and the street, then soak the bricks in a basin with water for a few hours, and saw with an angle grinder.

Ferrari. a dust cover, a vacuum cleaner and a wind at your back.

Buy a saber. It’s a beautiful thing. A hard-working man will need it. You should use ceramic brick blades like the ones you used to use. will not live long. They have tiny tips. And a special blade will last for a long time

Is it possible to cut tiles with an angle grinder?

For sawing is more effective to use a tool designed for this purpose. a tile cutter. But if you do not want to buy it “at once”, you can use an angle grinder. Cutting with it takes more time, has a number of specific features that should be taken into account.

For work, you will be suitable for an angle grinder with the most common disc diameter. 125 mm.

Features and problems of work

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 even pieces for further use. Since the brick is fragile, the use of a chipping hammer or peorator is undesirable. So accuracy and form accuracy will be impaired. To get an even pattern, cutting bricks is performed with special tools and auxiliary tools, such as an angle (ruler), a pencil. For your own protection, the builder will need safety glasses and gloves.

There are different ways to cut bricks:

  • Machine cutting:
  • on the machine;
  • on a coping saw.
  • with an angle grinder or chain saw;
  • laser device.
  • With the use of a jigsaw or saw;
  • trowel and hammer;
  • by splitting.

Machine cutting of bricks

An attachment for convenient, safe and fast cutting of bricks by cutters, in half and irregularly shaped. Two types are available: 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:

brick, angle, grinder, dust

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

The main advantages of the machine are:

  • Performing dry and wet cutting with a wheel;
  • High work speed;
  • accuracy of size and shape due to the convenient location when cutting. the person sees the marking.

angle grinder as a cutting tool

When carrying out small amount of work, an angle grinder is used. To cut the material, a device with a 23 cm disc is used. For an angle grinder with a smaller diameter wheel, the brick must be turned over, resulting in a violation of the flatness of the cut side. To avoid defects, the material is secured, and then processed with a grinder in the areas of the cut. With a large circle, an angle grinder is used when cutting a brick wall. To cut bricks at home, the main thing in the application. to hold the working tool correctly: the cutting edge must be perpendicular to the material to be processed.

  • The cutting process should be carried out outside the room because of the large amount of dust. Wear personal safety equipment: goggles and face mask.
  • Keep the tool strictly perpendicular to the marking line.
  • Not to make pressing efforts on the tool.
  • If the diameter of the circle is small, make the cut all around the perimeter, and then remove the excess with a hammer and treat defects and irregularities with a grinder.

Working with a chain saw

Cutting bricks is carried out by a device on the type of standalone circular saw with a more powerful motor almost instantly. But along with high speed the machine is big, so it is hard 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 chamotte bricks for bricklaying ovens and braziers. A respirator is recommended when working with the tool because of a large accumulation of dust.

Circular saw

This tool serves for working with wood, but possible use in sawing bricks and blocks. Material processing on circular saw requires replacement of circular saw blade with reinforced disc K480STZB. Cutting edge must protrude over the table by 7 cm. A ruler is needed to measure the height. Cut the brick should be smoothly, without sudden movements without pressing the tool.

Circular saw

Small-sized stationary equipment, convenient and safe in operation. A variant for cutting facing bricks. Circular saw is used in the processing of wood, replacing the discs for 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 follow safety rules, use PPE.

Laser cutting

Used method when it is necessary to cut a brick or concrete wall. Laser systems work on gas-discharge lasers. But the tool is an expensive equipment when working at home, it requires knowledge and experience. 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;
  • presence of reinforcement, if the wall is cut;
  • accessibility to the power source;
  • water lines for dust suppression.

Stone-cutting machine

Used mainly in large volume construction. The accessories include:

  • metal frame;
  • drive;
  • Cutting unit with a diamond blade;
  • Water supply system in the cutting area;
  • block or brick fastening design.

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

  • making a marking.
  • clamping of work material.
  • Translation of cutting head into working state.
  • Smooth movement along the marking line.

Other tool for cutting material

An easy way to get irregularly shaped brick blocks is by hand cutting. Bricks can be chiseled using a hammer and chisel. To cut with the latter method, lay the brick on a flat surface, chalk a trimmer line at the break-off point. Perpendicular to the line for the trimmer put a chisel, and make a sharp blow with a hammer. The end 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 shred and spoil the block.

  • Handling a brick surface, using jigsaws to cut.
  • Sawing with a hacksaw to give an 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 flatter sides. And a hacksaw or saw can help make shaped cuts, patterns. But for particularly durable products, such as refractory bricks, sawing with such a tool is not suitable. Each method of cutting, chiseling, and sawing has its pros and cons. The choice of electric apparatus, handheld devices, and the type (dry or wet) depends on the end goals.

Good to know

Modern manufacturers offer different models of equipment, so it is not difficult to find a particular model of equipment in the regions (as well as companies or professionals who quickly and perfectly perform the work). But for you need to understand some aspects.

What should be kept in mind when cutting concrete:

  • Wall saws are not used in high-rise panel houses because of the risk of flooding the lower floors with water. Also, the machine is not applicable for work in confined spaces, as needed to do a small amount of cutting.
  • To reduce noise, holes can be cut in parts (at least 6 parts). The cost of work in this case increases and depends on the number of pieces cut.
  • All holes / openings in the supporting structures are made only by certified companies and in strict compliance with the regulations.
  • Legalization of hatches / openings in the bearing walls requires an appeal to the municipal authorities with the provision of a complete set of documents.
brick, angle, grinder, dust

Cutting concrete without dust. This is not an easy task, which can only be achieved in part. One hundred percent get rid of the dust is very difficult, but its quantity can be significantly reduced through the right choice of equipment and nozzles, cutting method, also the use of construction vacuum cleaner and the creation of special devices for collecting dust.

How to glue the brick tiles on the walls yourself

In conclusion, here are a number of recommendations for gluing tiles under the brick on the walls.

Gluing is done on a prepared base. The walls must be cleaned of dirt, mortar residue, dusted and primed.

Marking for laying tiles is most convenient to make a laser level and then conduct the gluing of tiles on the beam. You can also beat off the horizon hydro-level, and with a bubble level to draw lines with a pencil or string.

When gluing tiles from bottom to top, so that the first row does not slide down, under the lower edge of the tiles you can put a plastic smooth starter profile or screw a wooden batten.

The size of horizontal joints can be controlled, using, as a yardstick, a spatula. a plastic or wooden rail. The height of the joint between the tiles is given by the size of the rod, for example, 10-12 mm.

The size of vertical joints, about 8 mm, can be set with a tool such as a stovepipe (mason’s expansion joint for internal joints).

The adhesive mixture is applied to the wall and then to the tiles with a comb, after which the tiles are glued to the wall.
