ways to saw with an angle grinder without dust?
From this article you will learn how to saw with an angle grinder without dust, a total of 3 simple ways are described.
When sawing with an angle grinder, concrete, brick, stone or tile generates a lot of dust.
Dust not only pollutes the room or the work area, but also has a detrimental effect on human health.
Besides, it is much more difficult and inconvenient to work in dust, t.к. It is hard to breathe and you can’t see anything.
To produce dust-free work, you can use three reliable ways.
It is necessary to attach a small door hinge from below to the protective hood of the angle grinder. To do this, one hole is made in each hinge and guard.
Then they are screwed together with a screw and nut. It is important to try on the diamond disc right away, so that it does not rub against the screw head. The hole on the hood of the angle grinder will not affect its operation in the future, so it can be drilled without fear.
To the second part of the hinge is screwed on two self-tapping screws on metal. They hold well in the plastic. The elbow is positioned with the socket with a sealing rubber towards the power button of the angle grinder. The attachment of the knee and the hinge is made against the line of the beginning of its bend.
Next, you need to start the angle grinder and press the knee to the cutting disc so it selects a slot under itself. Now, when cutting mineral materials, all dust will fly straight into the knee, not spraying to the sides. This adapter works best with a segmented diamond disk (with slots). A normal one-piece disk can give a small amount of dust flying to the sides.
Then you need to attach a vacuum cleaner to the elbow. For this purpose a rubber reduction is inserted into the socket. The inner diameter of the adapter is matched to the thickness of the grinder pipe.
This adapter is as effective as the more expensive specialised shrouds, but at a fraction of the cost. Because the knee is screwed down with one screw, it can be pushed back when needed instead of being removed when it gets in the way during deep cutting.
Such a tool is ideal for the 125 mm angle grinder. For a more massive tool, the design needs to be improved to not support the knee and hold the angle grinder with both hands. It is desirable to connect a vacuum cleaner to the angle grinder through the cyclone to prolong its life.
You need to attach a small door hinge from below to the safety guard of the angle grinder. To do this, one hole is made in each hinge and shroud.
Then they are twisted together with a screw and nut. It is important to try on the diamond disc immediately so it does not rub against the screw head. The hole on the hood of the angle grinder will not affect its work in the future, so it can be drilled without fear.
Screw the knee to the second part of the hinge with 2 self-tapping metal screws. They are held well in the plastic. The knee is located with the socket with a sealing rubber in the direction of the button on the angle grinder. Fastening of the knee and the loop is made against the line of the beginning of his bend.
Next, you need to start the angle grinder and press the elbow to the cutting disk so that it selects a slot under itself. Now when you cut mineral materials all dust will fly straight into the knee, not spraying to the sides. This adapter works best with segmented diamond discs (with slots). A normal solid disc can give a small dust dispersion to the sides.
Then attach the vacuum cleaner to the knee. For this purpose a rubber reducer is inserted into the pipe socket. Inner diameter of the adapter adjusted to the thickness of the pipe of the vacuum cleaner.
Such an adapter works as effectively as specialized expensive covers, but costs pennies. Since the knee is screwed down with one screw, it can be pushed back when needed and not removed when it gets in the way of making deep cuts.
Such a tool is ideal for a 125 mm angle grinder. For a more massive tool, the design must be improved to not support the knee and hold the angle grinder with both hands. It is advisable to connect a vacuum cleaner to the angle grinder via a cyclone to extend its service life.
How to cut tiles and porcelain tiles without dust and chips with an angle grinder at home
Every master who is engaged in facing walls with ceramic tiles, knows that it is impossible to lay it without undercutting. This is true both when tiling walls and when laying porcelain tiles on the floor. But not everyone knows that you can use an ordinary angle grinder (angle grinder) for trimming. Consider how to perform this operation correctly and without chipping.
What kind of discs are used for cutting tiles
For cutting ceramics you need special discs, which can be stone or metal with a diamond coating. Stone is rarely used, as it is rather thick and quickly worn down, and during operation it is very dusty. The cost of stone discs is many times less than metal discs, but specialists prefer to work with the latter.
Preferably use a flattened disc for cutting ceramics. There is a time limit when using such discs: do not cut continuously for more than 1 to 1.5 minutes. Then allow to cool down while the angle grinder is idling.
Segmented discs are designed for cutting paving stone, porcelain stoneware, natural stone or concrete.
Segments are designed for better cooling of the tool during operation.
To cut tiles with an angle grinder, you need to master three cutting directions.
It’s easy to learn, and the trimmer line cuts cleanly and without splinters. When performing the work, the tile is securely fixed on a flat surface, marked with a pencil or marker. The cut off part should hang down freely from the table. The cutting tool is positioned
at right angles to the workpiece. Carefully, without jerking, slowly guide the angle grinder along the marked line. Move the tool towards yourself so that the marked trimmer line is visible.
At an angle of 45
It is often necessary to make a joint, and this involves cutting the material at an angle of forty-five degrees. This angle can only be achieved with intensive training. But you can use this technique: first cut off the workpiece in a straight line, and then carefully work the edge at the desired angle with a disc, emery or sharpening stone.
A curved cutout
It is often necessary to cut a round hole in a tile. Perform the work properly with an angle grinder can be done with some skill. To do this, mark out a hole on the workpiece and trace the line for the trimmer with a felt-tip pen, mark the center of the circle. Begin to cut at a slight angle, slowly, on the inside of the line, gradually passing around the entire circumference. Then cut through the sectors, take them out one by one, undercutting the ceramic if necessary. Finish the edges with a file, obtaining an even circle. Such processing is called dry-cutting.
These holes are usually cut for drains or vents.
When performing shaped workpiece processing, it is easiest to make rectangular cutouts. For even, splinter-free cuts, change the cutting wheel regularly. If you use segmented discs, the cut line is sure to be chipped.
How to get rid of dust when cutting tiles
Cutting tiles with an angle grinder is not very difficult, but it causes a lot of dust. There are techniques that can reduce dust formation. Specialists use special tile cutters for this purpose, but it is not reasonable to buy them for one-time work because of their high cost. This is why craftsmen do things differently when working on a part. Firstly the glaze layer is cut through. it is almost dust-free, the main dust appears when the fired clay layer is processed. Then it remains to carefully break the ceramic tile and process the edges with an abrasive material.
A common way to get rid of dust is to wet the workpiece. This is done by constantly pouring water into the work area with the diamond wheel. It is necessary after each pass of the tool to fill the seam with water or install a special device for water supply to the work area. This device is fixed directly on the protective hood of the angle grinder. As a result, the workpiece is processed without dust.
Cutting porcelain stoneware
When performing repairs, not only walls are clad. On floors in the bathroom and toilet lay porcelain tiles. an artificial material that replaces the granite and marble. Its cost is many times less than natural, but on the parameters of hardness and abrasion porcelain surpasses them. Recently it has become widespread. It can also be cut with an angle grinder.
To do this, you need to know the basic methods of processing the material at home.
- It is necessary to choose the correct cutting tool. On it should be written for what it is used: porcelain stoneware, hard ceramic, etc.п.
- To have fewer chips, choose a disc with a solid cutting edge. The thickness should be minimal.
- Choose a cutting wheel with a high diamond coating height.
- angle grinder should have a speed controller.
After selecting the tool prepare the workplace and begin to cut porcelain tiles with an angle grinder. To do this you must perform the following consecutive steps.
- Place the material on a flat surface, placing a thin foam pad or similar material under it.
- Securely fasten the tile to the surface using clamps.
- To reduce chipping, apply masking tape and make a marking on which to cut off the excess part.
- Prepare a vacuum cleaner to remove dust.
- It is necessary to cut from the front side, moving the grinder in the direction from yourself.
- It is advisable not to saw along the marked line, but a little to the side. This is done for subsequent grinding of the porcelain tile end to remove the irregularities and chips.
Following these simple recommendations, you can own hands qualitatively prisyat floor tiles.
Cut the paving stone with an angle grinder
Having a private home, there is a need to lay paving tiles or paving stones, which must be cut to size. To do this, too, use a universal device, which is available in almost every home. an angle grinder.
Non-dusty methods of work with an angle grinder
An important rule that in no case can be neglected if you are dealing with an angle grinder. the use of personal protective equipment (PPE). Depending on what material you will work with, choose a respirator or half mask with interchangeable filters. Also wear safety glasses and close-fitting gloves. In the long process of using the angle grinder will not be out of place and headphones to protect your hearing.
Water versus dust
The first way to get rid of dust is to spray the work surface with water. For this you need an ordinary sprayer. If you do not have it on hand, remember your childhood and make a squirt out of a plastic bottle, puncturing the small holes in the lid. Remember: water must not spill too much and not get into the tool.
To work with such a wet method is necessary for two people. One person is wetting the surface, while the other is sawing. These actions must be performed simultaneously. Dirt, of course, will be a lot: the crumbly material when mixed with water immediately turns into a slurry. But it’s still much better than the dust. Easier to clean and safer for your health.
The wet cutting process can also be done alone. In that case, you will need an angle grinder for concrete, the casing of which is provided with a water supply. You can buy ready-made equipment. For example, a housing into which water is pumped by an electric pump that comes with. A more budget variant is to make such a device by yourself.
It is worth bearing in mind that for the wet method to the angle grinder must be installed cutting wheel. Solid diamond disks are suitable. They are used for wet cutting of concrete, ceramics, marble. Turbo wheels with a serrated edge are also used.
The water method is considered the least time-consuming. Among its other advantages:
The only disadvantage of this method can be called the transformation of dust into a wet slurry, which will spill over the entire work surface.
Using a vacuum cleaner
The dry method involves the use of a vacuum cleaner instead of spraying. In this case, in the process of work you will have to take breaks: the equipment quickly heats up. From time to time the angle grinder needs to be turned off to let the tool cool down.
Cutting installed marble tile with angle grinder indoor without dust
This technique is usually used when a wet cut is not possible. For example, in rooms with already laid utilities.
For dust extraction, you can buy special attachments for an angle grinder. They are a protective cover with an adapter for connecting a vacuum cleaner. This is very convenient, as the design is designed to minimize the dispersion of small particles. You do not have to make any special efforts.
There are different models of such covers:
Some masters prefer to use homemade dust-collecting covers. They can be made from a plastic canister or a polypropylene sewer. They only need to adapt a vacuum cleaner. Similar instructions are quite a lot on the Internet.
As for cutting discs, the circles should be selected according to their purpose for specific materials. Pay attention to the fact that the tooling for dry cutting and suitable for wet, but not vice versa.
Is it possible to make out of the angle grinder chisel grinder
For laying communications such as electrical wires, water and heating pipes, in the walls, resort to the use of a specialized tool. strobore cutter. Such a tool has a significant disadvantage. it is quite high cost, and narrow focus. But do not get upset, because in the sale are special attachments chisel saws on angular grinder.
What is the need for this process
The design of a standard stitch cutter has a lot in common with an angle grinder or angle grinder. An essential difference from the angle grinder is the high rate of work, as well as the ability to easily regulate the depth of the cut groove. It can create a groove of such depth, which is required depending on the technological tasks set.
angle grinder is an excellent analogue of the chisel gun, as it can be used for repair work in residential and non-residential premises, where it is necessary to make special grooves or channels for laying pipes and electrical wires. In order to use the angle grinder as a stroborezera, you will need a special hood. It will allow not only to regulate the depth of the cutting tool, but also to work without dust.
In most cases, when it is necessary to make a groove in the wall, masters resort to the use of such tools:
It is important to know! Only if the work of the master is directly related to the need to make channels in the walls every day, then it is better to buy a professional chisel.
If you need to cut a channel in the wall during repair work, then for these purposes is quite suitable angle grinder. And there is no need to purchase a special attachment schtroborez for angle grinder, as it can be made by yourself.
How to make a grommet with an ordinary angle grinder
Mitre with an angle grinder can be performed in walls made of brick, concrete, cinder block and other materials. In order to make a grommet with an angle grinder you will need:
- Make a marking. A tape measure, rule or level, and a pencil are needed for this. Scribed lines should be bold, as when working with an angle grinder emits dust, because of which the marking may be imperceptible.
- Cutting out a mortise. By the ruled lines should pass the angle grinder with a diamond cutting disc, but keep in mind that the tool should be held with two hands, and work should be carried out in protective gear: goggles, mask, gloves.
- Knocking out or removing plaster. At the final stage, you will need to use a hammer and chisel to remove the plaster between the cut lines.
Grinder Hack Amazing Tool Idea
Important to know! Sometimes specialists use instead of one fixed disc on the angle grinder. two, which allows you to get a finished groove in one pass. This significantly saves time, as well as physical strength.
The main disadvantage of this method of strobing is the release of large amounts of dust. If the work is carried out in non-residential premises, then it is still not so terrible. If the room is residential, the dust not only hinders the process of drilling, but it also settles on the surface of furniture and appliances, that is pollutes the environment.
How to make a chisel from an angle grinder with their own hands
Before we will consider the way of making a grommet cutter from an angle grinder with your own hands, it is important to note that the tool is not at all designed to function with a double load. Such a variant, although effective, but the master performing the work, must understand what it is fraught with, both for the tool itself, and for its safety.
In order to turn an angle grinder into a floor saw with two cutting discs, the first disc should be screwed in with the standard nut, and the second disc should be secured with the nut from the skinning disc. If there are not enough threads for the second nut, you should put it in reverse. Stitching of this small size is suitable for laying electrical wiring. If, however, a larger groove is to be obtained, then shims must be used or an extension sleeve must be made.
Using an angle grinder as a grinder without a protective cover is not rational, as the master fly splinters of stones and dust. To avoid such negative consequences, you should make such a dustproof cover for your angle grinder. Such a nozzle will not only avoid getting on the master splinters, but also prevent the formation of dust, provided the construction of a special dust collector(or connection to a vacuum cleaner).
Important to know! To divert the dust should use a construction vacuum cleaner, otherwise ordinary vacuum cleaner will quickly become clogged, which will significantly reduce the effectiveness of its functioning.
To save from dust, you need to make a special hood. Making a protective cover on the angle grinder for stroeborezera allows the use of any improvised means: old plastic canisters, aluminum pots, plywood, pieces of laminate, boards, sheet of stainless steel, and so on. In general, you need something with which you can make a sturdy cover under the angle grinder. For dust extraction in such a cover should be provided with a hole for connecting a hose from a vacuum cleaner. The opening must be in the direction of the blade cut.
The disadvantage of such a cover is the inability to regulate the depth of cut. But this does not mean that you can not make such a cover, which could adjust the depth of cut. Below is one of the options covers schtroborez for angle grinder.
It all depends on the available arsenal of materials, as well as the imagination of the master.
Rules and restrictions when drilling
Perform perforation of the walls should be only after the room is ruled out a plan for location of hidden electrical wiring, or plumbing pipes. Performing work on shrovelling, it is important to consider the following factors:
Using peorator and angle grinder in the repair
First it is necessary to determine in what place of the room will be outlets. After that it is necessary to outline the way in which it is necessary to lay electrical wire. Drawing a marking on the walls, you need to take the peorator, drilled holes strictly on the line. The spacing between them needs to be 1 to 2 cm.
When the holes are ready, they should be connected. To do this, the peorator must be switched to a special mode called “hammer”. The partitions between 2 holes are best removed by holding the tool at an angle of 90°.
In the work, you can use a drill or a special wedge-shaped tool that works on the percussive principle.
If you choose to use a piercing tool, you should remember about a number of disadvantages of this method. Among these, the following are worth mentioning:
- Strong noise that occurs when the tool works. If repairs will take place in residential areas, it is necessary to inform the neighbors about the upcoming work in advance.
- You have to spend a lot of time on drilling out the walls. The process is time-consuming, it will require a specialist with experience.
- As a result of manipulation, you get strokes, the edges of which are of low quality.
- Debris and splinters will form in the room.
To replace the traditional method you can choose grinding by the angle grinder, equipped with a diamond disc. This method will make good quality edges. First you need to make 1 groove along the marking. Then, 3 cm away from it, make the second groove. After that, you need to take the peorator, switch it to the “hammer” and remove the material that is between the previously outlined furrows.
As a result, you get grooves with sufficiently good quality edges, but with an uneven surface. It can damage the insulation of the electrical wire. In addition, this method has several other disadvantages, and the main one is a large amount of construction dust.
Is there a technology for cutting concrete without noise and dust?
Thinking about what to cut the concrete with, you must also take care of reducing the amount of dust, which inevitably appears during the process of work. In some cases, you can not do anything and have to work in difficult conditions, but in other remove the dust is quite realistic. The main thing is not to violate the safety requirements and to use proven methods.
Concrete cutting is a purposeful mechanical impact on the monolith with rotating parts of the tool. Cutting is not accompanied by impact noise, but it always involves noise from the electric motor of the tool drive and the work of its moving parts that cut a groove in the stone or cut the armature, cut into pieces, etc.д.
Different methods are used for cutting concrete. manual, machine, wet and dry. The first two are conditioned by the type of tool chosen, the wet method involves the impact of water on the cutting part and on the concrete surface itself, the dry method does not use the water supply. Regardless of the cutting method chosen, the amount of dust that accompanies the process is always quite high.
- Diamond cutting of walls and partitions with hand tools (angle grinder and others).
- Diamond cutting with a stationary wall-cutting machine.
- Diamond cutting with floor saws.
- Use for wire cutting.
When using a hand-held tool (most often an angle grinder), a construction vacuum cleaner can be connected to it, which will suck up almost all the dust from the cutting process. If it is not possible to connect the tool to a vacuum cleaner, everything can be done with your own hands.
- Set the angle grinder as steadily as possible on the table or the floor so that it lies with the disc parallel to the plane of the base.
- Take the branch with pliers or a clamp, turn on the angle grinder and “saw” the pipe along the body, 3 centimeters under the cover of the tool.
- Tape the outlet to the body of the angle grinder with reinforced tape very tightly to the saw blade (a few centimeters into the saw blade). The nozzle has to be fixed firmly, so that it is fixed in a fixed position.
- Cover the open side of the guard with masking tape so that it is connected to the deflector. Then you can connect a construction vacuum cleaner and remove the dust during work.
During sawing, the disc must be driven to the surface of the concrete from the motor (preferably close to the spigot), so that the dust can be removed through a vacuum cleaner. It’s better to saw objects with the motor forward.
This system design changes in the tool does not imply, but before its use, it is desirable to consult with a representative of the manufacturer for the possibility of making revisions.
Cutting of concrete with hand tools
Not all hand tools are suitable for working with this material due to its strength. Most often for these purposes use an angle grinder (aka UGS, angle grinder). To cut the concrete use a special attachment in the form of a diamond wheel, which can be solid, segmented, combined.
Nozzles are selected according to the material to be sawn, as well as taking into account the type of work and conditions. Reinforced concrete with holes larger than 10 centimeters can only be cut with high-strength (turbine) discs. All disc segments are fastened to the blade by laser welding or silver soldering. The former can only be used for dry cutting, the latter for wet cutting.
The disc must have an inner diameter that matches the diameter of the angle grinder. The speed of the disc is also important. preferably higher than that of the angle grinder. Depending on the type of cutting and proper selection of the tool, the amount of dust created can vary.
So, if you spend a lot of time sawing concrete with an insufficiently strong and ineffective tool and nozzle, the dust will be very high and the result minimal. You can reduce the amount of dust with the wet cutting method. the water keeps the tool from overheating and prevents dust from building up. This speeds up the tool and increases the life of the diamond tool.
The water supply can be arranged in a variety of ways. from spraying the concrete with a sprayer periodically during work to attaching a hose to the tool so that the liquid flows in a continuous stream onto the disc.
If there is no water supply in the work area, you can think of some container for water or engage an employee, who will water the place of the cut and disk. It must be done in such a way that water does not get on the tool itself.
- No or minimal water consumption.
- Power consumption is small.
- If you choose the wet cutting method and angle grinder works from the network, the object must have access to 220 V and water.
- This method is relevant for cutting easily reinforced bearing walls, partitions with a thickness of 7-40 cm.
A convenient nozzle is made of an ordinary plastic can. You’ll also need a torch, a container of the right size, with a nozzle that matches the diameter of a vacuum cleaner hose.
Next, on both sides of the need to make planting holes for easy change of direction of rotation of the disc. A suitable size slot is made under the wheel, and another hole is cut to mount the torch. Carefully connect the hose to the neck of the canister, then fasten the adapter ring with a clamp. Angle grinder sent into the casing, all elements are securely connected. The hole, which is not used, is closed with a lid.
To make the cut even, you must first apply a marking, then along the line fasten wooden bars. After that, you need to make a shallow cut of up to 1 centimeter, remove the limiters, and continue working. All manipulations must be performed only with a respirator, goggles, gloves, overalls.
How to work with self-made grinder
When there is a need for a floor saw, the native cover is removed from the angle grinder. In its place is installed homemade nozzle, clamped with a clamp. The next step is to install the discs. If required, an extension spindle is screwed on. Without turning the angle grinder in the socket, hands rotate the diamond wheels. They should rotate freely and not catch the walls of the housing. Use the adjusting screw to set the depth of cut of the joint, try to turn on the angle grinder.
Vertical grooves are cut on the walls in the direction from top to bottom
Stitching with a homemade strobocutting cutter is no different from the procedure performed by a factory-made power tool. First draw a marking, connect the hose of a vacuum cleaner to the spigot, try to make a cut.
