How To Chisel An Angle Grinder Without Dust

The process of laying electrical wiring and fixing it has a number of nuances. After the completion of the work, the groove is closed. This can be done, as mentioned above, using plaster. Putties and plaster are used as alternatives.

Tool selection

Before starting work, you should definitely ask the question of how to gouge the walls for wiring. Today, a huge number of ways to carry out these manipulations are known. You can use:

  • Perforator;
  • Wall chaser;
  • Chisel and hammer;
  • Angle Grinder;
  • Impact drill.

A wall chaser is almost ideal as it allows you to get even cuts. However, its cost is high. But if you plan to use a puncher, then the manipulations can be carried out very quickly, and the work will have a low cost. With an angle grinder, these grooves are flat, but debris will form that is difficult to get rid of. The main advantage of the chisel and hammer is the low cost. However, if you want to achieve high quality, then you should not save on tools.

For reference

Now you know how to chase walls for wiring without dust. for this you should use a chasing cutter. It acts as the ideal modification for the angle grinder option. The device provides the ability to install a pair of diamond cutting wheels. You can adjust the distance between them. The main advantage is that the circles are covered with a casing that blocks the point of contact with the wall.

Using a puncher

You may be faced with the question of how to groove the walls under the wiring with a puncher. This method is one of the most common. This is due to the fact that the procedure does not require a lot of money and time. The first step is to prepare the walls. These jobs are no different from those when using other tools.

The master will have to check the presence of old electrical wiring. When wires are in the walls, unpleasant moments happen. You should not risk your health and life. A special device must be used for testing. At the next stage, the master will have to mark the walls. However, it is necessary to start marking only after you have made sure that there are no live wires in the walls.

From the central box, it is necessary to lead the mowing line to power sources, among them:

  • Sockets;
  • Switches;
  • Lighting Wires.

Care must be taken to provide protection against dust and dirt. Doors and windows are usually curtained because using a hammer drill will generate dust that will spread throughout the room. If you are faced with the question of how to properly cut the wall for wiring with a puncher, then you should read the information below. After completing the preparation, you can proceed to the main actions.

To do this, using a tool along the drawn lines, it is necessary to drill holes, which must be 1.5 cm apart from each other. Further, everything depends on the tool. It can be switched to slitting mode by using a special attachment. You can also insert a simple drill. The holes made in advance are connected with each other using a puncher. Beginners should not neglect the preparation, because without experience it is quite difficult to carry out such work, and it will be completely unrealistic to achieve an ideal result.

Why you shouldn’t choose a hammer drill

Before starting work, you can ask a question about how deep the wall should be channeled for wiring. Using a hammer drill, it is necessary to deepen by 25 mm. With the help of a spatula, in the next step, you can deal with the device of the groove. The main prerequisite for this is not to set the blade across the line. In this case, you will chip off the excess piece of plaster or wall. As a result, the strobe will not acquire the desired width and depth parameters, in addition, the appearance will not be very attractive. Slitting with a punch allows you to achieve the result, but the process itself is not very clean and fast.

Dust-free chipping tips

If you are faced with the question of how to chisel a concrete wall for wiring, then you should also think about how to avoid the formation of excessive amounts of dust. After the completion of work, its layer can be so impressive that only an industrial vacuum cleaner will be able to clean the room.

If you are interested in cleanliness after completing the manipulations, then you should prefer the wall chaser. It resembles an angle grinder, but has built-in diamond wheels. The presence of the casing allows you to adjust the pitch between the discs and control the depth of the furrows. The advantage of the wall chaser is the presence of the outlet for the vacuum cleaner. Dust during operation does not leave the casing. However, this method is not suitable for one-time work, because the tool can be purchased at a high price. But if you still want to get a clean room, then you can rent the unit.

Using a hammer and chisel

When wondering how to chisel walls for wiring, you can consider one of the simplest options. using a hammer and chisel. The length of the section to be punched out should be divided into separate segments. With the help of a chisel, the master will have to outline the grooves, the marks should be located along the edges of the future groove. The indentations should be equal to the width of the tool tip. After, having installed it across the direction of the future cable, part of the wall must be knocked out.

You should continue to remove the top layer further. You need to move along the intended mowing line, and at the end you can deepen the strobe by 25 mm along its entire length. After each removal of the top layer, you can deepen the strobe immediately. However, these tools cannot be used if the wall is concrete, since the material in its base is strong enough, so it will be difficult to work.

How and with what to cut walls for wiring without dust?

When carrying out repairs in their house or apartment, the owners usually face a stage when it becomes necessary to lay new electrical wiring. This is necessary to install new outlets, because in the intended places of their placement there is simply not always power supply.

You might think that to complete the task, you just need to purchase a branched wire, and also use the help of specialists. However, the services of masters today are not free, moreover, they can turn out to be very expensive, while you can easily cut the walls yourself. To do this, it will only be necessary to study the technology and correctly apply it in practice.

Using an angle grinder

If you still have not decided how to gouge the walls for wiring, then you can consider a technology that involves the use of an angle grinder. To do this, you should use a diamond disc, because the wall material is strong enough. Two strips should be cut in the marked area. The slots must be parallel. The step between them will be 2 cm.

Next, a punch or other tool is used to remove unnecessary residue between the cuts. You can use a hammer drill. After the wiring is placed in the opening and covered with plaster. The material should be removed to such a depth that it is convenient to lay plaster at the final stage. When the wires are completely hidden and located deep, there will be a free space that can easily be filled with composition.

Certain features also exist when chipping walls made of silicate bricks. Silicate brick is inferior in strength to concrete, and therefore it is easier to make grooves in it.

The peculiarities of chipping walls made of silicate bricks should include the fact that when chipping one should take into account its natural properties, such as increased moisture absorption and susceptibility to aggressive media.

Moisture, in the event of contact with a brick, worsens its thermal insulation properties, and the aggressive media present in the soil can lead to a reaction with the lime base of the brick and its destruction, as a result of which the entire building can be destroyed.

In this regard, when chipping walls made of silicate bricks, special attention should be paid to ensure that the strobes do not come into contact with source of moisture and open soil.

How to cut a concrete wall without dust. Technology for cutting concrete without noise and dust: is it possible or not? Little tricks. Drilling dust-free concrete

Drilling concrete or brick is not a tricky business. All you need to do this is a good hammer drill and a winded drill bit. Of course, you need to mentally tune in to noise and dust. If you can put up with a roar, then dirty furniture, household appliances and carpets will please few people. There are two methods in the fight against dust: folk and progressive. Let’s first look at the popular method, which, frankly, only works when drilling holes in the ceiling. How to drill dust-free concrete? An ordinary paper funnel attached to a drill helps to fight it.

DIY wall slitting methods

The methods of wall chasing depend on the tools used when making the chase. Let’s take a closer look at how you can grind a wall.

How to get rid of dust?

Various methods are used to combat dust during chipping:

    The most common and affordable way to deal with dust is to wet the surface on which the strobe is to be made.

In this article, we looked at the basic methods and tools for chipping walls. As you can see, this process is not very complicated, the main thing is to follow the safety rules.

A feature of slitting in concrete will be that concrete has high strength.

The question often arises: is it possible to carry out chipping of load-bearing walls in a panel house? You can, but there are some peculiarities here.

When making grooves in a bearing wall, special attention should be paid to the fittings that are located in the wall. Damage to it must be avoided, as this can lead to metal corrosion and possible weakening of the supporting structures. In order to prevent damage to the fittings, you need to use a metal detector.

In addition, when chipping the load-bearing walls of panel houses, it is strictly forbidden to do horizontal slitting, since the load-bearing panel is constantly in a stressed state and any reduced section of it can lead to the collapse of the floor panel and even the whole house.

If, nevertheless, the need for grooving cannot be avoided, then grooves on load-bearing walls should be placed only in the vertical direction, which corresponds to the direction of the stiffeners

When chipping the load-bearing walls of panel houses, as few recess folds as possible should be made, and the channel length should not exceed 3 meters.

Cutting concrete with hand tools

Due to the strength of the material, not every hand tool is suitable for working with it. Most often, an angle grinder is used for these purposes (aka UShS, an angle grinder). For cutting concrete, a special nozzle is used in the form of a diamond wheel, which can be solid, segmental, combined.

Types of angle grinder diamond wheels that can be used to cut concrete:

  • Solid. made with a continuous diamond cutting edge, so no chips appear in the work. The nozzle heats up periodically, therefore it requires constant cooling with a stream of water.
  • Segmented disc. solid base, segmented edge. The wheel is inexpensive, but wears out quickly from durable materials. Used exclusively for dry cutting.
  • Combined (aka turbo-diamond) disc. considered universal, capable of withstanding maximum loads, it can even cut reinforced concrete.

The attachments are selected in accordance with the material to be cut, as well as taking into account the type of work and conditions. Reinforced concrete with depressions more than 10 centimeters is cut only with high-strength discs (turbocharged). All segments of the disc are attached to the blade by laser welding or silver soldering. The first one can only be used for dry cutting, the second one. wet.

The wheel should be made with an inner diameter corresponding to the diameter of the angle grinder. The rotational speed of the disc is also important. it is desirable that it be higher than the angle grinder. Depending on the selected type of cutting and the correct selection of the tool, the amount of dust that appears during work may vary.

So, if you cut concrete for a long time with an insufficiently strong and ineffective tool with nozzles, there will be a lot of dust, and the result is minimal. Dust can be reduced by using the wet cutting method. water prevents the tool from overheating and prevents dust from forming. So it is possible to speed up the work and increase the resource of the diamond tip.

Water supply can be organized in different ways. from spraying concrete with a spray gun periodically during work to fixing the hose to the tool so that the liquid flows into the disc in a continuous stream.

A convenient attachment is made from an ordinary plastic canister. You will also need a cutter, a container of the required size, the neck of which, in its diameter, will dock with the vacuum cleaner hose.

Further, on both sides, you need to make mounting holes so that you can easily change the direction of rotation of the disk. A slot of a suitable size is made for the circle, and another hole is cut for mounting the cutter. Carefully connect the hose to the neck of the canister, then attach it with a transition ring with a clamp. the angle grinder is sent to the casing, all elements are securely connected. The hole that is not used is closed with a lid.

To make the cut even, you first need to apply markings, then wooden blocks are attached along the mowing line. After that, you need to make a shallow cut up to 1 centimeter, remove the limiters, and continue working. All manipulations must be performed exclusively in a respirator, goggles, gloves, overalls.

Dust-free concrete cutting: how to saw an angle grinder with your own hands, a tool

Cutting concrete without dust is practically impossible, since in the process of sawing and processing stone, one way or another a lot of dust appears, the volume of which can only be reduced. But it is also advisable to do this, since too much dust in the process of performing work brings a lot of troubles: it spoils the tool and blunts parts, settles in the lungs and on all surfaces in the room.

With the use of modern equipment, it has become easier to saw concrete. there are special cutting tools, consumables for them. Devices can be hand-held or stationary, powered by electricity or other sources. As a rule, all concrete cutting tools are equipped with diamond parts. chains, discs, crowns, brazing, etc.

Concrete cutting with wall saws

Wall saws are used to cut concrete on larger scale and complex jobs. Less dust than an angle grinder, much higher productivity and efficiency.

Features of cutting a concrete monolith with a wall saw:

  • Diamond cutting of this type is characterized by a large cutting depth, therefore, it is used for industrial cutting of hatches / openings, other elements with heavy reinforcement in partitions, walls, floor slabs. Works are carried out in the shortest possible time.
  • To accomplish the task, you need to provide free one-way access from 30-35 centimeters.
  • It takes a lot of water for cooling (up to 15 liters per minute), so it should be possible to restock.
  • Waste water can be collected with a standard vacuum cleaner.
  • To operate the equipment, an alternating current network with a capacity of 32A and a voltage of 380V is required.

Cutting concrete with ropes

This method is used less often than all of the above, but is also relevant when performing certain work.

How concrete is cut using special ropes:

  • To accomplish the task, a special rope and diamond bits are used, as well as a drive. You can cut any structure without limitation in thickness (including columns, for example).
  • For optimal operation of the equipment, it is imperative to ensure the supply of cold water under high pressure and a network with a voltage of 380V.
  • The cost of work can be different and depends on such factors: the type of material, the type and size of the opening, the thickness of the structure.
  • Dust when using this method appears a minimum amount, noise is also created a little.
  • Wire cutting allows you to quickly cut openings of any configuration with perfectly straight edges, even where access is limited.

Is there a technology for cutting concrete without noise and dust

Thinking about what to cut concrete, you need to take care of reducing the amount of dust that inevitably appears in the process of performing work. In certain cases, nothing can be done and you have to work in difficult conditions, but in others it is quite possible to remove dust. The main thing is not to violate safety requirements and use proven methods.

Different methods are used to cut concrete. manual, machine, wet and dry. The first two are due to the type of tool chosen, wet assumes the effect of water on the cutting part and on the concrete surface itself, the dry method does not use water supply. Regardless of the chosen cutting method, the amount of dust accompanying the process is always large enough.

The most common methods for cutting concrete are:

  • Diamond cutting of partitions and walls with hand tools (angle grinder and others).
  • Diamond cutting using a stationary wall saw.
  • Diamond cutting with floor saws.
  • Use for cutting rope.

When using a hand tool (most often an angle grinder), you can connect a construction vacuum cleaner to it, which will suck in almost all the dust that appears during the cutting process. If there is no possibility of connecting the tool to the vacuum cleaner, everything can be done by hand.

What you need to create an adapter for a construction vacuum cleaner:

  • Sewer outlet made of polypropylene with a diameter of 50 mm, at 45 degrees.
  • Reinforced tape (it is more reliable).
  • High quality masking tape.

The process of creating a dust extraction attachment:

  • Place the angle grinder as firmly as possible on the table or floor so that it lies upside down with the disc parallel to the base plane.
  • Take the branch with pliers or a clamp, turn on the angle grinder and “saw” the branch pipe along the body, 3 centimeters under the tool casing.
  • Reinforced with tape very tightly, in tightness, tie the bend to the body of the angle grinder, slightly going into the saw blade (a few centimeters). The fixing of the branch pipe must be secure so that it is fixed firmly.
  • Mask the open side of the casing with masking tape, thus connecting it to the outlet. Then you can connect a construction vacuum cleaner and remove dust during operation.

Such a system of design changes in the tool does not imply, but before using it, it is advisable to consult with a representative of the manufacturer for the possibility of making improvements.

Concrete cutting with floor saws

Seam cutters are also often used for tasks of this kind. There are some features that are desirable to explore.

Key features of cutting concrete with a floor saw:

  • Usually one of two types of productive equipment is used. gasoline / electric. The latter option requires a network connection, gasoline units can be used anywhere (in the field, in open areas, to create expansion joints in the road surface, etc.).
  • It is necessary to provide a supply of cooling water under high pressure, which will eliminate the risk of overheating and reduce the volume of dust.
  • For gasoline devices, it is important to provide the possibility of ventilation of the supply and exhaust type, if work is carried out in a closed room.
  • Electrical equipment will need a 380V AC connection.

It is important to know

Modern manufacturers offer a variety of equipment models, so it will not be difficult to find a specific model of equipment in the regions (as well as companies or specialists who will quickly and efficiently perform work). But you need to remember some of the nuances.

Things to keep in mind when cutting concrete:

  • Wall saws are not used in multi-storey panel-type buildings because of the risk of flooding the lower floors with water. Also, the machine is not suitable for work in a confined space, if necessary, perform small volumes of cut.
  • To reduce noise, you can cut openings in parts (at least 6 parts). The price of work in this case rises and depends on the number of cut pieces.
  • All openings / openings in supporting structures are made only by certified companies and in strict accordance with the rules.
  • Legalization of hatches / openings in load-bearing walls requires an appeal to state authorities with the provision of a full package of documents.

Dust-free concrete cutting is a complex task that can only be partially achieved. It is very difficult to get rid of dust completely, but its amount can be significantly reduced thanks to the correct choice of equipment and nozzles, the cutting method, as well as the use of a construction vacuum cleaner and the creation of special devices for collecting dust.

Concrete wet cutting technology

The use of water allows you to cut concrete “angle grinder” without dust and overheating of the tool. The technology allows to solve several problems at once:

  • Extend the resource of the diamond tip,
  • Avoid dust formation,
  • Increase work speed.

One way to keep the water flowing continuously is to secure the hose so that the liquid flows onto the disc. If there is no plumbing in the work area, an assistant can be involved in the process. He will use a primitive plastic bottle fixture to wet the circle. At the same time, the incision site is moistened with a liquid. This must be done carefully so that water is not poured into the instrument.

The method is not very applicable in multi-storey buildings, since there is a risk of flooding the neighbors from below.

How to choose a disc for an “angle grinder

Concrete is a durable material, so it is quite difficult to work with it. To perform cutting, an angle grinder (angle grinder) is most often used. This tool is better known in everyday life as an “angle grinder”.

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

  • Segmental,
  • Solid;
  • Combined (turbocharged).

The first option is a solid base with a segmented edge. Such a circle is notable for its low cost, but is not very suitable for working with durable materials. It should also be taken into account that it is used only for dry cutting. The solid disc has a continuous diamond edge to prevent chipping during operation. Such a nozzle heats up quickly, therefore it must be cooled with a continuous water jet.

Before buying a nozzle of the right type, you need to figure out what material you will have to work with. Reinforced concrete is reinforced with metal rods, which in the process the cutter can stumble upon. Therefore, if a deepening of more than 10 cm is expected, use discs of increased strength, that is, turbocharged. Fresh concrete is more abrasive, over time the material hardens, its strength increases. This factor should also be taken into account when choosing a cutting wheel.

Segments of the disc are attached to the blade with silver solder or laser welding. The first option is more suitable for wet cutting, the second is used only for dry cutting. When choosing a suitable diamond wheel, you should pay attention to its diameter, which should be suitable for the parameters of the angle grinder. The rotational speed of the disk is also an important criterion. It is better if it is higher than the maximum possible indicator stated in the technical characteristics of the “angle grinder”. This will ensure optimum performance.

Tips for cutting dust-free concrete

During repairs or construction, sometimes it is required to carry out work on concrete: cut out an opening for a window, a niche, cut walls for wiring. Masters know how many small particles are formed in this case. Cleaning after such events is a very laborious task. We offer you to figure out whether it is possible to cut concrete without dust and how to organize this process.

How to make a casing for a vacuum cleaner with your own hands

An angle grinder with a built-in vacuum cleaner allows you to get rid of the small particles of material formed in the process of cutting the “angle grinder”. But what if there is a need to cut concrete with an ordinary tool without additional options? The simplest solution would be to purchase a casing for a vacuum cleaner separately, or to make a device yourself. You can attract an assistant who will collect the particles formed during the sawing with a vacuum cleaner.

It is easy to make a convenient attachment from a simple plastic canister, which is often used to sell a car “anti-freeze”. For work, you will need a construction cutter and a container of a suitable size, the neck of which will fit in diameter to the vacuum cleaner hose.

The manufacturing sequence is as follows:

  • Fitting holes are cut on both sides so that you can easily change the direction of rotation of the disc.
  • A slot of a suitable size is made under the circle.
  • Another hole is cut to attach the “angle grinder” cutter.
  • The hose is docked with the canister neck and secured with an adapter ring with a clamp.
  • Angle grinder” is placed in the casing and all elements are connected.
  • Cover the unused opening with a lid.

A good dust collector can also be obtained from a simple five-liter plastic bottle. It is attached using a standard protective cover, and the vacuum cleaner nozzle to the neck. This design is suitable for any kind of work, except for chasing.

One final tip: in order to make the cut straight, the markings are first applied. Then wooden blocks are fixed along the mowing line. After that, a shallow incision up to 1 cm is made, the stops are removed and the work continues. Throughout the entire process, coolant is supplied to the disc blade. All manipulations must be carried out with goggles, a respirator and gloves.

Than the walls are chased

The standard arrangement of lamps or sockets does not always suit the owner of the apartment. In this case, the question arises about their transfer to another place. To do this, it is necessary to make grooves or holes in the walls or ceiling. In multi-storey buildings, they are made of concrete or brick. Therefore, if it is necessary to groove walls for wiring, it is better to take care in advance in order to avoid a large amount of dust.

You can make the grooves in the wall manually, but if you need to lay a long cable, it will take a lot of time. Therefore, it is better to use a power tool. For work of this kind use:

  • Puncher,
  • Angle Grinder,
  • Wall chaser,
  • Impact drill,
  • Stages and hammer.

The use of a hammer drill has a number of disadvantages. First, the instrument makes a lot of noise. Therefore, if work is being carried out in a residential building of a high-rise building, you will have to negotiate with neighbors. The process of chipping with a hammer drill is quite laborious and time-consuming. In addition, the resulting indentations have an uneven edge. A traditional “angle grinder” with a diamond disc produces holes with a good edge, but the grooves themselves have an uneven surface. This creates the risk of damage to the wiring, and too much dust is generated in the process.

The ideal option would be a wall chaser. With its help, you can quickly and easily make holes and grooves for an electric cable. This tool cuts with two blades. They are insulated with a casing that covers the point of contact with the surface. This makes it possible to punch furrows of different depths. The strobes are smooth on the inside, and their edges remain even.

In the absence of a power tool, you can also make a strobe manually. For this purpose, a chisel and a hammer are used. This technique is not suitable for hard materials such as sand-lime brick or concrete. With the help of a chisel, a groove is punched in the wall, which is then deepened and widened. At the same time, the tool is held in the right hand, parallel to the surface, and hit with a hammer.

Tips on how to grind walls for dust-free wiring

Any master knows that when replacing wiring in an apartment, you have to make holes in the walls. The resulting construction dust is deposited throughout the room. Is it possible to facilitate the process of work and subsequent cleaning?

A few tips on how to carry out dust-free chasing will be useful to those who are starting a repair.

How to get rid of dust when chipping

Professional builders use equipment with a built-in vacuum cleaner when laying wiring inside walls. But the cost of such a tool is high and it makes no sense to buy it for a one-time event. In order to grind the wall with a wall chaser without additional options, without creating a cloud of dust, craftsmen have to go to different tricks. The simplest way is abundant wetting of the treated surface with water. Small particles can be collected with a simple household vacuum cleaner.

To grind an angle grinder without dust, use the technology of wet cutting of concrete. It consists in the continuous supply of water to the cutting disc through the attached hose. You can use the help of an assistant who will simply water the disc and the cutting area from a plastic container. When doing this, be careful not to let liquid get on the power tool.

The following measures will help to reduce the dustiness of the room:

  • The floor is covered with plastic,
  • An industrial curtain or fabric is fixed above the entrance,
  • A wet rug is placed in front of the door.

After the strobes are done, the debris is swept away with a broom and vacuumed. The deepening is treated with soil, laid and fixed the cable. The channel is sealed with putty, plaster or plaster.

You can run electrical wires without chipping the walls. This option is attractive due to the complete absence of dust. The trade network contains many different products that allow not only to disguise open wiring, but also to revive the design of the room. These include:

  • Corrugated sleeve,
  • Cable channels,
  • Boxes.

If there is a need to replace the wiring, without laying a new one, you can use the existing channels.

Small particles of concrete and sand-lime bricks should not enter the mucous membranes or the respiratory tract. Therefore, when carrying out work, it is necessary to use protection in the form of glasses and a respirator. If there is furniture in the room, it is also better to cover it with a film or cloth.
