How to drill concrete with a conventional drill

How to properly drill concrete with a drill?

Typically, such work is performed in the following cases:

  • rough finishing of premises;
  • installation of built-in furniture and appliances;
  • installation of wiring and plumbing when communications are required to be concreted.

When using a victorious nozzle in the course of work, it is required from time to time to use a metal punch, which is selected to the size of the hole being formed. Such a tool allows the drill not to jam when the drill is deeply immersed: the punch is placed in concrete and deepened by hammer blows to make a hole in the wall, destroying the seal.

This process is quite long, an alternative can be the use of diamond core bits: a drill equipped with such nozzles will not get stuck in concrete.

Working with an impact drill with a diamond core bit

  • Before drilling a hole in the wall, you need to install the desired nozzle, after making sure that the tool is in good working order and the drill is intact..
  • It is required to drill the concrete carefully; when using low-power equipment, the duration of the continuous operation of the drill should not be more than 10-12 minutes. If the drilling is delayed, it is required to take breaks so that the motor of the device cools down..
  • After drilling the concrete wall, it became clear, then in addition it is worth considering that for each new hole it is required to process the nozzle. You can moisten the surface with water to facilitate the procedure and save the metal from deformation.

The whole process of work can be viewed at

If you encounter a jammed drill, do not pull it out by force: this will break off the tool, leaving the tip in the concrete. The nozzle needs to be disconnected, select a crown with a reduced diameter and use it to pull out the stuck element.

How to properly drill a concrete wall

The process of repairing an apartment includes many works related to the creation of holes in the walls: for this, a tool of various designs and power can be used. Many craftsmen and those who are going to carry out repairs on their own want to know how to drill a concrete wall with an ordinary drill, and if this is possible at all. For such work, a perforator is usually used, but it is not always suitable for this, besides, if the tool is to be bought, then its cost is much higher than that of a drill.

Which attachments to choose?

Before drilling a hole in a concrete wall, you need to select a nozzle of the appropriate design. The following varieties are used for work:

  • Impact-type tooth crowns for drilling. When working with concrete, it is recommended to use a variety of separate soldering teeth, made from the most durable metal alloys. Many bits are equipped with SDS shanks for installation in keyless drills. Drills are well suited for concrete walls, however, on contact with metal, they can begin to collapse, therefore, before drilling a reinforced concrete wall, you need to check that there is no reinforcement in the place of work..
  • Diamond core bits, which are designed for hammerless drilling of holes. Such nozzles are more modern, with their help it is easier to make a hole in a concrete wall. The edge of the crowns has an abrasive structure and special cutouts; during production, it is processed by spraying diamond chips or corundum. Before making a hole in the wall, you just need to select the desired length of the nozzle: in everyday life, varieties with a diameter of up to 100-120 mm are used, in professional work, larger crowns are used. A distinctive feature is the ability to drill without the risk of damaging the fixture with fittings.
  • KS-bits, which have a cutting edge with crystalline diamond particles. These attachments are used on most solid walls, including drilling into concrete slabs, exterior walls, and stone structures..

Before working with drilling equipment, you need to choose a nozzle that is suitable in composition, thickness and length.

Before drilling a load-bearing wall or partition, you need to make sure that during the work the wires or cables, if they are laid inside, will not be touched..

Features of the choice of tool

In most cases, it is better to use a perforator for drilling concrete: it has increased power, is designed for punching hard surfaces, and allows you to make holes large in diameter. The use of the tool is impractical in the following cases:

  • the need to drill the wall to a depth of 10-12 mm;
  • work with foam concrete, which crumbles when processed with a perforator;
  • in work it is required to make no more than 10-15 holes.

Concrete drill

Before drilling a wall, it is important to choose the drill itself: it should not be hammerless, since this type is ineffective when drilling concrete, the nozzle and cartridge become unusable almost immediately. The nozzles themselves must be victorious, intended for concrete work, the tip – with a carbide coating.

In some cases, a good solution would be to purchase a hammer drill: the device is more expensive than the classic model, but it has increased power that can be adjusted.

Expert advice

Before deciding how to drill concrete walls and getting started, you should pay attention to the following recommendations:

  • if the hole diameter exceeds 12 mm and the depth is 10-11 cm, it is better to use a hammer drill or a hybrid device (drill-hammer drill);
  • if holes are made for plastic dowels, the depth should be 7-10 mm greater than the size of the fastening element, since concrete dust and small particles of stone remain inside;
  • it is recommended to start work at low speeds so that the nozzle does not move due to the increased torque, and the impact mode is turned on when the drill passes 2-4 mm in depth;
  • the dust generated during the drilling process can be removed with a vacuum cleaner, it is advisable to do this in the process, periodically stopping the drill and cleaning the hole from concrete particles;
  • it is imperative to observe safety precautions during work: it is required to wear gloves to eliminate the risk of sliding of the handle and goggles so that the crumb does not get into the eyes and damage the mucous membrane.

Dowel Drill Size Chart

In most cases, a concrete wall is drilled with a perforator, dispensing with a drill. If, as part of the repair, you need to make no more than 15-20 holes or the wall is made of foam concrete, using a drill is the best choice that will save time and money.

Before punching a hole, you need to make sure that there is no wiring in this place, and check whether the nozzle is suitable for such work (the duration and efficiency of work depends on which drill the drill is equipped with). When deciding how to drill the wall, you should pay attention to the victorious crowns: with such a drill using a drill, you can easily punch a hole up to 10-12 cm deep.

Features of working with concrete pavement

First, select the drill. If the wall is made of concrete or brickwork, it is better to give preference to the victorious nozzles, since this tool turns the material into crumbs at the drilling site. But it is not suitable for other surfaces, for example, if you drill wooden boards with them, the fibers will tear, and the hole will turn out to be sloppy.

Hammer Drill vs Drill | Which is Faster in Concrete?

When drilling a concrete surface, it must be borne in mind that there will be a lot of dust, therefore it is necessary to prepare a vacuum cleaner to collect debris from the hole. This, of course, does not guarantee absolute cleanliness during work, but it allows you to reduce the amount of dirt..

Before you start drilling, it is necessary to check whether communications pass in that place. Damage to electrical wiring will entail the injection of additional funds into its restoration. You need to ring the wall beforehand for this you can use an alarm device or a metal detector.

Now you can go directly to drilling holes in the concrete wall. To begin with, we outline the place where the future hole will be with a construction pencil. We start drilling at a low speed, this will increase the accuracy of the work. After that we increase the speed. The serlo should enter the surface at one angle so that the drilling direction does not get confused and the hole is of the desired size.

If a hole is made for a dowel, it must be longer than the dowel itself so that it can be installed flush with the wall and it does not protrude.

Large diameter work

At the beginning of the work, they outline the area in which the hole should be formed. It is important to observe the dimension here. When the hole diameter is 100 mm, the circle needs to be drawn about 20 mm. This is typical for situations where the drill deviates from the working circle. Even a small shift can damage the surface if you do not take this into account from the very beginning. You need to make sure that the drill goes through the walls. Only in such a situation can you be sure that the hole will be made correctly..

How to drill wood surfaces

Wood is the easiest material to drill. But there are also some features of the technological process that must be observed so as not to spoil the surface and not to break the equipment. Speed ​​parameters depend on the type of wood flooring. Loose specimens can be drilled easily. The following types of equipment for wood can be distinguished:

  • flat or feather;
  • twisted, they are single-spiral;
  • crowns, also called core drills;
  • cylindrical nozzles of the Forstner type.

Choosing a drill. As a rule, for small holes (less than 1.2 cm), metal tooling is used, if a larger diameter is needed, you will have to fork out for a specialized wood drill.

For large holes, ring crowns must be used. For drilling blind areas, Forstner-type crowns are perfect..

Particular attention must be paid to drilling the timber. Despite the fact that it is very convenient to fix, its thickness often becomes a negative factor that complicates the work. If the timber is of a standard size, then, as a rule, drills up to 25 mm are taken. The drilling process always takes place at low speeds.

How to properly drill walls with a drill

If such a question arises, then most likely we are talking about how exactly you need to hold the tool in your hands so that the holes are not too large. If you need to make a hole at an angle, then you need to use special drill bits. To fix the tool on the surface, you can purchase a stop nozzle, this will allow you to drill more accurately and the drill will not go in another direction.

How to smoothly drill concrete with a drill

First you need to know for sure that you have selected the correct nozzle. It is always necessary to drill at low speeds. Usually, the tool is in operation for 10 or 12 minutes. During this time, it is guaranteed that it will not overheat and accidentally break. If the drill bit of the tool accidentally remains in the wall thickness, you must carefully remove it. Force cannot be used. Perhaps the drill will break and its fragments will remain in the thickness of the wall. If necessary, the drill can be easily detached from the nozzle.

The drill must be held strictly perpendicular to the surface. If this is not followed, there is a risk of damaging the drill and sometimes leaving a dent. It is also important to take care that drilling dust does not get into the eyes. For this, goggles are purchased. Gloves can also be used to prevent slipping of hands during the process. Only a person with strong enough hands can drill the surface qualitatively. Because the process requires a lot of effort.

How to drill a brick wall

Drill brick with a drill. uncomplicated process. An impact drill is used for work. If drilling is hammerless, then the drilling process can be delayed for a long time. It is very important that the tool runs at high power. The quantitative indicators of revolutions per minute are also important. Indicators of more than 2,000 revolutions are considered the most acceptable.

Of course, a puncher is used to perform better work. If it is not at hand, then high-power drills are used. You don’t need any to drill a hole. then special knowledge. The main thing is to follow a number of simple recommendations, which were mentioned above. Sometimes you can stumble upon a burnt stone. It will be quite difficult to form a cavity in it. Such a brick is determined by the dust generated during operation. It becomes a pronounced black hue.

To form holes in burnt rocks, you need to turn on the drill at low speed and put the impact function. The instrument must be pressed very hard for the impact function to work properly. It is also important during work to ensure that the drill does not overheat. A severely overheated drill will cause the edges of the drill to wear out quickly. For such purposes, a diamond-coated drill is most often used. In this way, the grip is most effective. This leads to significant savings in physical strength and energy..

Sometimes there are situations when the hole made needs to be made of a significant diameter. For example, this could be a ventilation outlet. It will be very difficult to organize such work with an ordinary tool. You will need powerful equipment and large crowns.

How to drill a tile with a drill

Ceramic surfaces have proven to be particularly fragile coatings. The outcome of drilling in such areas is determined by the quality of the tile itself. If the master performing the work did not make mistakes during the installation work, then the drilling process should go smoothly. A competent installation is understood to mean one in which no empty zones are formed between the wall and the covering. If there are voids between the tile and the wall, then the tile may burst or break off during drilling..

We start by choosing a drill. There are specialized attachments for ceramics and glass, but you can also use concrete attachments with victorious spraying. It is important that the drill bit for concrete is new enough, otherwise it will slide on the tiles and scratch the base, which will damage the masonry.

The process of drilling the tile should take place at low speeds in order to prevent chipping of the glaze coating of the decorative surface. After we have drilled the ceramics, we change the drill, if using a ceramic drill, we make a hole in the wall.

How to make a hole with a drill

First, you need to prepare a drill, attachments and other related items. Then, in the process of work, you will not have to be distracted and spend time looking for the right things..

Drilling is often necessary in cases where it is required:

  • rough finish;
  • laying of wiring;
  • plumbing installation;
  • concreting of communications.

In this case, the concrete wall (if drilled correctly) should remain without severe damage and large chips.

How to Drill Into Concrete | The Home Depot

When working with a drill with a victorious bit, sometimes you need to use a metal punch. It is selected in accordance with the size of the hole. This tool allows the drill to not jam when the drill is buried. To do this, the punch is driven into concrete and hammered into pieces in order to split a solid obstacle into pieces. This process can take quite a long time, so it is better to use a diamond core bit. In addition, a drill with such a nozzle will never get stuck in concrete..

Drilling sequence:

  • Examine the tools carefully. The drill must be in good condition and the drill must be intact.
  • Start carefully drilling a hole in the concrete with a drill, stopping the continuous operation of the tool after 10 minutes from the start of action.
  • The process can be continued only after the motor has cooled down..
  • Before drilling the next hole, it is necessary to moisten the nozzle with water. This will protect the metal from bending..

Using such simple methods, you can drill a concrete wall without a punch..

Sometimes there are times when the drill gets stuck in the wall. It is not advisable to use force in this case, otherwise it will break off, and the edge of the nozzle will remain in the concrete. To free the drill, you must first disconnect it from the drill, then put on a crown of a smaller diameter and get out the stuck part.

To perform drilling on your own and at the same time to avoid various injuries and unpleasant incidents, you need to follow safety precautions and follow the recommendations of specialists.

Power selection for drills

The optimal power for working on concrete, in order to drill a hole, is considered to be a power of at least 600 W and 2500 rpm, but this figure must be adjusted depending on the manufacturer’s recommendations so as not to spoil the drill. As already mentioned, concrete “crumbles” when we drill, and this does not require too much speed..

If you encounter a jammed drill, do not pull it out by force: this will break off the tool, leaving the tip in the concrete. The nozzle needs to be disconnected, select a crown with a reduced diameter and use it to pull out the stuck element.

Which nozzles are better

To be able to drill a concrete wall with a drill, you must first select the appropriate nozzles. They must match the design exactly.

The following types are suitable for work:

  • Impact type notched crowns. They perform the function of drilling. For working with concrete, it is best to purchase a variety of tines soldered separately. Since they are made of durable metal alloys.
  • Diamond core bits. This type is suitable for hammerless drilling. Such nozzles are more advanced, so getting a finished hole in concrete can be much faster and easier. These crowns have special shaped notches and an abrasive structure at the edge. It remains only to choose the required length of the nozzle. In private use, varieties with a diameter of up to 120 mm are usually used..
  • Bits of standard KS with a cutting edge covered with diamond particles. Attachments are used on stone, solid walls, concrete slabs and exterior walls of buildings.
  • Drills for concrete. Ideal for wall drilling without reinforcement. Otherwise, they may break..
  • Before using any attachments, it is necessary to check the wall for cables and wires, as well as fittings (if there is a metal detector). This will help protect the wall from major damage, and the tool from breakage..

    How to choose a tool

    Most often, a perforator is used for drilling concrete. It has several advantages over a conventional drill..

    These include:

  • increased power;
  • chiseling function with different types of chisels;
  • drilling large (in diameter) holes;
  • the ability to punch through particularly hard materials.
  • Despite the listed advantages, such a tool is not always suitable for work. In some situations, its use is simply impractical..

    The hammer drill will not work in the following cases:

    • when shallow holes (10–12 mm) are needed in the wall;
    • when working with a foam block (otherwise the material will crumble);
    • if the required number of holes does not exceed 15 pieces.

    Based on this, we can conclude that a conventional drill is more suitable for home use. To purchase such a tool for drilling walls, you need to consider a number of important points..

    The drill must meet the following requirements:

    • It should be percussive, since this type is most effective when drilling concrete walls. In a hammerless drill, bits and chuck will fail too quickly.
    • It is better to buy nozzles for it pobeditovye, intended for work on concrete. And the tip is coated with durable alloys.

    You can also choose a hammer drill. True, such a tool is more expensive than a conventional model. But on the other hand, it has increased power, which can be adjusted at your discretion..

    Drill selection

    This point can rightfully be considered the main one, since the quality of work and the safety of the drill itself, as well as the accuracy of work, depend on a properly selected drill. Today, there is a huge variety of different drills on the market: for working on wood, metal, concrete. The latter are distinguished by a triangular tip. For a concrete surface, it is best to use a carbide drill, for example, a victory drill. This type of drill crushes the material without tearing it, which is ideal for concrete floors..

    drill, concrete, conventional

    If in the process of drilling the wall, the drill does not go forward, encountering a dense area, it is recommended to use a punch. After inserting a punch into the hole, they beat it with a hammer until it starts to move forward and softens the problem area. Then you can continue drilling..

    It should be noted that without a punch, a perforator can easily cope with this kind of difficulty, however, it makes holes that exceed 13 mm in diameter. If you want to use universal drills when drilling, you need to remember that they require cooling, vibration off and are only suitable for a conventional drill.

    Choosing a tool and working with it

    When choosing a tool to drill a hole, you should understand that your work depends on it. A good drill accurately drills a concrete wall or other necessary material, simplifies the drilling process, while a bad one will take a lot of time, may not cope with the task, or complicate it. What you need to pay attention to when choosing a drill:

    • Is it possible to change the drilling speed? – this point is important, since the correction of the speed mode will ensure the accurate operation of the drill, helping it not to damage the surface.
    • Is it possible to hammer drill and adjust the depth? – hammer drilling can be applied to problem areas, softening them.
    • Is it possible to hold the drill with both hands? – the drill is not an easy tool and therefore models that are equipped with handles should be preferred.
    • Is the power of the tool sufficient for your job??

    Having decided on the drill, before starting work, you need to get the hang of it. To do this, take the drill in one hand, like a pistol, place the other hand on the tool handle (if it is not intended by the design, the hand is placed near the cartridge). It is necessary to hold the drill in your hands strictly horizontally so that the hole does not work out with distortions and at the wrong angle. Wait until it reaches the ambient temperature before turning on the drill. Sudden temperature changes can cause condensation. If during work you decide to rest – disconnect the tool from the mains.

    Surface preparation

    Before you start drilling, you need to make sure that there are no wiring, pipes, electrical cables in the selected overlap location. A metal detector will help to cope with this task, as it reacts to non-ferrous metals, iron and steel..

    If you ignore this condition, you can stumble upon fittings, damage the drill, or cables / pipes that were hidden in the ceiling. If this section satisfies all of the above requirements, then a point is marked on the wall, and then a small depression is made in it at a slow speed using a drill. It is also worth remembering that the surface of a concrete wall is looser than subsequent layers..

    World of concrete

    To hang a picture or a photograph in a frame, you should not drill a capital wall, but if the situation calls for this, then you cannot avoid getting to know a punch or drill. Performing this procedure using a modern power tool will not be difficult if you know how to do it correctly..

    How to drill a concrete wall with a conventional drill

    Many people live in houses with concrete walls, and when it becomes necessary to make a hole in them, they face serious difficulties..

    Do not despair and get upset if you did not immediately manage to hang a shelf, lamp or cabinet, read our recommendations and everything will work out.

    There are several options with which you can independently drill a concrete wall..

    Making a hole in the wall

    Before making a hole in the wall, make sure there are no electrical wires or other cables under the intended location. Drilling in such a place is fraught with damage to the electrical wiring, harm to your own health. In order not to get on the cable, you need to do a few simple steps:

    • Examine the wall carefully: are there any switches or sockets? The wires must extend from them in the vertical direction for connection in the junction box. These rules must be followed by good electricians, but no one is immune from a pseudo-specialist. In order to save wire, such electricians use diagonal wiring..

    The wires are most likely about ten millimeters deep. To check the wall for cables, use a screwdriver to poke a small hole to about this depth..

    • If you did not find the wires, you can start drilling. But be careful the first twenty millimeters – start with a small number of revolutions, occasionally check if a wire is in your way.

    Perforator

    When using a hammer drill or impact drill, they must be switched to impact mode, a working tool with a victorious tip is inserted and it must be directed perpendicular to the wall surface.

    If the holes are drilled for a long time, then periodically it is necessary to wet the drill so that it does not overheat too much.

    After you have drilled to the required depth, you need to pull the working tool back without turning off the hammer drill. To clean the finished hole from dust, it is necessary to deepen and pull out the drill several times.

    Expert advice

    In order for you to be able to properly drill a concrete wall, you must have the necessary equipment, carry out all work carefully and adhere to the following recommendations:

    • without a punch, work can be done with a hammer drill or drilled with a screwdriver;
    • do not buy cheap drills, as the victorious tip falls off very quickly and they fail;
    • instead of a punch, you can use a victorious tool, with one you will break crushed stone, and with the second, inserted into an ordinary electric drill, drill;
    • to work with concrete, the rotary hammer must have an SDS-plus cartridge;
    • take into account the placement of the reinforcement, to determine where it is located, you can use a metal detector, if the reinforcement is bare, it must be painted to prevent rusting;
    • for working with concrete, you can use universal diamond-coated drills, but you need to insert them only into a regular drill, or you need to turn off the impact mode.

    Features of the

    Concrete structures are highly durable, so it is quite difficult to drill them yourself..

    This is due to the fact that crushed stone is used to create concrete products and when you get on it while drilling, the process becomes very difficult..

    The need to drill a concrete wall occurs quite often, it is necessary for the installation of shelves, cabinets, an air conditioner, gluing wallpaper, fixing a lamp, when attaching insulation or during plastering walls for attaching beacons.

    There are several ways to solve this problem:

    • using a hammer drill or a powerful impact drill;
    • an ordinary electric drill or screwdriver;
    • diamond drilling.

    It should be remembered that for walls made of relatively soft materials, it is impossible to use victory drills, since the holes will turn out to be uneven, and the wall will collapse. It is also impossible to work with metal with such a tool..

    To create large holes or cut a doorway, diamond-coated core drills are used. To use such a tool, it is necessary to use special installations, they allow you to make holes with a diameter of up to 250 mm.

    Since the cost of such equipment is high, it is easier to hire specialists or you can rent it..

    During the performance of these works, it is necessary to adhere to the developed technologies and safety rules, then you can not only make a hole yourself without the involvement of expensive specialists, but also avoid injuries.

    With an ordinary drill or screwdriver

    If you do not have the tools described above, then this work can be done using a conventional electric drill or a powerful screwdriver.

    To complete drilling, you will need more time than using a hammer drill, but you can do everything yourself.

    In this case, in addition to the drill and drill, you will also need a punch. First, a small depression is made in the place of drilling using a punch and a hammer..

    After that, a working tool is inserted into it and begins to drill. If the drill stops, break hard areas again with a punch and continue working.

    Tips on how to drill a concrete wall with a conventional drill

    Residents of city apartments are familiar with the situation when it is required to drill a hole in concrete for household needs. Serious difficulties immediately arise. But one should not despair if it was not possible to quickly hang a cabinet, a sconce or a hanger – then it is described in detail how to drill a concrete wall with an ordinary drill.

    Tips from the masters

    When working, you need to use various devices. Concrete is often faced with different materials – each requires its own drill. Professionals are able to sharpen the drill so that it can pass freely through concrete and other materials, but this requires considerable experience. Before getting started, the following guidelines should be observed:

    • if the hole is obliged to penetrate deeper than 10 cm with its diameter more than 12 mm – work with a puncher;
    • start drilling at minimum speed, attaching the hammer function only after the tip is deepened by 4 mm;
    • make holes for dowels 10 mm deeper than the plastic housing of the fastener.

    When the drill jams, you need to remove it, and then use a punch to work out a hole, breaking the interfering stone.

    Tool selection

    Typically, a perforator is used to drill a monolith. However, this tool is far from always present, and it will not work if the following situations arose:

    • holes are required that penetrate shallowly into the monolith;
    • foam block wall;
    • the number of holes is small.

    Therefore, for practical use in an ordinary apartment, it is more advisable to drill concrete walls with an ordinary drill. When purchasing it, you need to take into account certain nuances:

    • the instrument must be percussion;
    • nozzles should be purchased.

    Drilling technology

    When analyzing the topic of how to drill a concrete wall with an ordinary drill, it should be understood that certain nuances must be taken into account for successful drilling:

    • If you need to get a deep hole with a large diameter, it is better to drill it with a hybrid drill with a hammer drill..
    • When making a hole for the dowel, you need to drill to a depth greater than the fastener. Then this stock will be clogged with dust when driving the dowel..
    • It is recommended to start drilling without turning on the percussion mode, setting the medium speed of the tool. After deepening the drill, the RPM is sharply increased while simultaneously adding the hammer mode. Doing so eliminates the possibility of drill movement due to vibration.
    • A lot of dust invariably appears during operation. It is advisable to turn on the vacuum cleaner, then the flying particles will be sucked in by it.
    • Clamping the drill, it is required to insert its shank all the way.
    • They work with a low-power drill no longer than a quarter of an hour. Then take a ten minute break..
    • If you wet the nozzle before drilling, the wear of its cutting solder will decrease..
    • If a through hole is made, reducing the speed at the final stage will help prevent concrete spalling from the opposite side..

    When the drill is jammed in the monolith, you cannot remove it by hitting with a hammer, trying to loosen it with pliers. The jammed part can be removed by drilling a small hole nearby..

    The procedure is successfully completed, when the final goal is reached, the instrument remains intact.

    Nozzles

    To drill a monolith with a drill, you need to purchase the appropriate nozzles. The following products are suitable for this:

    • Serrated crowns. They provide a drilling function. It is advisable to buy varieties in which separately soldered teeth, since they are made from durable metal alloys.
    • Diamond core bits. Such products will be able to make holes without hitting. These nozzles are improved, they allow you to get a hole much faster. The crowns are provided with curly cutouts, they have an abrasive structure on the edge. The master only needs to select the required length of the tool. In everyday life, varieties are usually used, the diameter of which does not exceed 120 mm..
    • Special drills for concrete. They freely manage to drill a monolith in which there is no reinforcement.
    • KS crowns with a cutting edge, the surface of which has a thermally applied diamond abrasive.

    When starting to use the purchased attachment, it is first recommended to check if there are electrical wires and fittings in the wall. It is convenient to do this with a device that detects the presence of metal. Thanks to this preparation, it will be possible to protect the nozzle from breakage, and the concrete wall will not be severely destroyed..

    When making any holes inside the concrete surface, the technology, as well as safety rules, should be scrupulously observed. In such a situation, even an ordinary drill will be able to drill the wall..
