How to drill holes in concrete. How to drill a concrete wall with a regular drill: which tool and attachment to choose, practical tips. New or old tool
When improving an apartment, it becomes necessary to mount all kinds of objects on the walls and ceiling - photographs, paintings, lamps, mirrors, curtains, shelves, TV, baseboards and much more.
In order to hang a photograph or a small painting, of course, you should not drill into the wall. It is enough to hammer in a small nail. Not every carnation is suitable for this task. It is best to use dowels - nails from fastening brackets that secure computer network cables to walls. These cloves are of sufficient length, thick and hardened. It turns out to score even in concrete wall.
Performing the operation of drilling holes in walls with modern equipment with power tools will not present any greater difficulty if you know how to drill correctly. It will save you from unnecessary cleaning and keep your property intact if you use a jig for dust-free drilling.
How to drill a wall
A better tool than a hammer drill for drilling holes in brick and concrete walls has not yet been invented. But rarely does anyone have the luxury of having such an expensive tool on their household. Usually buy an electric impact drill.
Drill selection
At the time of buying electric drill Please refer to the following specifications below.
The power of the drill must be at least 600 W. Revolutions up to 2500 per minute and the ability to smoothly adjust them from zero to maximum. The presence of reverse rotation (switch for the direction of rotation of the drill clockwise or counterclockwise). The best chuck is a quick-release chuck; you won’t have to waste time clamping drills and constantly searching for a lost key. The diameter of drills clamped in the chuck is up to 12 mm.
The presence of a switchable hammer drilling function. Of course, when this function is enabled, the drill will not become a full-fledged hammer drill, but drilling walls will be much easier and faster, and here’s why. Brick, cement and concrete withstand static load - pressure very well. But they are easily destroyed by dynamic influences - impact. Karatekas, with a strong blow, easily break a brick in two with the edge of their palm. When drilling with a drill without a hammer function, there is simply pressure from the drill and it is difficult for the cutting edge to catch on to the material, so drilling is slow and the drill becomes very hot due to friction. Drilling with impact is completely different. Upon impact, the drill punctures a part of the material with its cutting edge, and, falling with an impact into the formed recess, breaks off a portion of particles of the material. Something like chiselling is happening.
Drill selection
Walls made of wood, plasterboard, and foam concrete can be successfully drilled with an ordinary drill. For walls made of brick, stone or concrete, you need a carbide drill. It differs from steel by cutting edges made of carbide material welded onto a regular drill, usually Pobeda. Less commonly, artificial diamond.
The pobedite insert is clearly visible at the end of the top drill. It is enough to have 2 Pobedit drills with a diameter of 6 and 8 mm on the farm.
Using drills with pobedite surfacing, you can drill a hole no more than 10-15 cm deep. For drilling to greater depths, for example, to drill through a wall, use a drill. Drills for drilling brick and concrete walls are up to one meter long and are designed for drilling holes only with a hammer drill. Even the cutting edges of the drill are made not sharp, but rounded to increase their wear resistance. A drill with a hammer drill function can also be successfully drilled with a drill.
Drills come with a shank diameter of 10 and 18 mm, with special grooves of the SDS+ or SDS-max standard for fastening, but they also clamp well in a regular jaw chuck. The standard and diameter of the drill are stamped on its shank.
If you need to drill through a thick wall, for example half a meter, then the passage is carried out in several stages with drills of the same diameter, but of different lengths. This is necessary for safety and faster drilling. First, drill the wall with a 20 cm long drill to a depth of 10-15 cm, then with a longer drill to a depth of 30-35 cm and finish drilling with a 50 cm long drill. The drill for such work must be powerful enough. Of course, the drill is not designed for such a load and its use is permissible only in exceptional cases. To perform this type of work, it is better to rent a real hammer drill.
How to drill a wall
Before you start drilling a wall or ceiling, you need to make sure that there are no holes in the plaster under the intended place. electric wires or other cables. Otherwise, you can damage the electrical wiring and get under voltage yourself.
How to avoid getting caught in a wire
It is necessary to inspect the wall for the presence of a switch or socket. Usually, wires extend upward from them in a vertical direction to distribution box. But verticality is the ideal case. This rule is rarely observed in practice by electricians, saving wire, often hidden wiring laid diagonally. Here's an example of this. When I made repairs and moved the counter to another place, after removing the old wallpaper the following picture opened. You can clearly see how the wire leading to the meter was laid.
But still, the wire will run from the switch to the nearest box. The wire will also go from the chandelier to the nearest box.
Usually the wires are recessed to a depth of no more than 10 mm. To check, use a blunt instrument, such as a screwdriver, to dig into the wall to this depth. If no wires are found, then you can start drilling. And yet, just in case, up to a depth of 20 mm, you should not press too hard on the drill and after deepening every couple of millimeters, visually check whether the wire is caught.
There are special devices that allow you to determine the location of wires in the wall. Here are some of them that are not expensive, made in China, but nevertheless works well. It also has a metal detector function, which allows you to identify the location of metal reinforcement in concrete walls. The device allows you to find copper electrical wiring at a recessing depth of up to 10 mm. Electrical wiring made from aluminum wires, is detected only in metal detector mode.
Wiring detection is indicated by a flashing LED and an intermittent beep. In metal detector mode, when detected, the diode lights up constantly and the sound produced is continuous. There is a sensitivity regulator, the finder is powered by a Krohn-type element. Such a device is especially necessary when installing suspended and suspended ceilings, because bearing structures They are mounted on self-tapping screws near the ceiling, exactly where electricians usually lay the wiring.
Drilling holes in reinforced concrete
Brick walls can be drilled with a Pobedit drill without much difficulty. We decided on the location, attached the jig and, pressing hard on the drill, drilled a hole. It happens that you come across burnt bricks in the wall, which drills more slowly, the dust is not red, but black. The main thing is to drill at low speeds (200 - 400) with the impact mode turned on, pressing harder on the drill handle, and make sure that the drill does not overheat.
I bring to your attention a great video where you can see how a brick wall is drilled using an ordinary drill with a hammer drill function and a drill with pobeditovy surfacing. IN brick wall a selection was made for the box to install an internal electrical outlet.
As you can see, drilling a brick is not at all difficult. Be careful, When drilling for a long time, the drill heats up to high temperature And If you touch it, you can get a severe burn. It is necessary to periodically stop drilling and dip the drill in water.
Unless the concrete wall or ceiling is made of 600 or 500 grade cement, it drills just as well as brick. In domestic construction, only grade 400 cement is used. In old houses, sometimes there are columns and ceilings made of high-strength concrete. They are very difficult to drill and take a long time.
In the production of concrete blocks and wall panels for strength, they install iron reinforcement welded together mutually perpendicularly, which is corrugated rods with a diameter of 8-15 mm, and add granite crushed stone. A pobedite drill is not able to overcome such an obstacle. But there is a simple solution. When, while drilling, the drill suddenly stops going deeper, it means it has encountered reinforcement or granite. The reinforcement can be successfully drilled with an ordinary drill. If you don’t have a simple drill on hand and it is permissible to move the location of the hole, then you can move it diagonally up or down. Granite pebbles in concrete crumble when struck with a drill or narrow chisel inserted into a hole with a hammer. After each blow, to prevent the tool from jamming in the concrete and to make the work go faster, it is necessary to turn it a quarter turn. After removing the obstacle, drilling continues with a Pobedit drill. For a drill with a hammer drill, granite stones are not an obstacle and can be drilled successfully.
Drilling tiles
To drill into tiles with a carbide-tipped drill not specifically designed for tiles, it is necessary to first remove the glaze after marking the drilling point.
This is done very simply, with a core, and if it is absent, you can use an ordinary self-tapping screw or even a thick nail with a sharp end to chip off the glaze in the place of the future hole with very light blows and then drill like a brick wall at low speeds.
Drilling large diameter holes in the wall
With equipment ventilation ducts and hoods, it becomes necessary to make a hole in the wall large diameter, for example 18 cm. Sometimes you want to hide an electric meter in the wall, and then you need to make a niche in the wall.
At home, this problem can be solved using a carbide drill. The outline of the future hole is drawn on the wall with a pencil. On the outside of the marking line, holes are drilled with a carbide drill with a diameter of 8-12 mm with a distance between the edges of the holes of about 10 mm. For a hole in the wall with a diameter of 18 cm, you will need to perform about 30 drillings with a drill diameter of 10 mm. Next, a sample of the wall material is made using a chisel and hammer. With a smaller drill diameter, the edges of the hole will be neater, but you will have to drill more holes.
If the wall is thick and the length of the drill is not enough to achieve through drilling, then you can drill in two stages.
If it is possible to drill a wall on both sides, then first drill as described above on one side of the wall, then in the geometric center of the resulting sample, a hole is drilled in the wall to reach out, that is, through. Relative to the resulting hole, markings are made on the opposite side of the wall and the operation is repeated.
If it is not possible to drill a thick wall on both sides, then you will have to do drilling and sampling in two stages. From the marking line on the outside, another line is drawn at a distance sufficient so that after the first sampling in the wall and further drilling, the drill can go deeper into the made niche without touching the edges of the wall.
To reduce the labor intensity of the work, it is better to immediately purchase a drill of sufficient length.
Drilling depth limiter
To control the depth of the resulting hole during the drilling process, you can put a piece of cambric (tube) of the required length on the drill bit until it stops in the chuck.
If you don’t have a suitable cambric on hand and you need to drill a small number of holes, then you can use ordinary PVC insulating tape, winding several turns of it. This simple device will speed up your work and save you from having to stop drilling to measure the depth of the hole.
Jig for drilling holes without dust
Due to the heterogeneity of the walls, especially those made of brick, the drill often “leads” away from the intended place and if there is more than one hole, then the suspended shelf does not hang horizontally or, even worse, it is impossible to hang it, since the installed dowels do not coincide with the mounting ones loops. You can use a jig in the form of a sheet of plywood with a pre-drilled hole, but when drilling due to vibration it can also move and again the result will not be what was expected. But there is simple technology, allowing you to drill two or more holes strictly in specified locations.
Precise hole drilling
It turns out that the problem can be solved very simply by gluing a sheet of any sandpaper with glue or double-sided tape to the entire area of the side of the conductor that is attached to the wall. At the same time, the adhesion of the jig to the wall surface increases many times over, and during drilling, the specified accuracy of positioning of the jig is ensured. The hole will appear exactly at the marking location.
Depending on the weight of the product and the density of the wall, you have to drill holes for dowels different diameters, usually 6 or 8 mm. For the versatility of the jig, it is necessary to drill several holes of the desired diameters with an ordinary drill.
To top it off, attach a plate to the end of the base of the conductor at a right angle. Thanks to this improvement most of drilling products will remain on this shelf, which will prevent contamination of the wallpaper and reduce the scattering of dust in all directions.
The proposed device is also indispensable when drilling holes for attaching skirting boards. Drill a hole in the jig at a given height from the shelf. When drilling, place the shelf on the floor and all the holes will be exactly at the required height from the floor, which will guarantee a tight fit of the plinth to the floor surface.
Sometimes you have to hang a product on the wall, for which you need to drill several holes in the wall and maintain the distance between them with greater accuracy. If the wall is brick and plastered, then do it without a conductor precision drilling impossible.
To make a jig for precision drilling, a board, sheet of plywood or metal is suitable. After marking in the sheet, it is drilled with an ordinary drill required amount holes. Consider the case for fastening the product with two screws. One hole is drilled with a diameter equal to the diameter of the drill that will be used to drill the wall, the second with a diameter equal to the diameter of the self-tapping screw. After the jig is made, the first hole is drilled in the wall using the jig for the precision drilling described earlier, and a dowel is driven into the hole.
The conductor is screwed to the wall with a self-tapping screw into the hammered dowel and leveled using a water level so that drilled holes were on the same horizontal line.
Thanks to the use of a simple jig, which can be made in a few minutes from any available material, the holes were created exactly at a given distance from each other.
Using the same technology you can drill and whole line holes at a greater distance from each other. In this case, first the outer holes are drilled using the technology described above, the jig is screwed with two outer self-tapping screws, and then all other holes are drilled.
The proposed options for conductors are convenient when renovating an apartment, when dirt is common everywhere.
However, when the renovation is completed and cleaned up, drilling becomes stressful. You don’t want to stain your carpets and furniture with concrete or brick chips and dust.
Drilling without dust
When drilling walls, especially the ceiling, flour and grains of sand from the drilled material scatter throughout the room. This happens because an impeller is installed inside the drill to cool the engine, which, rotating, sucks air into the drill body from the side of the handle, and throws it out heated in the chuck area. This measure makes it possible to make a drill of greater power with small dimensions and protect the drill mechanism itself from dust. And the question of how to protect your home from dust when drilling is left to the owner to decide. I present simple design allowing you to drill without dust.
The drilling jig for dust-free drilling is a modified previous version, but the shelf is replaced by a part cut off from plastic bottle. A piece of 9-11 ply plywood measuring 80×150 mm is cut out, and a hole with a diameter equal to the diameter of the drill plus 1 mm is drilled at a distance of 30 mm from the edge along the center line. On the side where the sandpaper will be glued, a trapezoidal cut is made with a depth of 2-3 layers of plywood. The sample will serve as a kind of air intake during drilling.
A part is cut off from a plastic bottle so that the remaining part can be attached to the conductor. The width of the base of the conductor is selected based on the size of the bottle. I took a square bottle, but any 1.5 liter bottle will do. Insulating tape is wound onto the threaded part of the neck of the bottle until a size equal to internal diameter suction pipe of the vacuum cleaner. When the bottle is bent, holes are formed to form the required configuration. We close them with pieces of the remaining plastic from the bottle and secure them with a stationery stapler. You can close them with tape. There is no need for tightness here. Gaps of a few millimeters will not matter, since the suction power of even a low-power vacuum cleaner is excessive.
Then, using a furniture stapler, the formed part of the bottle is secured along the perimeter of the end of the base of the conductor, on the side where the sandpaper is not glued. We make a hole in the bottle for the drill. It is better to use the melting method, since the edges forming the hole will become thicker and last longer. I melted it with a soldering iron. You can melt a hole by heating it gas stove until red with a nail.
Connect the vacuum cleaner and turn it on minimum power suction, we do test drilling.
The result will make you very happy. You will not find a single speck of dust in the circle or brick flour on the drilling surface!
Those who live in houses with concrete partitions are well aware of the situation when it is necessary to hang an object on the wall. At such a moment, a completely reasonable question arises: how to drill concrete? Every House master Anyone who has ever encountered this problem has probably solved it for themselves. But how much effort did it take? First, some people try to test the endurance of a drill coupled with on our own. And without receiving the desired result, they leave the intention of making a hole in the concrete until next time. As a result, the instrument has to be repaired, and the shelves continue to gather dust in their corner. However, there are ways, you just need to find out for yourself and use them correctly in an emergency.
Concrete structures are very durable and difficult to drill. Often you have to rest drills against crushed stone, which is integral part concrete.
It is necessary to make holes in concrete when:
- furniture arrangement;
- facing works;
- additional installation of electrical wiring;
- hanging the air conditioner;
- installation of plumbing fixtures.
How to drill concrete? The issue of drilling concrete can be resolved in 2 ways:
- an impact drill or a hammer drill with a special drill called a Pobedit drill;
- diamond drilling.
It is important to note that it is not possible to make a hole in a concrete partition using standard drills. Therefore, for work, you should prepare drills with soldered plates, which are a high-strength pobedite alloy. They will do an excellent job with both brick and concrete. Do not use them only for working with soft materials, because the one who wins will not cut them, but only crumble them.

What is better to use at home?
At home, when you need to make 2-3 holes on the concrete surface, a simple drill without the “impact” mode is quite suitable. Why, as the drill immerses with the victorious wall material the concrete is tapped with a strong metal pin (punch) corresponding in size to the diameter of the recess.
In particular, a punch is used when the tool begins to “lock” in the wall. Then the steel pin is placed in the recess and struck with a hammer or sledgehammer, trying to crush the overly dense areas and deepen the hole further. At the same time, the rod is turned slightly. After which a regular drill is put back into the process.
The manipulations described above are repeated again and again until the required depth is achieved. This method is not very fast, although it is quite suitable for making a couple of holes.
Another way is in concrete using universal diamond-coated drills. Their work is celebrated high efficiency on metal, concrete and crushed stone. They are attached only to a standard electric drill and other tools without a vibration function.
When working with a drill, extreme caution should be used, otherwise it will instantly fail. The advice from professionals here would be this: to prevent overheating of the drill, it must be periodically moistened with cold water.

What to do when the amount of work is large?
To drill a large number of holes, you will need a hammer drill or a drill with an “impact” mode, as well as drills with winners at the end.
The impact drill combines rotational motion with reciprocating motion, which allows it to be easily controlled lightweight concrete. For drilling load-bearing partitions made of concrete, the best assistant is a hammer drill, since its main purpose is to punch holes exclusively on concrete surfaces.
There are differences between a drill and a hammer drill:
- The first is to drill holes of small diameter (no more than 12 mm);
- Using a hammer drill, larger recesses are drilled.
Drilling of reinforcement found in the thickness of a concrete wall is performed with metal drills.
When making holes in materials that are characterized by increased strength, which include concrete, brick, etc., drills for metal work are useless: their cutting part quickly becomes dull. In such situations, it is better to use a concrete drill, which is characterized by a number of distinctive properties when compared with those used for drilling metal.
Types and parameters of concrete drills
The peculiarity that distinguishes concrete drills is that their cutting part is equipped with tips made of a special alloy, the hardness of which is very close to the hardness of diamond. Thanks to your unique characteristics such an alloy was called “win.” Pobedit concrete drills are the most durable tool for processing this material.
Among concrete drills, there are two main categories:
- concrete drill bit for a drill, the design of which has a cylindrical or multifaceted configuration;
- a tool for working complete with a hammer drill, having a cylindrical shank, on which the designation SDS-plus or SDS-max is placed.
Home craftsmen often have questions about how to choose equipment and tools for making holes in reinforced concrete structures. To solve this problem, a hammer drill with concrete drills for an impact drill is optimally suited. Drill bits of this type are often called drills and are divided into three main types:
- auger, with which you can drill holes of considerable depth;
- spiral-shaped (they can make holes of large diameter);
- flat, which allows you to obtain holes with small diameters and depths.
Thanks to this design feature, like a thickening on the shank, the drills are installed in the tool chuck by simply clicking into place. Typically, they are chosen by professional builders and execution specialists. installation work to obtain holes whose diameter is in the range of 4–30 mm.
In the event that the question arises about how to drill concrete, obtaining a hole of a larger diameter, choose a crown-type tool. It forms holes with a diameter of up to 12 cm. Core drills for concrete are also divided into several categories:
- diamond drills for concrete in the form of a tube or crown, which are fixed on a solid-section rod (diamond coating is applied to the working part of such a tool, which is why it is called a diamond drill);
- pobedit drills having a similar diamond design, but differ from them in the material used to make the teeth on the cutting part (these teeth are made of pobedite).
The need for a core drill for concrete arises when it is necessary to prepare seats For electrical outlets and switches, carry out communications and perform other work related to the need to obtain large holes and recesses.
The choice of drill for brick and concrete is also determined by the diameter and depth of the holes being formed. A diamond or pobedit drill can have the following diameter and length ratios:
In the table below you can see a simple pattern: the larger the diameter, the longer the length of the concrete drill. This is explained by the fact that a long and thin tool cannot withstand the perceived loads.
There are several rules, following which will allow you to carry out drilling work on concrete as efficiently as possible.
- If you don’t know how to drill a concrete wall with a drill, stock up on different drills, including those designed for metal work. Each type of drill is designed to perform specific work: for brick - for drilling a brick wall, for concrete - for forming holes in concrete structures, for ceramics - for drilling surfaces finished with ceramic tiles. However, when deepening into the structure of the material being processed, the tool may rest against metal reinforcement, then it must be temporarily replaced with an appropriate drill. Some home craftsmen, when making holes in concrete structures, sharpen the drills they use so that they can also handle metal. However, in order to endow a drill bit with such versatility, it is necessary not only to have the appropriate knowledge, but also to have extensive experience.
- Under no circumstances should the concrete drill be allowed to overheat. It is necessary to take breaks every fifteen seconds and cool the instrument naturally, without using water or any other liquids.
- The structure of concrete necessarily contains hard stones, upon which the drill cannot move further. Such a stone must be crushed with a chipper and only then continue drilling.
- If you need to make a hole in a load-bearing concrete wall or ceiling, it is best to use a hammer drill, which will solve this problem as efficiently as possible.
- To drill a hole in a ceramic coating on a wall or floor, you must turn off the impact mode of the drill or hammer drill, otherwise ceramic tile it will simply collapse. When working with such surfaces, it is possible to use concrete drills.
- Inexpensive drill bits for concrete, made from not very hard material, should be sharpened periodically. For this you can use the corner grinder, on which the diamond blade is installed.
The most popular brands of tools for drilling concrete
Drills that are used to perform concrete work on modern market represented by both foreign and domestic brands. Prices for such an instrument often depend on the reputation of the manufacturer who made it.
How to choose a drill for concrete? It should be understood that higher prices for these products are fully justified, given their guaranteed high quality and longer terms operation.
On the list foreign companies that offer concrete drill bits to consumers High Quality, the following manufacturers should be highlighted:
- Makita;
- Bosch;
- Metabo;
- stayer;
It should be borne in mind that the high-quality products offered by these companies are quite expensive.
Particularly noteworthy is the tool from Bosch, which is distinguished by its four-spiral design, which allows it to easily remove processing waste from the hole being formed.
Bosch drills of the CYL-9 Multi series are universal and, in addition to concrete, are used for drilling brick and wood
Among concrete drills from domestic producers and companies from the CIS countries and China should highlight products manufactured under the following brands:
- "Interskol";
- "Bison";
- "Enkor";
- Uragan et al.
Pobedite drills of the mid-price category provide sufficiently accurate drilling, but have limited period services
It should be noted that drills made in China can be reliable if they are quite expensive. We must understand well that a high-quality tool cannot be too cheap, because only the best materials and innovative technologies are used for its production.
The low cost of individual copies of such drills can be explained by violations technological process their manufacture, which is allowed by some manufacturers, as well as the use of cheap and low-quality materials. In the modern market, you can also encounter counterfeits, which are quite difficult to distinguish from original products. There is an opinion among experts that fakes have more dark color, since some stages of their production are performed incorrectly. However, when deciding to choose a drill for concrete, pay attention to the cost of such a tool, which should not be too low.
To save on purchases, you can purchase drills in sets, then the price for an individual copy will be slightly lower.
Distinctive features of concrete drills
There are several criteria to distinguish a drill for concrete work from tools for drilling other materials.
Working part shape- Drills for woodworking have the sharpest tip, which initial stage processing is pierced into the material.
- The tip of the tool for working with metal is cone-shaped and does not have a pointed part.
- The fairly blunt tip of concrete drills is made of pobedit plate.
When making renovations in an apartment or house, the question of drilling the wall always arises. Can be used different instruments depending on the purpose of the hole and the material from which the surface is made.
There are nuances when working with each tool, especially when drilling a wall. How to do it right correct hole, and what recommendations to follow?
Drilling holes in the wall correctly: general rules and recommendations for what to drill
In order to correctly drill a wall, you need to take into account the material from which it is made, based on this you need to select a tool.
- When working, hold the tool correctly. For example, a drill should be held straight in your hands and enter the surface in a vertical direction;
- for convenience, use an additional handle;
- Depending on the surface material, select the necessary drills.
The material of the tool used to perform the work must be harder than the surface being drilled.
Tools for different surfaces:
- concrete, stone, brick wall - use a carbide drill, usually a Pobedit one;
- metal – metal drill;
- tiles, ceramic tiles – special drills for these materials, it can sometimes be replaced with a concrete drill with Pobedit surfacing;
- Chipboard, wood - for holes smaller than 10-12 mm, a metal drill is suitable; for larger ones, special wood drills are used.
Tools for work
For work they use different tools, the main ones: drill, hammer drill, screwdriver. There are nuances to using each.
Drill
The tool is suitable when you need to make several holes. You can use a regular drill. When plunging a Pobedit drill into the body of the wall, sometimes you need to break the concrete with a punch that matches the diameter of the hole. This is necessary when the drill starts to get stuck in the surface, bumping into areas that are too dense. The process is quite labor-intensive.
For greater efficiency, you can use universal drills that have diamond coating. They are installed only on a conventional drill or on a tool where the vibration function is disabled.
For large-volume work use impact drill and drills with pobedit tips. They are designed for holes up to 12 mm. The drill is suitable for working with metal and concrete.
To prevent the tool from overheating, you need to periodically moisten the drill with cold water.
Hammer
Hammer – universal tool. It can be used to make a hole in a wall made of wood, tiles and concrete.
The tool has several functions - drilling, hammer drilling and impact mode. To make a hole, you need to select the desired drill depending on the surface and carry out the work by selecting the mode.
Screwdriver
A screwdriver is one of the most popular tools for repairs and construction work. With its help you can tighten and unscrew screws, drill wood, metal, chipboard, plywood, tiles, plywood, lightweight concrete.
Which nozzles to choose
A specific nozzle is used for each material:
- concrete, brick, stone - drill with a carbide plate or pobedit;
- tiles, glass - cone-shaped drills with diamond coating;
- metal – spiral drill with a cylindrical cone;
- wood, drywall - for holes of different diameters, drills are used: feather, ballerina, screw, saw bits for wood;
- foam concrete - pobedit drills.
Is it possible to do without a drill and hammer drill?
Make a hole without a drill or hammer drill, but not in a concrete wall. To do this you will need a bolt or a punch.
A bolt is a pipe with teeth at the end. The punch has an end in the form of a chisel or a tetrahedron.
The working end of the tool is applied to the place where the hole will be. By opposite side it, you need to strike hard, rotating the tool after each turn.
How to drill without dust: options, the better
Construction work is always accompanied by dust and debris, but using some recommendations and tips, it can be significantly reduced:
- During operation, the hammer drill leaves a slight dust, so that it does not fly around the room. Use it at the same time construction vacuum cleaner. Some brands of tools have a built-in vacuum cleaner, which makes the task easier;
- using a drill, it is best to either make a jig on the end or a bag, or make an envelope under the hole so that the debris falls into it.
How to drill holes in a brick wall: choosing tools and attachments
To make a hole in a brick wall, a hammer drill with a drill or an impact drill are suitable; the latter is most often used. Its power must be at least 600 watts, the minimum number of revolutions is from 2500 per minute. It is best to use a drill with continuously adjustable power and a quick clamp function.
Using the hammer drilling function, the drill becomes identical to a hammer drill. Increases speed and ease of operation. To make a hole in a brick wall you need to use the dynamic impact method. Without this, the drill will not be able to engage inner part bricks
The drills must be victorious. If through drilling is necessary, a drill is used
How to drill a load-bearing wall in a panel house with a hammer drill
In the majority panel houses The walls are made of concrete; to make a hole with a hammer drill, you need to use pobedit drills.
In addition to them, you can use special crowns. They have soldering around the circumference. When using them, you need to disable the hammer drill's impact function.
Experts use diamond drilling, for this it is necessary powerful equipment and skills.
How to properly drill a reinforced concrete pipe with a hammer drill
When using an impact drill for reinforced concrete, you need to use the “perforator” mode and pobedit drills. First, the hole is made smaller, then larger. The drill needs to be cooled periodically.
Important! When working with concrete, you need to avoid hitting the reinforcement, otherwise the drill will break. Using a special device you can check where it is located.
How to make a hole in a concrete wall with a drill
It is difficult to drill into a concrete wall with a conventional drill. You need to install Victory drills and select low speeds. A dowel is inserted into the desired location to help the tool pierce the surface. Next, drilling should be alternated with striking the dowel.
The drill must be constantly cooled, otherwise it will burn.
If the drill does not have a speed control, then it will not be possible to make a hole.
How to make a hole in a concrete wall in an apartment with a drill
For a small hole, you can use a punch. Most conveniently, it can be made from a drill, 8 mm in diameter. The end is sharpened sharply. The drill is placed in the right place, rotated, while simultaneously hitting it with a hammer. Wet the drill periodically to make it work longer.
When working with tools, you must follow safety rules and general recommendations:
How can I repair a large drilled wall?
You can seal unnecessary holes in the wall using a special construction mixture. It provides strength and durability. The composition must be selected depending on the area and type of defect.
Using putty, you can level the surface, including concrete. There are several types of putty:
- cement – used in external and interior decoration, suitable for concrete. Durable and moisture resistant. It dries for a long time and often in a mesh pattern, which requires re-application;
- gypsum - used in dry rooms, is not resistant to water and is afraid of temperature changes. Does not crack when applied, so you can immediately apply a thick layer;
- acrylic – finishing. It needs to be applied in a thin layer, so it is suitable for small defects.
Neither mixture is used to seal through holes.
Polyurethane foam – universal material. There is one-component (used without preparation) and two-component (when used, a construction gun or mixer is used).
When applied, the foam increases in volume and fills the required space. It hardens and gives high-quality density. Deep holes can be sealed.
Suitable for eliminating large defects. It has good adhesion, is frost-resistant, strong and durable.
When you decide to make a hole, carefully read the rules and recommendations. Choose a tool, depending on the composition of the surface, and a drill. If you are not confident in your own skills, then entrust the work to specialists.

When conducting self-repair In an apartment or house there is a need to make a hole in a concrete wall. It can be non-through (for fastening) or through (for engineering communications). Let's take a closer look at how to drill a concrete wall using various tools.
For this, it is best to use a hammer drill. This is a professional tool, so you may not have it at hand. But buying one just for repairs is expensive. Therefore, you can use a regular household drill with an impact function.
Tool selection
The best option for drilling concrete walls is a drill:
- power 600 W;
- rotation of the working body up to 2500 rpm;
- diameter of clamped drill up to 12 mm in a quick-release chuck;
- with the obligatory presence of reverse.
Drill
To drill into concrete, you need a drill made of very hard metal. The most commonly used carbide products are those with pobedite or diamond edges. The first option is cheaper, and performance qualities will not yield to the second.
But it is necessary to take into account the fact that using a drill you can make a hole in the wall no more than 15 cm deep. For a through hole you will need a drill.
Boer
To make a hole with a drill, you need a drill with a shank diameter of 10 or 18 mm. The shape of the drill shank has grooves, but they are also perfectly clamped with drill chucks. If there is a need to drill through a thick concrete wall, then it would be correct to use drills of different lengths.
For example, first drill a hole 15 cm deep, then replace the drill and drill a depth of up to 35 cm, then up to 50 cm. True, the deeper you drill into the wall, the more power the drill requires.
Checking the presence of electrical wiring
First of all, it is necessary to determine the drilling location. In this case, the main point is not to get into the electrical wiring. According to building law, all wires are located only vertically and horizontally. And if there is a socket in front of you, then its wire runs vertically to the junction box. True, embarrassments do happen. This is when electricians decide to save cable or wire. Therefore, there is a possibility that the wiring is not laid as it should.
As you can see, the wiring is located horizontally and vertically.
You can use another option. To do this, use a screwdriver or similar tool to pick out the concrete or plaster at the drilling site. Depth – 5 cm. If you don’t hit the wire, then you can drill.
Drilling process
To make a hole correctly, you need to follow several simple rules. Firstly, for this you need to keep the tool speed to 400. Secondly, experienced craftsmen It is recommended to periodically lower the drill into cold water. Please note that the drill removed from the concrete wall is very hot, so do not get burned.
Possible obstacles
During the production process, a reinforcing frame made of metal reinforcement with a diameter of 8-12 mm is installed in load-bearing wall panels. Plus everything in concrete mortar can lay crushed stone or gravel. All this is an obstacle to drilling concrete walls.
If the drill hits something hard and the process itself stops, then most likely you hit either a reinforced frame or crushed stone. What to do in this case?
Stone or metal?
First of all, you need to determine whether there is metal or stone under the drill tip. If the depth of the hole is small, then this can be confirmed visually. If it’s deep, then pick up a drill or a metal pin with a diameter slightly smaller than the hole, insert the tool inside and hit the free end with a hammer.
If after a few blows you feel that the instrument has broken something and is moving deeper, then it means it was a stone. If nothing happens and the tip of the pin is dull, it means there is reinforcement underneath.
We go around the fittings
It’s clear what to do with the stone. That is, you slowly break it and continue to drill a hole with a drill. But the reinforcement can be drilled with a regular metal drill. Simply replace the Pobedit drill in the chuck with a regular one, drill a hole through the reinforcement, then continue working with the Pobedit tool.
If you don’t have a regular drill at hand, you can shift the direction of the Pobedit drill at an angle (down or to the side). Sometimes it works. By the way, if you use a hammer drill and a drill, then crushed stones are not a problem for these two tools. The drill simply crushes them with impact actions.
Old-fashioned way
More recently, when pobedit drills were in great short supply, and drills with impact functions were new, they used ordinary drills using unusual technology.
To do this, a pin was made from one drill. Its end could be flat, like a screwdriver, or it could be made conical, like a tap. Periodic drilling and striking were carried out. That is, first a hole was drilled, then a pin was inserted into it, which was struck with a hammer. Then again drilling, then blows. In essence, the person performed the percussion functions of a hammer drill.
The best option
And yet, the question of how to drill a concrete wall may remain completely unanswered if a few words are not said about diamond drills. This is the highest quality instrument, although expensive compared to the Pobedit one. Experts consider them universal, because they can drill almost any material. By the way, the drills themselves are not diamond, they cutting edge Diamond coating applied.
The most important thing is that such a device can be drilled using a drill without an impact function. You need to work with a diamond drill correctly. It, like other types, must be periodically moistened in water to reduce the temperature. High speed are also unacceptable here.
