Holes for installing electrical cables, electrical equipment, electrical networks and pipes can be made mechanically or manually - that is, by punching.
In order to punch a hole manually, you will need a bolt. The bolt is installed strictly perpendicular to the wall. Then you need to hit it with a sledgehammer, while turning it around its axis. We must not forget to periodically clean the holes from dust and pieces of brick.
If you need a rectangular hole, then use a jackhammer or a scarpel. The top brick is beaten off first, and only then the next one is beaten off. This is done using a scarpel hammered into a vertical seam.
But still, this method is very labor-intensive and time-consuming, so it is advisable to use a mechanized method.
At the moment, production does not stand still and a huge number of pneumatic, drilling, and electric machines are produced: hammers, hammer drills and furrowers. It has become possible to use modern tools equipped with carbide plates and diamond drills.
When considering the option of drilling with a drill, you need to remember that not every hole can be made with it. The diameter of the hole plays a role here; for a drill it does not exceed 50mm, and in some cases even 30mm
There is another important point encountered in the process of drilling concrete with a drill, this is the reinforcement in the wall. If the drill hits metal, the cutting tool immediately burns out. It can also pass tangentially to the reinforcement, and it gets pinched, as a result of which drilling stops and it is impossible to continue.
A tool called “Carbide bit” suggests the ability to make holes with a diameter ranging from 50mm to 450mm.
It is possible to install adapters, but there may be several disadvantages: if the size of the bit that is installed on the hammer drill is larger than the existing one, there is a possibility of tool breakage; drilling will pose a huge danger.
When working with a pobedite bit, there is a chance of bumping into the reinforcement, in which case the teeth of the bit will most likely break or become dull. The crown can cut through thin reinforcement using carbide tips. And secondly, when drilling with a crown, you need to take into account the depth of the crown bowl.
Of course, you can make a through hole using a crown for concrete sockets, and alternately use a crown and a pick on a hammer drill. Those. once you have gone deeper, move on to the crown. Then you knock out the core of the hole with a pick, and so on, until you get the desired result. And finally - remember, when drilling concrete using carbide bits, there will be a huge amount of dust in the room.
And finally, the most commonly used drilling at the moment is diamond drilling. It has many advantages.
1. Versatility. A diamond bit can handle both concrete and reinforcement (which is an integral part of concrete structures). Everything is explained very easily: the hardest mineral in nature is diamond.
2. Diamond crown design. Due to its tubularity, the crown makes it possible to drill holes of the required depth. You simply drill out a solid piece. Also, thanks to this tubular design, you make the hole clear and precise in diameter, and there is no deviation during runout.
3. Possibility to use water cooling of the diamond bit during operation. Dust does not accumulate during the drilling process, which greatly improves working conditions and results.
4. Versatility in use. A diamond crown can process not only concrete, but also brick, porcelain tiles, and granite.
And of course, like everything else, it has its drawbacks. Here they are quite natural, this is the cost of this method. Here you need to take into account the cost of both the crown itself and the tool on which it is installed.
Minor repairs periodically become a necessity in every home. Drilling was no exception. To implement it correctly, you need tools, experience and a little time, otherwise it will be an unwanted expenditure of money. To avoid the latter, we have prepared for you an article on the topic: “How and with what to drill into a concrete wall?” Let's look at all the important points.
How to drill into a concrete wall
New or old tool
Remember, if your wife asks: “How to drill a hole in the wall to install an outlet there?”, then it’s time to resort to using a hammer drill!
Additional Information
To prepare the wall for drilling a large-diameter hole, use a thin drill to make a small notch in the center of the mark. This will allow you to later find a comfortable stop with the tool so that it does not slip off. You need to press the drill moderately, without applying significant force, otherwise there is a risk of breaking the drill.
Periodically blow dust out of the hole, this will increase the reliability of the fasteners being installed. A rubber bulb or a can of compressed air is suitable for this. Blowing with your mouth is not recommended, as dust will get on your face and eyes (as a last resort, use safety glasses).
We hope our information resource helped you, and the question of how to drill concrete no longer bothers you. Good luck!
When making renovations in an apartment or house, the question of drilling the wall always arises. You can use different tools 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 make the right hole correctly, and what recommendations should you 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, sometimes they can be replaced with a drill for concrete 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, an impact drill and drills with pobedit tips are used. 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
A hammer drill is a 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 repair 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 - conical drills with diamond coating;
- metal – spiral drill with a cylindrical cone;
- wood, drywall - drills are used for holes of different diameters: 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. On the opposite side of 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 a construction vacuum cleaner at the same time. 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 a dynamic impact method. Without this, the drill will not be able to engage the inside of the brick.
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 most panel houses, the walls are made of concrete; in order 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 impact function of the hammer drill.
Specialists use diamond drilling, which requires 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 building 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 exterior 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 is a 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.

Concrete is a durable and reliable material. Many, if not most, buildings are constructed from cast-in-place or precast concrete. As a rule, holes for laying utilities, pipelines, as well as recesses for installing electrical and low-current fittings are provided during the process of forming concrete structures. But their location often does not suit the owner of the premises, and holes have to be drilled at new points. Let's try to figure out how best to do this.
Choosing a tool
Initially, you should determine which tool is better and more efficient to drill into a concrete wall. In a global sense, the choice is small - an impact drill or a hammer drill. But there can be many nuances, since power tools come in different power and functionality, and there are also many attachments for them. Therefore, you should define goals and objectives, and then decide which tool may be needed. So:
- You don't need a lot of force to screw a small screw into the wall for a picture. In this case, you can drill into a concrete wall with a conventional drill equipped with a drill bit with a Pobedit tip.
- When a small amount of work is expected, and the diameter of the holes to be punched does not exceed 12 mm, then an impact drill should be chosen.
- A hammer drill is used to drill holes of large diameters, as well as any size, in concrete, but in significant quantities.
The advantage of a rotary hammer over a drill, even with an impact function, is not only greater power and endurance. This tool uses not only drills of various sizes and qualities as a working tip, but also drill bits. This is the main device that can be used to drill a hole in concrete for a pipe.
Professional installers, when punching large-diameter holes in concrete, use special units, which include:
- high power electric motor;
- durable bracket with guide structure;
- drilling drive;
- drill bits with a diamond working area.
Such equipment allows you to make a hole or recess with a diameter of up to 40 cm in a concrete wall.
What will win more effectively or a diamond?
When you need to make only a few holes for a construction dowel, and there is no hammer drill at hand, then using a regular drill with a Pobedit drill bit is quite possible. Also, this option is best suited if the working surface is concrete, but made of cellular material. The hammer drill will destroy it. But when working with a Pobedit drill, remember that it is short-lived and requires periodic replacement. In addition, such a drill can “drill” into concrete. Then he needs to be helped manually with a punch and a hammer.
Drilling into a concrete wall with an impact drill equipped with a diamond-coated drill bit is much more effective. Diamond drills are somewhat more expensive than Pobedit drills, but they also last longer. And another important point. Unlike Pobedit, a diamond drill punches holes not only in concrete and stone, but also in ceramic tiles, porcelain stoneware and metal. When working with a diamond tool, it is not scary to stumble upon a reinforcement frame in the wall. It is better to purchase drills as a set, which includes drills of various diameters. This is more profitable than buying them individually.
When a hole with a diameter of 35 to 120 mm is drilled in a wall, diamond bits are used as a cutting device. They are carbide-tipped steel rings on a diamond-coated working area. For domestic purposes, crowns with a diameter of 6.8 cm are usually used; holes of this exact diameter are needed for installing electrical sockets and switches.
How to drill concrete correctly
Punching holes, like any other, requires preparation. In addition to tools and accessories, you should stock up on water to cool drills and bits. Before drilling into concrete with a drill or hammer drill, inspect the wall for:
- hidden heating pipelines, water supply;
- electrical wires, cables.
The search is carried out with a metal detector; identified communications are marked along their entire length. It is better to disconnect the electrical wiring on the work surface. Further:
- Mark the locations of future passages. If large diameter holes are expected, then the designation is made along the contour and axes.
- The depth of the hole for the construction dowel is 8-10mm greater than its length.
- To obtain a more accurate result, you need to drill concrete correctly. This means that the start of drilling should be done at low engine speeds.
- After a small depression is created, the speed is increased and the tool is switched to impact mode.
- If possible, provide a water supply to the drilling site. If this option is not available, periodically moisten the drill with water in a pre-prepared container.
- If drilling with a drill is carried out in one position of the tool, then when drilling with a crown, the hammer drill must be slightly rocked. This way, waste will be easily removed from the resulting hole and the crown will not jam.
The most difficult obstacle that has to be overcome when drilling a concrete wall is the reinforcement cage. The diamond bit cuts steel rods of small diameter independently. When drilling with an impact drill, metal drills should be used to remove the reinforcement.
Wear safety glasses and a respirator. It is convenient to collect the resulting dust with a vacuum cleaner. Every 15 minutes of drilling, give the tool a break for about the same period of time. To continue working, moisten the drill with water.
Concrete structures, walls and ceilings are not uncommon in our houses and apartments. In multi-story construction, they are generally used with particular frequency, since houses with concrete walls are the most reliable. The reliability of concrete is determined by the good strength of such a material, which is achieved through the use of the correct components of the concrete mixture and high-quality work done on its construction.
And so we are proud of our strong walls. But usually it becomes necessary to drill a hole in this very wall. Moreover, this may be needed quite often, for example:
- when finishing walls and ceilings;
- during the installation of air conditioners;
- when installing plumbing;
- when building furniture;
- when working with electrical wiring and its installation;
- the need for holes for mounting under a picture or other interior items.
As you can see, there are many reasons to drill into a wall. The main thing is not only to do the job well, but also to make your life easier by using the right good tool. Which one can you choose to drill concrete?
It would seem that what’s wrong with this: just take a regular drill and drill. But no, in fact, many difficulties may arise in the process of completing this task. Firstly, concrete walls are very strong and difficult to pick up, and secondly, their structure is heterogeneous, and you can easily risk falling on crushed stone or a piece of reinforcement. You can get stuck with an ordinary concrete wall for a long time and end up not drilling anything.
How to drill a hole?
The answer to this question will not be too complicated. The fact is that drilling a concrete wall, as mentioned above, is an extremely difficult process. To solve this issue, it is worth using one of two types of tools: either a hammer drill or a drill.
Both will be good in certain conditions. I'll explain why. It is best, of course, to use a hammer drill: it is intended specifically for concrete walls and common practice is to use it. After all, a hammer drill easily breaks through both stone and concrete surfaces. Another advantage is the ability to drill large-diameter holes, which a drill cannot do.
But, if you have a wall made of foam concrete in front of you, or you need to drill several small holes, a drill will do just fine. In this case, the hammer drill can split the surface of the wall, which is not very successful. But, as already mentioned, do not count on large holes, only with a diameter of no more than 12-15 cm. In addition, drilling a concrete wall has its own nuances, which we will consider below.
How to drill through a concrete wall with a regular drill?
Let's talk a little about drilling with a regular drill. So, let's start with the fact that the usual one is unlikely to work here. Those. theoretically this is, of course, possible. But in practice it is extremely difficult. In this case, it is necessary to use a special Pobedit drill for working on concrete with a tip coated with a hard alloy composition.
The best way is to use a special impact drill. How is it different from the usual one? The fact that in such a drill the movements of the drill are carried out due to special ratchets with teeth interacting with each other. This type of drill is not difficult to use to get high quality work done. To do this, simply switch the drill from normal rotational mode to impact rotation mode.
But it doesn’t matter what type of drill you use, as long as it is important to use specialized attachments. Attachments (crowns) are sold in two configurations: for impact or non-impact drilling.
The classification of nozzles is as follows:
Serrated drill bits with impact function. A concrete wall can be drilled with such crowns with a cutting edge made of separately soldered teeth made of durable alloys. For quick-release drill chucks, these drill bits have SDS tails. Their strength is so high that it is possible to cut metal, but the impact mode contributes to their destruction, creating unacceptable loads. That is why such drills are used to drill a hole between the reinforcement of a reinforced concrete slab or brick walls.
Diamond bit for non-impact drilling. These are more modern attachments that simplify the task several times better than conventional ones. The abrasive edge with cutouts on them is created by diamond sputtering or sputtering of corundum sand. As you know, diamond is distinguished by its unprecedented strength. That is why it can easily cope with the reinforcement of a concrete wall. With such a nozzle you can make a hole at least 1.5 meters deep and more than half a meter in diameter. This type of nozzle is already used by professionals, but nozzles with a diameter of up to 100 mm can easily be used in domestic conditions.
Crowns standard KS. Crowns with diamond crystals embedded on the cutting edge. They can be used for slabs, rocky soils, and monolithic concrete structures made of high-strength grades. They can easily replace toothed carbide crowns.
Based on your conditions, you can safely select the necessary drill bit for the drill and drill a hole. But there are also a number of recommendations for working with a conventional drill that is not equipped with an impact function.
To do this, you start drilling into the wall, but periodically stop. You need to drive a pointed drill into the concrete surface with your hands and destroy the concrete with metal punches. We take our drill or chisel, other metal devices of the appropriate and required diameter and hit them with a hammer/sledgehammer. Rotate the punch periodically. Then take the drill again.
Please note that when drilling a hole in a concrete wall with a regular drill, you risk breaking the tool. Be sure to give a low-power drill a rest. Drills also tend to heat up, so they need to be cooled with water. In this case, take a break every 10-15 minutes of work, leaving the same amount of time for the instrument to rest.
