How to save money on a hammer drill and drill a concrete wall with a conventional drill? How to drill a concrete wall with a conventional drill: which tool and nozzle to choose, practical tips How to drill a concrete wall with an impact drill
Many people live in houses with, and when it becomes necessary to make a hole in them, they encounter serious difficulties.
Do not despair and be 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 drill a concrete wall yourself.
Concrete structures are highly durable, so drilling them yourself is quite difficult.
This is due to the fact that crushed stone is used to create concrete products, and when you hit it during drilling, the process becomes very difficult.
The need to drill a concrete wall arises quite often, it is necessary for the installation of shelves, cabinets, air conditioning, fixing a lamp, at or during the fastening of lighthouses.
There are several ways to solve this problem:
- using a hammer drill or a powerful impact drill;
- conventional electric drill or screwdriver;
- diamond drilling.
To carry out this work, an ordinary drill is not suitable; it is necessary to purchase tools soldered with a pobedit alloy.
It should be remembered that for walls made of relatively soft materials, it is impossible to use pobedit 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 holes of large diameter or, diamond-coated ring 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.
What is the best drilling
As already mentioned, there are several ways to drill a concrete wall, we will consider each of them in more detail.
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 drilling holes takes a long time, then drill needs to be moistened periodically so that it doesn't overheat.
Once you have drilled to the required depth, it is necessary to pull the working tool back without turning off the perforator. To clean the finished hole from dust, it is necessary to deepen and pull out the drill several times.
Standard drill or screwdriver
If you do not have the tools described above, then you can do this work with a conventional electric drill or a powerful screwdriver.
To perform drilling, you will need more time than using a hammer drill, but you can do everything yourself.
In this case, in addition to a drill and a drill, you will also need a punch. First, a small indentation is made at the drilling site with a punch and a hammer.
After that, insert a working tool into it and start drilling. If the drill has stopped, break the hard sections again with a punch and continue to work. 
Although a conventional electric drill or screwdriver is not suitable for working with concrete, but if you do not have a hammer drill, then you can make several small holes with these tools, but you need to use a carbide-tipped spear drill, it is usually used for tiles.
Diamond drilling
This is the most effective method by which you can simply and quickly make a hole of the required diameter in a concrete wall.
To perform these works, you will need special equipment, consisting of the following elements:
- electric motor;
- a stand that is securely fixed to the base;
- drill bit.
During operation, it is not necessary to cool the drill, as water is supplied to it, which not only cools the tool, but also prevents dust from forming.
If specialists work, then together with the specified equipment they use a vacuum cleaner, with which they remove dust and water.
Because the price of such equipment is very high, then it is not advisable to buy it for domestic use. If necessary, make a hole of a large diameter, for this you can always invite specialists.
In order for you to be able to properly drill a concrete wall, you must have the necessary equipment, perform all work carefully and adhere to the following recommendations:
- without a hammer drill, work can be done with an impact drill or drilled with a screwdriver;
- do not buy cheap drills, as their winning tip disappears very quickly and they fail;
- instead of a punch, you can use a victorious tool, with one you will break rubble, and with the second, inserted into a conventional electric drill, drill;
- to work with concrete, the perforator must have an SDS-plus cartridge;
- consider the placement of the reinforcement to determine where it is, you can use a metal detector if the reinforcement is exposed, it is necessary to prevent rust;
- to work 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.
Conclusion
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 involving expensive specialists, but also avoid injuries.

Each of us at least once in our lives faced the task of hanging a shelf, a picture or another object in our apartment, and since the walls of the domestic housing stock are predominantly concrete, this task requires some skill and the necessary tools at hand.
Sometimes this procedure takes on a non-trivial character, because the walls can have a heterogeneous structure, including iron reinforcement or crushed stone, and the usual concrete is quite durable, so today we will tell the reader how to make a hole in a concrete wall and what is needed for this. .
First of all, you need to decide on the tool with which we will drill the wall - the choice is between a drill and a puncher. If you have only one of these tools at your disposal, then the agony of choice disappears by itself, but for those who plan to rent equipment, we recall that a rotary hammer is a device designed specifically for this type of work, and therefore in most cases it will be better. And the available range of outlet section sizes is much larger than that of a drill.
But the drill also has its advantages, for example, when it comes to foam concrete structures - a puncher will simply crumble such a base. Remember that the drill must be an impact drill, a non-impact one will not bring results and will most likely be damaged. Therefore, if you are wondering whether it is possible to drill through a concrete wall with a drill, then know that the answer depends on the type of drill and the material of the wall itself.
Drill
An impact drill differs from the more common unstressed one in that the movement of the drill in it is carried out with the help of special ratchets with teeth. It is very elementary in use, it is enough just to put the tool in shock rotation mode and get down to business. Even more important for the success of the component are the nozzles suitable for our task - drills, read their list in one of the paragraphs below.
In addition to choosing the right tool and consumables for it, we note a couple more features of drilling concrete walls with a drill. If you do decide to work with a hammerless drill, then stop while drilling and help with your hands, driving a sharpened drill with a hammer, then continue to use the drill. If the drill is low-power, then let it rest more often to avoid overheating.
In general, nothing is impossible, and with desire and diligence, you will surely be able to cope with the wall, having tools that are not quite suitable for this in the arsenal, but remember that if the surface does not lend itself, it is better to postpone the idea if you do not want to say goodbye to your drill.
Perforator
With this tool, everything is simple:
- To begin with, we check its serviceability, clean the shaft shaft from debris.
- Insert the drill until it clicks
- We bring the tool perpendicular to the wall and start drilling, pressing a little. The drill, in the case of a long process, is moistened from time to time with plain water so that it does not overheat.
- If the drill is stuck, then we simply take it out of the puncher, insert a tool of a smaller diameter and try to release the stuck object with it, expanding the hole.
What drills are suitable
As promised, we are considering drills suitable for our venture. We will fit the following: 
- Concrete drills with a pobedite tip - do a good job with the material due to the cutting edge of the teeth based on hard alloys. The margin of safety is enough even for drilling metal, but the impact mode quickly renders them unusable. If you need to make a hole between the reinforcement - this is the best option.
- Diamond crown for hammerless drilling - a modern nozzle that opens the material of any strength due to diamond coating.
- KS crown - diamond crystals have settled in them on the cutting edge, which makes them something in between the two previous types.
Drilling in concrete is very difficult, everyone who has had to deal with a similar problem will confirm this. In order to adequately overcome the resistance of a resistant material, you need to know some of the features of concrete drilling, plus be able to apply knowledge in practice. So, let's find out how to get out of the situation without problems.
What kind of drill to drill concrete
To drill a concrete wall, craftsmen use drills with a pobedite tip.
A simple drill will not cope with such a task. If you need to make a small hole (less than 13 mm in diameter), then a drill is used, and in other cases, a puncher. It is much more productive than a drill due to the presence of a device with an impact function and a higher drilling speed. When a hammer drill is not at hand, an ordinary drill with a carbide drill with an asymmetric sharpening is also suitable.
Before starting work, it is necessary to outline the place of drilling with a core. It is also desirable to minimize the spread of dust throughout the room by placing a simple device on the punch cartridge - a cap from a tin can. Most of the dust will settle in it. In order for the plastic dowel to go into the hole made to the end, experts recommend making a recess a centimeter longer than the size of the fastener itself.
In the process of rotation in concrete, the drill heats up due to friction, which leads to a decrease in its working properties, so the drill is periodically moistened in machine oil or ordinary water.
For high-quality drilling, it is preferable to choose a tool equipped with a building level. If such a contraption is not provided in the puncher, it does not matter, an ordinary small level, fixed to the body with electrical tape, will also do.
It happens that you need to drill through the concrete, and the drill at hand is too short. Then a blind hole is drilled from the inside for the entire length of the existing drill, and a magnet is placed in the resulting socket. On the reverse side, the location of the first one is determined by another magnet, and drilled at the intended point.
If metal reinforcement interferes with drilling, then change the drill bit for concrete to something that is designed to work with metal. Then continue with the same drill.
Before drilling a concrete wall, make sure that the penetration into the material will not damage any communications.
The use of a punch to make holes is already considered obsolete. However, with small volumes of work, it is indispensable due to its affordability. With its help, drilling is carried out by percussion or in the usual way. But this method has a significant drawback: in the process of operation, the vibrations that inevitably arise from the "grooving" of the tool lead to unwanted defects in the finish. And if, in addition, the hammer drill is very powerful, then the consequences of actions for the structure are simply unpredictable. To reduce vibrations, new modifications of modern rotary hammers have been developed.
Nowadays, diamond drilling equipment is more often used, especially in large-scale construction - the holes in the concrete are even, clear, while the drilling machine practically does not create noise and almost does not form dust and debris. The shockless method does not make chips, it is also possible to avoid the formation of cracks in concrete. And the main plus of diamond drilling is that in addition to fast drilling of concrete, it can easily cope with reinforcement.
To obtain holes in thin concrete partitions, a punch is used: it is made from an 8 mm drill, the end of which is sharpened under the “swallow's tail”. The drill needs to be turned and hit with a hammer.
When drilling in the ceiling, so that the concrete crumbs do not fall asleep to the eyes, it is recommended to attach a protective funnel to the tool.
To fix the screw in concrete, a piece of nylon is driven into the hole. Then it is slightly melted with a hot metal (nail), after which a screw is screwed in. Kapron hardens and firmly holds the mount.
A dowel substitute can be a piece of copper or aluminum tube. It is compressed to the required size, inserted into the hole and screwed.
The repair process in an apartment includes a lot of work related to creating holes in the walls: for this, tools of various designs and capacities can be used. Many craftsmen and those who are going to do the repair themselves want to know how to drill through a concrete wall with a conventional drill and whether it is even possible. For such work, a puncher is usually used, but it is not always suitable for this, moreover, if the tool has to be bought, then its cost is much higher than that of a drill.
Features of choosing a tool
In most cases, it is better to use a hammer drill: it has increased power, is designed for punching hard surfaces, and allows you to make large holes in diameter. The use of the tool is inappropriate in the following cases:
- the need to drill a wall to a depth of 10-12 mm;
- working with, which crumbles when processed with a perforator;
- in the work it is required to make no more than 10-15 holes.
Before drilling a wall, it is important to choose the drill itself: it should not be unstressed, since this variety is ineffective when drilling concrete, the nozzle and cartridge become unusable almost immediately. The nozzles themselves must be victorious, designed for concrete work, the tip - with a hard-alloy 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.
What nozzles to choose?
Before drilling a hole in a concrete wall, you need to select a nozzle of the appropriate design. The following types are used for work:
- Tooth crowns impact type, designed for drilling. When working with concrete, it is recommended to use varieties from the teeth of a separate soldering, made from the most durable metal alloys. Many hole saws are equipped with SDS tails for installation in drills with keyless chucks. Drills are well suited for concrete walls, however, when in contact with metal, they can begin to collapse, so before drilling a reinforced concrete wall, you need to check that there are no reinforcements used for reinforcement in the place of work.
- Diamond crowns, which are designed for non-impact 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 grit or corundum. Before you make a hole in the wall, you just need to choose the right 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-crowns, which have a cutting edge with crystalline diamond particles. These bits are used for most hard walls, including drilling into concrete slabs, exterior walls, and masonry.
Before drilling or a partition, you need to make sure that during the work the wires or cables will not be touched, if any are laid inside.
How to 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 need to be concreted.
When using a pobedite nozzle in the course of work, it is required from time to time to use a metal punch, which is selected according 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, the use of diamond crowns can serve as an alternative: a drill equipped with such nozzles will not get stuck in concrete.
Action algorithm:
- Before drilling a hole in the wall, you need to install the desired nozzle, after making sure that the tool is in good condition and the integrity of the drill.
- Drilling concrete is required carefully; when using low-power equipment, the duration of continuous operation of the drill should not be more than 10-12 minutes. If drilling is delayed in time, you need to take breaks so that the motor of the device cools down.
- After it became clear to drill a concrete wall, 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 seen on the video:
If you encounter a stuck drill, you can not remove it by force: this leads to breakage of the fixture, as a result of which the tip will remain in the concrete. The nozzle needs to be disconnected, select a crown of reduced diameter and use it to pull out the stuck element.
Before you decide how to drill concrete walls and start work, 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 (hammer drill);
- if holes are made for plastic dowels, the depth should be 7-10 mm larger than the size of the fastener, 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 increased torque, and the shock mode is turned on when the drill goes 2-4 mm deep;
- the dust that appeared 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 slipping of the handle and goggles so that the crumb does not get into the eyes and does not damage the mucous membrane.
In most cases, a concrete wall is drilled with a hammer drill, without 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 a wall, you should pay attention to victorious crowns: with such a drill, using a drill, you can easily punch a hole up to 10-12 cm deep.
Small repairs periodically become a necessity in every home. Drilling is no exception. For its correct implementation, tools, experience and a little time are needed, otherwise - an undesirable cost of money. To avoid the latter, we have prepared an article for you on the topic: “How and with what to drill a concrete wall?”. Let's take a look at all the important points.

Remember, if the wife asks: “how to drill a hole in the wall to install an outlet there?”, Then it's time to resort to using a puncher!
Additional Information
To prepare the wall for drilling a large diameter hole, make a small notch in the center of the mark with a thin drill. This will allow you to find a convenient stop with the tool in the future so that it does not slip off. You need to press the drill moderately, without making significant efforts, otherwise there is a risk of breaking the drill.
Periodically blow dust out of the hole, this will increase the reliability of the installed fasteners. For this, a rubber bulb or a can of compressed air is suitable. Blowing with your mouth is not recommended, as dust will get on your face and eyes (in extreme cases, use safety glasses).
We hope our information resource has helped you, and the question of how to drill concrete does not bother you anymore. Good luck!
