Many people live in houses with, and when it becomes necessary to make a hole in them, they encounter serious difficulties.
Don’t despair or be upset if you didn’t manage to hang a shelf, lamp or cabinet right away, read our recommendations and everything will work out.
There are several options with which you can drill yourself concrete wall.
Concrete structures They are highly durable, so drilling them yourself is quite difficult.
This is due to the fact that to create concrete products crushed stone is used and when you get on it while drilling, the process becomes very difficult.
The need to drill a concrete wall arises quite often; this is necessary for installing shelves, cabinets, air conditioning, mounting a lamp, or during or during the installation of beacons.
There are several ways to solve this problem:
To carry out this work, a regular drill is not suitable; it is necessary to purchase tools soldered with pobedite alloy.
It should be remembered that for walls made of relatively soft materials, you cannot use pobedite drills, as the holes will be uneven and the wall will collapse. It is also impossible to work with metal with such a tool.
To create holes large diameter or, diamond-coated annular 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.
As already mentioned, there are several ways to drill through a concrete wall; let’s look at each of them in more detail.
When using a hammer drill or impact drill, they must be switched to impact mode, a working tool with a pobedite tip is inserted and it must be directed perpendicular to the wall surface.
If drilling holes takes a long time, then The drill needs to be wetted periodically so that it does not overheat too much.
Once you have drilled to the required depth, you must pull the working tool back without turning off the hammer drill. To clean the finished hole from dust, you need to deepen and pull out the drill several times.
If you do not have the tools described above, then this work can be done using a conventional electric drill or a powerful screwdriver.
Drilling will take more time than using a hammer drill, but you can do it yourself.
In this case, in addition to the drill and drill bit, you will also need a punch. First, a small depression is made at the drilling site using a punch and a hammer.
After this, they insert the working tool into it and begin to drill. If the drill stops, break the hard areas again with a punch and continue working. 
Although a regular electric drill or screwdriver is not suitable for working with concrete, if you don’t have a hammer drill, you can make several small holes with these tools, but you need to use a spear-shaped drill with a carbide tip, usually used for tiles.
This is the most effective method, with which you can simply and quickly make a hole of the required diameter in a concrete wall.
To perform the above work, you will need special equipment consisting of the following elements:
There is no need to cool the drill during operation, 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 buy it for household use inappropriate. If it is necessary to make a hole of a large diameter, you can always invite specialists for this.
In order for you to be able to drill through a concrete wall correctly, you must have necessary equipment, Perform all work carefully and adhere to the following recommendations:
When performing the above work, you must adhere to the developed technologies and safety rules, then you can not only make the hole yourself without the involvement of expensive specialists, but also avoid injuries.

Small renovation work 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
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!
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 spray can is suitable for this. compressed air. 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!
Drilling into stone or hard concrete with a hammer drill is quite easy. labor-intensive process. In particular difficult cases, when you need to make a hole in a load-bearing wall or ceiling, it is still better to use a hammer drill (switching it to impact drill mode). You shouldn’t even try to use a drill when you need to drill holes for mounting on concrete floor profiles (during installation suspended ceiling). You will only waste time and become exhausted.
For work, concrete drills and drill bits (drills) are used. The concrete drill has a standard-shaped shank (like conventional drills for metal or wood) and is designed for an impact drill. Drill drills are designed for rotary hammers, which have shanks for an SDS chuck with a diameter of 10 mm or 18 mm.
The concrete drill is made from a special hard alloy; in addition, it has a soldered tip (made of a super-hard alloy based on titanium and tungsten). These drills can be used to drill concrete, brick, marble, stone, ceramics and other similar materials.
Most modern high-rise buildings it is built from monolithic concrete blocks, since this material is considered the most effective, durable and relatively inexpensive. Owners of apartments in such buildings sooner or later need to carry out repairs and improve their everyday life. In this case, it is impossible to do without drilling holes in the walls to install a lamp, cabinet, painting or other interior and design elements. It is at such moments that the question arises of how to drill and what equipment to use.
Without knowing drilling technology, you can waste your energy for a very long time and break an unsuitable tool without achieving desired result. When drilling concrete, you need to know the composition of this material. In slabs used in construction, with filler in the form fine crushed stone, as well as internal frames made of metal reinforcement, which serve to give the product strength and elasticity. If the drill hits a stone or reinforcement, many people, frustrated, simply abandon the hole. However effective ways There are still drillings.
It is necessary to drill structural holes in concrete with such types interior work, How:
Depending on the nature of the work, the depth and diameters of the holes can be different, ranging from a small hole for mounting a picture, to drilling large ones seats for sockets, switches or plumbing pipes. There are three ways to drill holes:
Depending on the chosen method and hole diameter, like:
It's important to remember that regular drills are not suitable for this job. For concrete, special drills with a diamond or pobedite tip, which has the shape of a blade, are used. These drills are specifically designed for rotary hammer drilling and are not suitable for creating holes in other types of materials.
If you are not carrying out large-scale repairs, and you need to make several small holes to install a lamp or picture, then a regular electric drill with a hammer drilling mode is suitable for this work. It is necessary to prepare a strong metal rod or a special punch that will match the diameter of the hole. An ordinary household drill cannot drill through concrete even in impact mode with a properly selected drill. To do this, a punch is used, which is periodically inserted into the hole and, using a hammer, breaks the solid elements of the wall.

This procedure is repeated until the hole depth matches the required one. If you are the happy owner of a powerful industrial drill, most likely, its power will be enough to do without a punch. It is worth noting that this method takes a lot of time and effort, but for several holes it is quite suitable. It is also necessary to remember that drilling concrete creates a significant load on the tool, and the drill must be stopped periodically to avoid breakage.
If you are undertaking major renovation work, you cannot do without a hammer drill. The hammer drill is specially designed for drilling heavy-duty surfaces and easily copes with drilling concrete. This tool allows you to use a large number of various attachments for drilling small and medium diameter holes for sockets, switches or water pipes.
To do this, use a special industrial equipment − complex device, consisting of elements such as:
Such equipment is used for drilling large diameter holes for ventilation shafts, cable routes and other communications. It is practically not used at home. This type of work is carried out by specialized construction crews, which consist of qualified personnel trained to operate such equipment.
Before drilling into a concrete wall, prepare a small container of water. It is necessary for periodic cooling of the drill, which may burst as a result of overheating.
During the drilling process, you can get into metal reinforcement. In this case, change the Pobedite drill to a regular one (diamond-coated) and drill through the metal rod. If the location of the hole is not fundamentally important, move a few millimeters to the side and drill a new one.
Before you start drilling the surface, be sure to make sure that there is no hidden cable inside, since damage to the power cable during drilling can lead to disastrous results. To do this, use a special non-contact device, which is usually made in the form of a screwdriver with a built-in LED. If there is a wire inside the wall, the light bulb will let you know.
Be sure to prepare individual means protection in the form of safety glasses, gloves and a respirator, since drilling in concrete produces dust and small particles that can damage the eyes or enter the respiratory tract.
How to drill or punch a hole in concrete, various methods.
Many experts know that drilling holes in concrete is not an easy task. Even if you use a Victory drill, it is not a fact that the hole will be drilled without problems.
What is the reason? The thing is that the right concrete wall (especially one built in Soviet times), consists of a quarter of reinforcing bars and stones. And only those who know the correct sequence of actions can drill through all this reliable splendor. I invite you to join the cohort of those who know by reading the detailed instructions.
Holes in concrete: step-by-step instructions
1. We take a punch and break the stones with it. This special drill, which you can easily find in any construction kit, is simply inserted into the drill and used in the same way as a Pobedit or diamond drill, the cost of which is not as high as it seems. As for the reinforcement, its cutting is carried out with a conventional drill.
2. If you are going to use a carbide drill, then to speed up the drilling process, I recommend using asymmetric sharpening. Before you start drilling a concrete wall, you need to make a mark with a drill with a standard sharpening. This will help give you the right start. WITH concrete wall A hammer drill made from a 6-8 mm drill, the end of which is sharpened like a dovetail, also works well. The drill must be constantly turned and struck. Drilling a hole for a socket with such a tool requires no more than 2-3 minutes.
3. Drilling or drilling holes in concrete should be accompanied by regular wetting of the working drill with water. This will help extend its service life. An elastic plastic bottle is often used as a reservoir.
4 . When you drill a hole in concrete ceiling, follow safety precautions. Plaster crumbs will fly under your sleeves, behind your collar and into your eyes. To protect yourself from them, you need to make an ordinary funnel out of transparent polyethylene film, which is placed directly on the drill.
5. When installing a chandelier, you will definitely have to drill a hole in the ceiling for subsequent sealing and installation metal hook. If you want to protect the plaster from almost inevitable crumbling, use a regular rubber ball, cut into two parts. A hole is made in one half of the ball, after which it is put on a bolt or punch.
How to punch a hole in concrete?
To punch a hole in a brick or concrete wall, you need to use special bolts, which are made from metal pipes. In the upper part, the bolts must be welded with steel rods using gas or forge welding. These rods will subsequently be struck. If the rods are not welded, the pipe will quickly wear out. On the working part, the teeth must be cemented with cast iron surfacing. It doesn’t hurt to separate them, which will help achieve greater stability of the bolts in operation. If you want to protect yourself from getting your tool stuck while punching holes, you need to rotate the bolt around its axis, remove it regularly, and clean it of concrete or brick dust. The bolt can be used as long as punching a hole in the wall 5 centimeters deep will not result in dulling or coloring of the teeth.
How to punch a hole using a scarpel?
Scarpel is a tool designed for drilling or cutting holes in brick and concrete walls, cutting niches, openings and grooves. Driving the scarpel into concrete may be accompanied by jamming, which should be avoided. If jamming does occur, then under no circumstances hit the scarpel from the side “in a bend.” This will lead to something irreparable. Modern scarpels, which help drill a hole of any size, are made from St.6 steel. The following requirements apply to them. When cutting a strip of steel marked St. 0, 5 centimeters wide and 4 millimeters thick, crumbled places, dents or signs of dullness should not appear on the working part of the tool. At the same time, the question of how to repair the resulting defects is simply not raised.
Mechanized hole punching
If a hole in a concrete wall cannot be made manually, mechanized punching using an electric hammer is used. This tool consists of a body and a striker holder, an electric motor and a converter mechanism. The use of an electric hammer is accompanied by the operation of a striking mechanism with the movements of the striker occurring as a result of the active actions of the converting mechanism. Mechanized punching using an electric hammer, without subsequent sealing, is characterized by a tip strike frequency of 2400 times per minute (standard load). Rental prices for such instruments are quite high.
