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 quite reasonable question arises: how to drill concrete? Every home master who has ever encountered this problem has probably solved it for himself. But how much effort did it cost? First, some undertake to test the endurance of a drill, coupled with their own strength. And having not received the proper result, they leave the intention to make a hole in the concrete until the next time. As a result, the tool 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 drilling is difficult. Often you have to rest with drills on crushed stone, which is an integral part of concrete.
Making holes in concrete is necessary when:
How to drill concrete? It is possible to solve the problem of drilling concrete in 2 ways:
It is important to note that it is not possible to make a hole in a concrete partition with standard drills. Therefore, for work, drills with brazed plates, which are a high-strength pobedit alloy, should be prepared. They work great on brick and concrete. They are not used only to work with soft materials, because the one who wins them will not cut, but only crumble.

At home, when you need to make 2-3 holes on the concrete surface, a simple drill without a “blow” mode is quite suitable. Why, as the drill is immersed with a hole in the wall material, the concrete is knocked out 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 "stop" in the wall. Then the steel pin is installed in the recess and strikes on it with a hammer or a sledgehammer, trying to crush too dense places and deepen the hole further. At the same time, the rod is turned a little. After that, a conventional drill is again put into the process.
The manipulations described above are repeated over and over again until the required depth is reached. This method does not differ in speed, although it is quite suitable for making a couple of holes.
Another way is in concrete using universal diamond-coated drills. Their work is marked by high efficiency on metal, concrete and gravel. They are attached only to a standard electric drill and other tools without a vibration function.
Extreme care must be taken when working with a drill, otherwise it will instantly fail. The advice from professionals here will be as follows: to prevent overheating of the drill, it must be moistened periodically with cold water.

To drill a large number of holes, you will need a puncher or a drill with a “hit” mode, as well as drills with wins at the end.
The impact drill combines a rotational movement with a reciprocating movement, which allows it to be easily handled with lightweight concrete. For drilling load-bearing partitions made of concrete, a perforator will be the best assistant, since its main purpose is to punch exclusively concrete surfaces.
There are differences between a drill and a hammer drill:
Drilling of reinforcement caught in the thickness of a concrete wall is performed with drills for metal.
