Who lives in houses with concrete partitions, is well aware of the situation when it is necessary to hang any object on the wall. At such a moment, a quite reasonable question arises: how to drill concrete? Every home artist who has ever encountered this problem has certainly solved it for himself. But how much effort did it cost? First, some are taken to check the endurance of the drill, along with its own strength. And without getting 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, it is just necessary to find out for yourself and use them correctly in an emergency.
The drill for drilling of a concrete wall.
What do experts recommend?
Concrete structures are very durable and can be drilled with great difficulty. Often have to rest on the drill bits in the rubble, which is an integral part of concrete.
It is necessary to make holes in concrete when:
- furniture arrangement;
- facing works;
- additional wiring installation;
- hanging air conditioning;
- installation of sanitary devices.
What to drill concrete? To solve the problem of drilling concrete is possible in 2 ways:
- a percussion drill or a perforator 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 the concrete partition with standard drills. Therefore for work it is necessary to prepare drills with the soldered plates representing a high-strength beat alloy. They will do an excellent job with bricks and concrete. They do not use them only for working with soft materials, because they will not be cut, but only minced.Back to table of contents
What is better to use at home?
The correct angle of sharpening the drill for drilling in concrete.
At home, when you need to make 2-3 holes on the surface of the concrete, a simple drill without the “punch” mode is also suitable. For this purpose, as the drill is immersed in the wall material, the concrete is hammered with a durable metal pin (punch), corresponding in size to the diameter of the recess.
In particular, the piercer is used when the tool begins to “stop” in the wall. Then the steel pin is installed in the recess and blows are performed on it with a hammer or sledge hammer, trying to crush too dense places and deepen the hole further. Rod while turning a few. After that, the process again start up the usual drill.
The manipulations described above are reproduced over and over again until it reaches the required depth. This method does not differ in speed, although it is quite suitable for making a pair of holes.
Another way is to drill holes in concrete with universal diamond-coated drills. Their work is marked by high efficiency on metal, concrete and rubble. They are put only on a standard electric drill and another tool without the function of vibration.
When working with a drill should be extremely careful, otherwise it will instantly fail. The advice from professionals here will be this: to prevent overheating of the drill, it must be periodically moistened with cold water.Back to table of contents
What to do when the amount of work is large?
Comparison of holes in diamond drilling and drilling with a perforator.
To drill a large number of holes, you will need a punch or a drill with the "punch" mode, as well as drills with victories at the end.
At the impact drill, the rotational movement is combined with reciprocating, which allows it to simply be controlled with lightweight concrete. To drill the bearing walls of concrete, the best assistant will be a puncher, since its main purpose is to punch only concrete surfaces.
There are differences between the drill and the hammer drill:
- holes of small diameter are drilled first (no more than 12 mm);
- the perforator is drilled larger recesses.
Drilling of reinforcement that has fallen into the thickness of the concrete wall is made with drills for metal.Back to table of contents
What is drilled to a considerable depth?
Anyone who, by the nature of his activity, regularly encounters the procedure of drilling holes in concrete, uses special devices for this purpose:
- drilling drive;
- various d drill bits;
- powerful electric motor;
- guide post attached to the base.
Diamond drilling provides the ability to make indentations with significant d, about 40 cm. The procedure is fast, efficient, silent and does not make a lot of dust. To the drilled place the machine receives water, which cools the diamond crown and washes dust.
Grades of concrete M 250 - M 500 can be drilled with a diamond drill.
Diamond drilling is unique in that the holes after it are obtained with the correct configuration with clear contours, and the inner walls are well polished. The recesses can be performed in a variety of protective structures and at different angles relative to the horizontal. The likelihood of chipping and cracking on the surface is completely excluded. Only the material that falls under the drill is destroyed.
Diamond drilling is carried out by companies specializing in this. And when absolutely necessary to make a hole of a large size, you can call the masters with special equipment. And it is not necessary for a pair of holes to acquire a diamond drilling rig.
So, we found out that for home drilling of concrete surfaces it is quite enough to use a drill and a perforator.
For other cases, there are firms that specialize in drilling with large hole diameters.
