How to drill a hole in a concrete wall with the use of

If you want to hang a lamp, shelf or other interior element in the room, then you will need to create a hole in the wall corresponding to the mount. There may be some difficulties, especially if you are facing concrete. In this article we will examine the correct methods of drilling such a strong surface.

General provisions

If you doubt the need to obtain this information, then let's first consider more specific cases in which you will need it:

When concrete drilling is required

• During the installation of plasterboard sheets. This is one of the most common methods of leveling walls, creating niches and multi-level structures.

• When installing furniture and other interior itemsrequiring reliable fastening.

• For air conditioning suspension. A sultry summer sooner or later may force you to take control of the microclimate of your home.

• In case of increase in the number of power points or their transfer. In this case, in addition to drills, additional nozzles will be required, but we will discuss this a little later.

• In the process of plumbing. It may also require fairly large holes that can pass through all the necessary hoses and pipes.

Why concrete needs a special approach

If you are convinced that the skills of drilling will certainly be useful in the future, then now let's see why concrete should be approached with special rules.

To do this, take a look at the structure of this material:

• Cement is not lower than four hundredth mark. Hardened cement is in itself a sufficiently strong surface, about which the standard drill will simply become dull.
• Sand. Its addition increases the density of the previous component, which makes processing even more difficult.
• Gravel. This is the most resistant element to any mechanical stress, which greatly complicates any drilling attempt.

Drill a concrete wall

How much does it cost to drill a hole in concrete? It is expensive enough to learn how to perform this task on their own. Of course, some cases may require the rental of special equipment or the hiring of specialists, but you must be able to make a seat under the dowel.

The instruction indicates the mandatory use of special drills with pobedits' nozzles, which allow crushing the stone coating, or diamond-coated cutters. Otherwise, there are some nuances that we consider.

Tip: do not use a poorest drill bit for drilling metal or wood, as it will not cut, but only break the surface.

Unstressed tool

If you need to create only a couple of holes, and there is no special tool with a blow function, then you can do with an ordinary electric drill or even a screwdriver.

Of course, you have to tinker, but you will save on the purchase of a punch.

1. Mark up the place of drilling in concrete.
2. We insert pobeditovy drill.
3. Drill until the product starts to get stuck.

Advice: it is recommended to wet the drill with water from time to time during work. This will protect it from overheating and improve the quality of the hole.

1. Next, we take a metal rod of suitable diameter, insert it into the hollow made and beat it with a hammer, trying to punch the top layer of concrete. After a positive result we continue drilling.

Tip: if you purchase a diamond drill, then you will not have to punch the hard concrete surface manually. Its price is, of course, much higher, but the work will be done accordingly faster and better.

Percussion instrument

If the amount of work you have is not limited to a small number of holes, then you should get a hammer drill or a perforator.

The impact function of these devices is carried out in the following ways:

• The design of the drill provides a kind of "ratchet". On the inner part of the planetary gear there are conical teeth, which are in contact with the counter part located on the “platform”, which stabilizes the central axis of the tool. Due to them, the vibration is carried out. Such a mechanical method has quick wear and a low impact.

• In the perforator, a pneumatic strike system was implemented, in which the force of the blow is injected due to air compression and the subsequent push of the piston. Wear is minimal, the result is excellent.

Thus, the need for manual knocking down of the concrete layer is eliminated, since the described electric tools perform this process simultaneously with drilling.

Cutting tool

How to drill a large hole in concrete? In some cases, you will be helped by a perforator, equipped with a special nozzle in the form of a crown, the teeth of which have a diamond coating. But if very large sizes are needed, then very powerful units with integrated cooling system will be required.

Here, as when cutting reinforced concrete with diamond circles, it is important not to hurry, to monitor the temperature of the equipment and the quality of the work done.

Conclusion

The drilling of concrete is undoubtedly different and has its own characteristics, which are associated primarily with its high strength. For its implementation it is best to use a perforator with a pneumatic impact system, which will allow you to break through especially hard layers of material.

A drill drill will also work, but using a conventional drill will require additional work. And with large diameters, diamond cutting with industrial equipment will do better.
