A hole in a brick wall. How to drill a concrete wall with a conventional drill: expert advice. Order diamond drilling of concrete with a thickness of a meter and more than a meter

A structure whose surface damage is far from easy to drill. But if such a need nevertheless arose, then using special equipment and following some rules, it is still possible to do this. And now about everything in more detail.

General Provisions

Let's start by looking at why a concrete wall is not drilled by conventional methods. And everything lies in the structure of such a durable material:

Demolition work always starts from the top, and the hardest thing is to knock down the first brick. Walls made of bricks, blocks or blocks can easily be torn down, cutting only welds. This work will greatly facilitate the drilling of a large hole with a masonry hole mounted in a strong drill. Thus, we will get rid of the first layer of bricks, and the next will be relatively easy to remove. If the target hole does not reach the ceiling, then the destruction of the wall should begin 5-10 cm higher to create a reinforced concrete lintel.

For large spans, the jumper reinforcement must be selected by a specialist. Facing the lintel requires the installation of formwork, such as slabs filled with concrete. Attention! During demolition, do not use high-power electro-pneumatic hammers, because the vibration caused by them can damage the plaster on the remaining walls or ceiling.

As you can see, the action of all components is aimed at increasing the strength properties of the finished product. Crushed stone, about which their cutting edges are instantly blunt, is especially critical for conventional drills.


And with all the complexity of processing a concrete wall, the need for this can arise very often.

In the case of dividing partitions, which are not sure that they are also not a support for the ceiling or a higher partition, and the width of the building exceeds 1.5 m, the destruction should go from the center of the hole, in one row in both directions. At the same time, make sure that there is no excessive deflection of the ceiling by measuring the distance from the floor to the ceiling in the center of the wall.

To make the hole even, an angle grinder with a diamond blade will be provided. The cuts made by him will facilitate the removal of the ends of the bricks without damaging the rest of the wall. The way the sides of the hole are finished depends on whether the door is installed there or whether the door is left open.

For example, if necessary:

  • Hang a shelf on a wall or some other furniture interior.


  • Drywall.


  • Electrical wiring, installation of new outlets and switches. At the same time, reinforced concrete is also cut with diamond wheels to lay the wire.


  • Plumbing connection.


Execution technology

We figured out the need and the difficulties that arise, now we will consider how to drill correctly concrete wall.

Tool selection

First of all, we will decide what to drill a concrete wall. certainly not suitable.

Choose from the following options:

  • Beat Drill Tips. But keep in mind that in addition to rotation, an impact function will also be required.


Tip: you should not use a winning cutting tool for drilling iron or wood, as it will crush them.

  • Diamond Coated Drills. Such edges can cut a stone even without a blow, but their price is much higher.


But the question of how to drill a concrete wall is not limited to the choice of consumables.

You also need to decide on the tool:

  • Conventional drill. Only if you do not have anything more suitable and you need to make only 2-3 holes. And in this case it is necessary from time to time to punch a layer of concrete with a steel pin with your own hand.
  • Impact Drill. It will cope with a small amount of work even if the diameter of the required holes does not exceed 13 mm. The fact is that a blow in such an apparatus is carried out due to a metal “ratchet”, which, under intense load, quickly erases.


  • Hammer drill. It will master large volumes and can even use special nozzles in the form of crowns, which are ideal for drilling sockets for sockets. In it, the blow is carried out due to the piston system, which is much more powerful and less likely to fail than the "ratchet" of the drill.


To summarize and give a final answer to the question, what is better to drill concrete walls, the following generalized table will help:

Work

Now let's figure out how to drill a concrete wall. To do this, take a punch, as a clear winner of impromptu competitions.

The instruction for its operation is as follows:

  1. Check the shaft shaft for debris. If one is found, delete it.
  2. Insert the drill until it clicks. Moreover, in some models it may be necessary to pull the slider part of the “nose” of the instrument onto itself.
  3. We bring it strictly perpendicularly and begin to drill, slightly pressing on it.

Tip: from time to time moisten the working part of the drill with water. This will protect it from overheating and extend the service life.

  1. During drilling, the drill may get stuck. In this case, do not try to loosen it in order to pull it out, so you can break off the tip. Simply remove the tool from the machine, insert a drill of a smaller diameter and try to expand the hole with it and release the captured product.
  2. Keep an eye on the equipment, letting it cool.

Conclusion

We looked at how to drill a concrete wall; the process itself is not so complicated. The main thing is to choose the right tools and follow some rules while working. The most practical and rational solution will be to use a hammer drill with drill bits.


The video in this article will provide you with additional information regarding the material presented. Be careful, and you will succeed!

Concrete structures, walls and ceilings are not uncommon in our homes and apartments. In high-rise construction, they are generally used with special frequency, since houses with concrete walls come out the most reliable. Reliability of concrete is determined by the good strength of such a material, which is achieved through the use of the correct components of the concrete mixture and the quality of work done on its construction.

And here we are proud of our sturdy walls. But usually there is a need to drill a hole in this very wall. And it may be needed quite often, for example:

  • when decorating walls and ceilings;
  • during the installation of air conditioners;
  • when installing plumbing;
  • when embedding furniture;
  • when working with electrical wiring, its installation;
  • the need for holes for mounting under the picture or other home decoration.

As you can see, there are many reasons to drill a wall. The main thing is not only to do the job well, but also to make your life easier using the right good tool. Which one can you choose to drill concrete?

It would seem that this is so: just take a regular drill and drill yourself. But no, in fact, in the process of performing this task, many difficulties can arise. Firstly, concrete walls are very durable and hard to take, and secondly, their structure is heterogeneous, and you can easily risk getting on gravel or a piece of reinforcement. Get stuck with ordinary concrete wall  You can not drill anything for a long time in the end.


How to drill a hole?

The answer to this question will not be too complicated. The fact is that drilling a wall of concrete, as mentioned above, is an extremely difficult process. To solve this issue, one of two types of tools should be used: either a hammer drill or a drill.

Both will be good in certain conditions. I will explain why. The best thing, of course, is to use a hammer drill: it is designed specifically for concrete walls and it is common practice to use it. After all, a punch easily pierces both stone and concrete surfaces. Another of its advantages is the ability to drill large diameter holes, which a drill cannot do.

But, if you have a wall of foam concrete in front of you, or if you need to drill several small holes - a drill is quite suitable. In this case, the punch can split the surface of the wall, which is not very successful. But, as already mentioned, do not count on large holes, only with a diameter of no more than 12-15 cm. In addition, drilling a concrete wall has its own nuances, which we will consider below.


How to drill a concrete wall with a conventional drill?

Let's talk a bit about drilling with a conventional drill. So, let's start with the fact that the usual here is hardly suitable. Those. theoretically, of course, this is possible. But in practice it is extremely difficult. Mandatory in this case, the use of a special drill bit for concrete work with a tip coated with a composition of hard alloys.

The best way would be to use a special impact drill. How is it different from usual? By the fact that in such a drill, drill movements are carried out due to special ratchets with teeth interacting with each other. It is not difficult to use such a drill to carry out high-quality work. To do this, simply transfer the drill from the normal rotational mode to the shock rotation mode.


But no matter what type of drill you use, how much the use of specialized nozzles is relevant. Nozzles (crowns) are sold in two configurations: for hammer or hammerless drilling.

The nozzle classification is as follows:

Toothed crowns for drilling with impact function.  A concrete wall can be drilled with such crowns with a cutting edge from separately soldered teeth made of strong alloys. For quick-clamping chucks, drills are available on such SDS tails. Their strength is so high that it is possible to cut metal, only the impact mode contributes to their destruction, creating unacceptable loads. That is why such drills are used to drill a hole between the reinforcement of reinforced concrete slabs or brick walls.

Diamond crown for drilling shockless.  These are more modern nozzles that simplify the task several times better than usual. The abrasive edge with cuts on them is created by diamond spraying or by spraying corundum sand. As you know, diamond is distinguished by its unprecedented strength. That is why he easily copes with concrete wall reinforcement. Such a nozzle can make a hole at least 1.5 meters deep and more than half a meter in diameter. This type of nozzles is already used by professionals, but nozzles with a diameter of up to 100 mm can very well be used in domestic conditions.

KS standard crowns.  Crowns with diamond crystals embedded on the cutting edge. You can use them for slabs, rocky soils, monolithic concrete structures  from high strength brands. It can easily replace hard carbide toothed crowns.

Based on your conditions, you can safely choose the necessary drill for a drill and drill a hole. But there are also a number of recommendations for working with a conventional drill, which is not equipped with a shock function.

To do this, you start drilling a wall, but are interrupted periodically. It is necessary to drive a pointed drill into the concrete surface with your hands and destroy the concrete with metal punches. We take our drill or chisel, other fixtures of the appropriate and required diameter metal and hit them with a hammer / sledgehammer. Rotate the punch periodically. Then take the drill again.

Note that when drilling a hole in a concrete wall with a conventional drill, you risk breaking the tool. Necessarily a low-power drill must be given rest. Drills also have the ability to heat, so you need to cool them with water. At the same time, take a break every 10-15 minutes of work, leaving the same amount of time for a break for the instrument.
