How To Properly Drill A Concrete Wall With A Hammer Drill

How to drill a concrete wall correctly Many craftsmen and those who are going to carry out repairs on their own want to know how to drill a concrete wall with an ordinary drill, and whether it is possible at all.

How to properly drill a concrete wall

The process of repairing an apartment includes many works related to the creation of holes in the walls: for this, tools of various designs and capacities can be used. Many craftsmen and those who are going to carry out repairs on their own want to know how to drill a concrete wall with an ordinary drill, and if this is possible at all. For such work, a puncher is usually used, but it is not always suitable for this, besides, if the tool is to be bought, then its cost is much higher than that of a drill.

Features of the choice of tool

In most cases, it is better to use a perforator for drilling concrete: it has increased power, is designed for punching hard surfaces, and allows you to make holes large in diameter. The use of the tool is impractical in the following cases:

  • The need to drill the wall to a depth of 10-12 mm;
  • Work with foam concrete, which crumbles when processed with a perforator;
  • In work it is required to make no more than 10-15 holes.

Before drilling a wall, it is important to choose the drill itself: it should not be hammerless, since this type is ineffective when drilling concrete, the nozzle and cartridge become unusable almost immediately. The nozzles themselves must be victorious, intended for concrete work, the tip with a carbide coating.

In some cases, a good solution would be to purchase a perforator drill: the device is more expensive than the classic model, but it has a higher power that can be adjusted.

Which attachments to choose?

Before drilling a hole in a concrete wall, you need to select a nozzle of the appropriate design. The following varieties are used for work:

  1. Impact-type serrated crowns for drilling. When working with concrete, it is recommended to use a variety of separate soldering teeth, made from the most durable metal alloys. Many bits are equipped with SDS shanks for installation in keyless drills. The drills are well suited for concrete walls, however, when in contact with metal, they can begin to collapse, therefore, before drilling a reinforced concrete wall, you need to check that there is no reinforcement in the place of work.
  2. Diamond core bits designed for hammerless drilling of holes. Such nozzles are more modern, with their help it is easier to make a hole in a concrete wall. The edge of the crowns has an abrasive structure and special cutouts; during production, it is processed by spraying diamond chips or corundum. Before making a hole in the wall, you just need to select the desired length of the nozzle: in everyday life, varieties with a diameter of up to 100-120 mm are used, in professional work, larger crowns are used. A distinctive feature is the ability to drill without the risk of damaging the fixture with fittings.
  3. KS-bits, which have a cutting edge with crystalline diamond particles. These attachments are used for most solid walls, including drilling into concrete slabs, exterior walls and stone structures.

How to properly drill concrete with a drill?

Typically, such work is performed in the following cases:

  • Rough finishing of premises;
  • Installation of built-in furniture and appliances;
  • Installation of wiring and plumbing when communications are required to be concreted.

When using a victorious nozzle in the course of work, it is required from time to time to use a metal punch, which is selected to the size of the hole being formed. Such a tool allows the drill not to jam when the drill is deeply immersed: the punch is placed in concrete and deepened by hammer blows to make a hole in the wall, destroying the seal.

This process is quite long, an alternative can be the use of diamond bits: a drill equipped with such attachments will not get stuck in concrete.

Working with an impact drill with a diamond core bit

  1. Before drilling a hole in the wall, you need to install the desired nozzle, after making sure that the tool is in good working order and the drill is intact.
  2. It is required to drill the concrete carefully; when using low-power equipment, the duration of the continuous operation of the drill should not be more than 10-12 minutes. If the drilling is delayed, it is necessary to take breaks so that the motor of the device cools down.
  3. After drilling the concrete wall, it became clear, then in addition it is worth considering that for each new hole it is required to process the nozzle. You can moisten the surface with water to facilitate the procedure and save the metal from deformation.

Drills, drill bits, crowns for concrete

The choice of accessories is of great importance. The victorious tip is T-shaped. If you want to get a really durable tool, buy drills from domestic manufacturers, where the metal ratio is 9: 1, if you buy a Chinese-made drill, know that there are less hard alloys there.

Hardened drills have black tint, titanium coated drills have gold tint. Titanium is much stronger.

Drilling concrete with a drill

For a drill, choose drills with a shank in the form of a polyhedron or a cylinder, for a drill perforator with the marking SDS-plus, SDS-max. Drill bits and hammer drills are not interchangeable: they can be installed on another tool only with an adapter.

AugerDesigned for making deep passages. Their length can be up to 1 m.
GentleAllows quick creation of small diameter holes.
SpiralUsed for drilling large diameter passes.

But the fact is that with the help of drills, holes are made only up to 4 cm in diameter. To drill larger passages in concrete, use carbide-tipped concrete drill bits. Their diameter is 35-120 mm. However, the most common crowns are 68 mm in diameter. They are ideal for creating socket holes. Extension cords are commercially available that allow you to make holes deeper than 15 cm.

If a drill is used, then tungsten carbide-coated bits should be selected. The ability to work with such crowns is determined by the power of the drill. It must be over 1000 watts.

Walls and ceilings of modern buildings are most often made of monolithic reinforced concrete slabs. It is well known that concrete is a material of increased strength, the handling of which requires knowledge of its processing techniques. In particular, it is necessary to drill a concrete wall with a special tool: a drill or a hammer drill.

Perforator

When using a hammer drill or impact drill, they must be switched to impact mode, a working tool with a victorious tip is inserted and it must be directed perpendicular to the wall surface.

If it takes a long time to drill holes, periodically you need to wet the drill, so that it does not overheat too much.

After you have drilled to the required depth, it is necessary to pull the working tool back without turning off the punch. To clean the finished hole from dust, it is necessary to deepen and pull out the drill several times.

Diamond drilling

This is the most effective way by which you can easily and quickly make a hole of the required diameter in a concrete wall.

To carry out these works, you will need special equipment, consisting of the following elements:

  1. Electric motor;
  2. A stand that is securely fixed to the base;
  3. Drill bit.

It is not necessary 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.

As the price of such equipment is very high, then buying it for domestic use is impractical. If it is necessary to make a hole with a large diameter, you can always invite specialists for this.

The better to drill

As already mentioned, there are several ways to drill a concrete wall, we will consider each of them in more detail.

How to drill without dust: the options are better

Construction work is always accompanied by dust and debris, but using some guidelines and tips, it can be significantly reduced:

  • The hammer drill leaves little dust during operation so that it does not scatter around the room at the same time use a construction vacuum cleaner. Some brands of tools have a built-in vacuum cleaner, which makes the task easier;
  • Using a drill, it is best to either make a jig on the end or a bag, or make an envelope under the hole so that debris falls into it.

Drill

The tool is suitable when you need to make multiple holes. You can use a conventional drill. When immersing a victorious drill into the body of the wall, sometimes it is necessary to break the concrete with a punch that matches the diameter of the hole. This is necessary when the drill starts to get stuck in the surface, bumping into too dense areas. The process is quite laborious.

For greater efficiency, you can use universal drills that are diamond-coated. They are installed only on a conventional drill or on a tool where the vibration function is disabled.

For large-scale work, an impact drill and drills with victorious tips are used. They are designed for holes up to 12 mm. The drill is suitable for working with metal, concrete.

Tools for work

For work, they use different tools, the main ones: a drill, a perforator, a screwdriver. There are nuances when using each.
