Technology of drilling holes in concrete with their own hands

Many years of practice shows that drilling holes in concrete is a serious task.

This task has to be solved by the owners of apartments when settling in a new house, in a habitable room during repairs and other everyday situations.

Many craftsmen prefer to do it themselves.

Despite the fact that concrete is considered the most durable building material, it is necessary to drill it often.

For these purposes, there is a special tool and equipment.

Drilling technology is inherently simple, but it requires the artist to have the skills to handle the instrument and average physical training.

Why do holes?

Multi-storey houses made of reinforced concrete panels are erected quickly, in the shortest possible time. The overwhelming majority of the urban population lives in these houses.

Any desire to create a comfortable environment in an apartment is accompanied by drilling of concrete walls.

Concrete drilling is necessary in the following cases:

  • installation of plumbing fixtures;
  • apartment repair;
  • furniture installation;
  • installation of additional wiring.

Each of these situations has its own peculiarities. For podrozetnikov require wide openings, for the hanging of the cupboard - narrow and deep.

The strength of concrete, its high reliability create serious difficulties for the realization of the conceived projects.

In order to drill a small hole and fix the shelf under the dishes in this place, you have to invite specialists or "hollow" the wall with your own hands.

More often holes are pierced by a perforator or a drill with a hammer.

If large-scale repairs are carried out, then you must find and use special equipment that is used in drilling concrete.

To work of this kind were performed qualitatively, without additional costs and fuss, you need to properly prepare for them.

The preparation is to determine where the holes in the concrete will drill and at what depth. Particular attention should be paid to the drilling holes for podrozetnikov in concrete.

The work in this case is carried out in close proximity to the electrical wiring. To comply with safety regulations, you must always disconnect this section.

This can be difficult. If you disconnect the entire apartment, then connect the instrument and equipment will have a temporary scheme.

You can independently connect to the power supply in the switchboard. But provided that the employee has an admission to work in electrical installations.

Tool selection

After the number of holes, their diameter and location are determined, you need to select the right tool for drilling concrete.

The exact choice depends on the quality of the hole and, ultimately, the reliability of attaching the object to the wall.

The most common tools for drilling holes with your own hands are the following tools:

  • drill;
  • perforator;
  • chisel and hammer;
  • drill bit with a winning tip;
  • drilling machine;
  • diamond or toothed crown.

With the help of cutting attachments, which are now on the market in large numbers, it is possible to drill holes of any depth and diameter in the concrete.

As a rule, such attachments are equipped with a machine for drilling holes of large diameter. Equipment of this type has a high cost.

Specialized companies that are engaged in repair on a professional basis can purchase the machine.

For an overwhelming number of masters who carry out repairs in the apartment with their own hands, such an installation is simply not needed.

If you need to do a small amount of work on a concrete surface, you can easily do with a drill, a perforator and even a screwdriver. Very often in such situations an impact drill is used.

If necessary, drill a hole of large diameter, the so-called crown is used. In appearance, this cutting tool is a hollow cylinder.

This form increases the drilling efficiency, because the cut concrete crumb is guided into this cylinder and does not prevent the tool from moving inward.

It is convenient to use a crown of the appropriate diameter to drill the jigs.

Such crowns are equipped with equipment for drilling concrete walls during major repairs and re-planning of living quarters.

When working with a manual perforator, it is recommended to use crown teeth made of hard metal alloys. This cutting tool has a high wear resistance.

A diamond-coated crown is used when drilling is performed in a non-impact way. In this case, the working surface of the crown should be periodically cooled in water.

Punch and drill are the most common equipment used for drilling concrete. They easily "cope" with drilling holes up to 100 mm in diameter.

For larger hole sizes, it is advisable to use a machine that is attached to the wall using anchors. The installation of such equipment requires a professional approach.

Drilling process

In order for the hole drilling work to be carried out in a short time and with the proper quality, it is necessary to strictly follow the current rules.

The tool to be used must be in good condition and at hand.

Techniques for working with a puncher and a drill are the same.

Layout of

The first step is to determine the places in which the electrical wiring is laid.

This can be done by focusing on the location of the podzroetnikov. Then points are marked in which it is necessary to drill holes.

Labels are applied with a standard drill bit.

This is to ensure that the direction of the tool when drilling concrete is exactly perpendicular.

Drilling

It is very important that the initial setting of the cutting element is correct, neither at random nor at random.

When drilling every 2-3 cm, you need to perform a return movement with a drill, without turning it off.

This is required in order for crumbs and dust to spill out of the hole.

Important point - after 5-7 minutes of operation it is necessary to cool the cutting tool by dipping into a vessel with water.

Overcoming obstacles

Very often when drilling concrete walls with your own hands, a drill or drill rests against metal reinforcement. At this moment, the usual sound of a working drill turns into a squeal.

You must immediately stop working. This obstacle is overcome by a punch or a drill, which is designed to work with metal.

Installation of this drill takes a little time and drilling can be continued.

Drilling with diamond bits

To date, diamond drilling holes in concrete is considered the most effective way. The machine for performing the work can have a different design.

Its transportation and installation in the workplace is performed promptly and does not require special devices or conditions.

One of the features that this equipment possesses is that drilling can be performed in different planes and directions. The depth of the hole can be up to two meters.

The diameter is up to 50 cm. The drilling unit is mounted on a special frame, which provides a secure fixation in the desired position.

The undoubted advantage of this drilling method is that the installation of podzroetnikov and other electrical appliances can be performed immediately after the completion of work, using only a screwdriver and a screwdriver.

There is very little dust and dirt after drilling. The main drawback is that the equipment for diamond drilling has a high cost.

Buy this machine for home affairs is unrealistic. Practice shows that you should not do this. In the house it is enough to have an impact drill and a set of drills.

This kit can do without any need.

Safety precautions

When drilling concrete walls using a drill or perforator, basic safety rules must be observed.

The first is to have safety goggles. The second is to wear a respirator so as not to inhale dust.

You need to work with gloves.

During drilling, when the drill is immersed in water, do not allow liquid to drill on the drill or perforator. Moisture can disable it.
