Quite often when repair work oh we have to drill a solid concrete base - be it holes for hanging shelf, place for socket or work on installing a new ceiling. And this task is quite difficult, as it might seem at first glance. Moreover, concrete is a very heterogeneous and extremely dense material.

Let's figure out how to drill concrete at home and what is the best way to do it.

How to drill into a concrete wall?

1. Ordinary drill bits are not suitable for concrete. It is better to use carbide drills, for example, pobedit. Such concrete drills have special soldered inserts made of carbide material at the ends (mainly a mixture of tungsten carbide and cobalt in a ratio of 10 to 90%). Carbide tips are easily recognizable - they have the shape of a kind of “house”.

2. If there are few holes planned and they are relatively narrow, then at home you can use a drill with

shock load function. An impact drill at home is suitable for holes in concrete with a diameter of no more than 12-13 mm, otherwise it is better to take a more expensive hammer drill. As for a conventional drill (“unstressed”), it is advisable to use it for concrete only as a last resort if you do not have other working tools at hand.

3. A hammer drill is suitable for any drilling in concrete - it is more effective due to its “crushing” function, although it is more expensive than an impact drill. In a hammer drill, the rotation of the drill is combined with its reciprocating motion, which makes drilling work much faster. A hammer drill is good when quite a lot of drilling work is expected (for example, when you need to attach lathing to a ceiling or walls). Keep in mind that a hammer drill is more powerful than a drill. Therefore, for example, for foam concrete ( cellular concrete) it is not suitable, as it will completely “destroy” the wall. Yes, even when drilling with a hammer drill ordinary concrete do not overdo it - make sure that the plaster does not crumble.

4. Special drills are used for the hammer drill (“SDS Plus” and “SDS-Max”) various diameters- from 4-5 mm to 7-8 cm. In order not to buy a very expensive complete set of drills, you need to choose drills for a hammer drill according to the diameter of the future dowel, and just in case, “plus or minus” a couple of neighboring ones in size.

5. In addition to drilling using an impact drill and hammer drill, there is another method - the so-called diamond drilling. Only this option requires special drilling rigs and diamond drills. This type of concrete drilling is very expensive, and, as a rule, a team of repairmen is hired to do it. Diamond drilling is used when a lot of repair work on drilling a concrete base is planned, or when large holes or longitudinal grooves (for example, when laying communications in a wall or floor). The advantage of this method is that after drilling rig no dust remains - it supplies water to the hole, washing away the dust and cooling the drill.

Stages of drilling concrete

1. Before starting work, be sure to think about whether there are any communications, cables, etc. in this place, so as not to damage anything.

3. The outer part of concrete is usually looser than the inner layers. Therefore, before you start drilling concrete, be sure to mark and widen the point of the future hole, that is, deepen (punch) the base of the drill entrance in this place. This is done to ensure that the drill does not slip or move to the side. For the core, you can use a hammer and a large sharp nail, a self-tapping screw or a special dowel.

4. During work, keep the working tool perpendicular to concrete base, otherwise the risk of the drill breaking will increase.

5. If you are drilling a hole impact drill, switch modes from time to time. In order to “beat” the surface, turn on the “impact” option in the drill.

6. Like a drill, like a drill (perforator), you need to give it a “rest” from time to time - about once every 10-15 minutes. pause work.

7. Another such moment - the same pobedit drills They do not like overheating, so under heavy operating load their tips must be periodically cooled with water.

8. To work on concrete, you will also need a triangular solid steel punch and a regular hammer - in case you encounter crushed stone in the concrete. By the way, an old Victory drill will also work as a punch. If reinforcement or stones (crushed stone) are encountered during the drilling process, they are removed separately. Reinforcement can be processed with conventional tools (a punch and a traditional metal drill), but stones only lend themselves well to a punch.

9. Suddenly you urgently need to make a couple of holes for a shelf, and only a regular drill is at hand (without impact mode), then during the drilling process, if necessary, you can periodically insert a punch into the hole and give it several blows with a hammer, and then turn it in the hole , then drill again with a drill, etc. Do not forget that the drill itself must be carbide.

10. Periodically remove cement chips and dust from the working hole - they interfere with drilling. They can be removed with a vacuum cleaner or a natural brush.

11. If the drill is stuck, do not loosen it, but carefully disconnect the tool, then put on a drill of a larger diameter and free the stuck tip, being careful not to touch it.

12. You need to drill holes in the concrete 1 cm longer than the length of the dowel, so that the latter will fit into the wall without any problems.

Good luck with your renovation!

When preparing to renovate your home, you need to be prepared for the fact that you will have to drill into the walls. For example, to secure a profile for drywall sheets. At this stage, some difficulties usually arise, since in many houses the walls are made of concrete. In addition to high strength, the material can be combined with reinforcement, which makes the work doubly difficult. To drill concrete wall using a regular drill, you need to familiarize yourself with all the nuances of the working process in advance.

Drilling load-bearing walls and partitions made of concrete is not an easy task. To complete the intended work quickly and efficiently, you need to know some secrets and tricks. It also doesn’t hurt to listen to opinions experienced craftsmen who advise:

How to choose a tool

Most often, a hammer drill is used to drill concrete. It has several advantages over a conventional drill.

These include:

Despite listed advantages, such a tool is not always suitable for the job. In some situations, its use is simply impractical.

A hammer drill is not suitable in the following cases:

• when shallow holes (10–12 mm) are needed in the wall;
• when working with foam blocks (otherwise the material will crumble);
• If required amount holes does not exceed 15 pieces.

Based on this, we can conclude that for home use A regular drill is more suitable. To purchase such a tool for drilling walls, you need to consider a number of important points.

The drill must meet the following requirements:

1. It should be impact, since this type is most effective when drilling concrete walls. In a hammerless drill, the attachments and chuck will fail too quickly.
2. It is better to buy pobedite attachments for it, intended for concrete work. And the tip is coated with durable alloys.

You can also choose a hammer drill. True, such a tool is more expensive regular model. But it has increased power, which can be adjusted at your discretion.

Which attachments are better?

To be able to drill into a concrete wall with a drill, you must first select the appropriate attachments. They must match the design exactly.

The following types are suitable for work:

Before using any attachments, you must check the wall for the presence of cables and wires, as well as fittings (if you have a metal detector). This will help protect the wall from major damage, and the tool from breakage.

First you need to prepare a drill, attachments and other related items. Then, while working, you won’t have to be distracted and waste time looking for the right things.

Drilling is often necessary in cases where:

• rough finishing;
• wiring;
• plumbing installation;
• concreting communications.

In this case, the concrete wall (if drilled correctly) should remain without severe damage and large chips.

When working with a drill with a pobedite bit, sometimes you need to use a metal punch. It is selected according to the size of the hole. This tool allows the drill not to jam when deepening the drill. To do this, the punch is driven into the concrete and driven with a hammer to split the solid obstacle into pieces. This process can take quite a long time, so it is better to use diamond crown. In addition, a drill with such an attachment will never get stuck in concrete.

Sequence of actions when drilling:

1. Carefully inspect the instruments. The drill must be in good condition, and the drill must be intact.
2. Begin to carefully drill a hole in the concrete with a drill, stopping continuous work instrument 10 minutes after the start of action.
3. The process can be continued only after the engine has cooled down.
4. Before drilling the next hole, it is necessary to moisten the nozzle with water. This will protect the metal from bending.

Such in simple ways You can drill through a concrete wall without a hammer drill.

Sometimes there are cases when the drill gets stuck in the wall. It is not advisable to use force in this case, otherwise it will break off and the edge of the nozzle will remain in the concrete. To free the drill, you must first disconnect it from the drill, then put on a bit of a smaller diameter and remove the stuck part.

To perform drilling yourself and at the same time avoid various injuries and unpleasant incidents, you need to follow safety precautions and follow the recommendations of specialists.

Many people have probably encountered the problem of making a hole in concrete. Of course, everything can be easily solved using a hammer drill. They drill holes very quickly, but are noisy. If we're going to do major renovation, then only a hammer drill will make our work easier and speed up the process of completing the work. But unfortunately, it is not present in every home. It's all to blame high price. In addition, it is rarely needed for home use. But almost everyone has a drill. It is more versatile at its low cost. A drill can be used to drill holes, tighten screws, and much more. Unfortunately, when it comes time to drill holes in concrete, most sellers construction stores

They offer drill bits with pobedite tip. I once bought these drills myself. Tried drilling holes in concrete different modes

(with impact rotation, without it). I drilled holes with a special construction, very powerful drill the size of a hammer drill. It turned out a little easier, a little faster. I tried to sharpen the pobedit soldering. This brought results, but not for long. The drill quickly sat down. One day I had to drill a hole in a tile. A tiler I know recommended a special diamond-coated drill to me.

It is also called a feather. Diamond coated drills are designed for hammerless drilling. They can drill a small number of holes, after which the diamond coating wears off and the drill becomes unusable. Cheap drills are enough for 10 - 15 holes. There are approximately up to fifty expensive ones. Diamond-coated drills must not be overheated. When drilling one hole, you will need to cool it with water 2 - 4 times. Otherwise, its service life will be sharply reduced. When drilling tiles with a diamond-coated drill, chips do not form. I decided to drill a hole in the concrete. The result pleased me. The hole was made quickly, without any effort, and most importantly, silently. I also cooled the drill. Diamond-coated drills are short in length, but this is quite enough to hang a baguette, a chandelier, a TV, any furniture... Now I am sure that I will never cause inconvenience to my neighbors.

Don’t despair or be upset if you didn’t manage to hang a shelf, lamp or cabinet right away, read our recommendations and everything will work out.

There are several options with which you can drill through a concrete wall yourself.

Concrete structures are highly durable, so drilling them yourself is quite difficult.

This is due to the fact that to create concrete products crushed stone is used and when you get on it while drilling, the process becomes very difficult.

The need to drill a concrete wall arises quite often; this is necessary for installing shelves, cabinets, air conditioning, mounting a lamp, or during or during the installation of beacons.

There are several ways to solve this problem:

• using a hammer drill or a powerful impact drill;
• an ordinary electric drill or screwdriver;
• diamond drilling.

To carry out this work, a regular drill is not suitable; it is necessary to purchase tools soldered with pobedite alloy.

It should be remembered that for walls made of relatively soft materials, you cannot use pobedite drills, as the holes will be uneven and the wall will collapse. It is also impossible to work with metal with such a tool.

To create holes large diameter or, diamond-coated annular drills are used. To use such a tool, it is necessary to use special installations; they allow you to make holes with a diameter of up to 250 mm.

Since the cost of such equipment is high, it is easier to hire specialists or you can rent it.

The better to drill

As already mentioned, there are several ways to drill through a concrete wall; let’s look at each of them in more detail.

Hammer

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

If drilling holes takes a long time, then The drill needs to be wetted periodically so that it does not overheat too much.

Once you have drilled to the required depth, you must pull the working tool back without turning off the hammer drill. To clean the finished hole from dust, you need to deepen and pull out the drill several times.

A regular drill or screwdriver

If you do not have the tools described above, then this work can be done using a conventional electric drill or a powerful screwdriver.

Drilling will take more time than using a hammer drill, but you can do it yourself.

In this case, in addition to the drill and drill bit, you will also need a punch. First, a small depression is made at the drilling site using a punch and a hammer.

After this, they insert the working tool into it and begin to drill. If the drill stops, break the hard areas again with a punch and continue working.

Although a regular electric drill or screwdriver is not suitable for working with concrete, if you don’t have a hammer drill, you can make several small holes with these tools, but you need to use a spear-shaped drill with a carbide tip, usually used for tiles.

Diamond drilling

This is the most effective method, with which you can simply and quickly make a hole of the required diameter in a concrete wall.

To perform the above work you will need special equipment, consisting of the following elements:

1. electric motor;
2. a stand that is securely fixed to the base;
3. core drill.

There is no need 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.

Because the price of such equipment is very high then buy it for household use inappropriate. If it is necessary to make a hole of a large diameter, you can always invite specialists for this.

In order for you to be able to drill through a concrete wall correctly, you must have necessary equipment, Perform all work carefully and adhere to the following recommendations:

• without a hammer drill, the work can be done with an impact drill or drilled with a screwdriver;
• do not buy cheap drills, as their pobedite tip falls off very quickly and they fail;
• instead of a punch, you can use a pobedit tool, with one you will break the crushed stone, and with the second, inserted into a regular electric drill, you will drill;
• to work with concrete, the hammer drill must have an SDS-plus chuck;
• take into account the placement of the fittings to determine where it is located, you can use a metal detector, if the fittings are exposed, it is necessary to prevent rusting;
• To work with concrete, you can use universal diamond-coated drills, but you need to insert them only into a regular drill, or you need to turn off the impact mode.

Conclusion

When performing the above work, you must adhere to the developed technologies and safety rules, then you can not only make the hole yourself without the involvement of expensive specialists, but also avoid injuries.

How to drill concrete? This question often arises among craftsmen during the construction and renovation of homes with. You have to drill into concrete to install electrical sockets and switches, lay pipes, wires and other communications.

When drilling concrete, a beginner faces a lot of problems, such as breaking the drill, or even the drill.

Concrete is very durable material. Drilling in the usual ways it lends itself very poorly. And if it is reinforced (reinforced concrete), this task becomes almost impossible with a conventional drill. How to drill into concrete? The problem of making holes in this material is becoming increasingly popular.

How to drill concrete?

Basic tools for drilling similar designs today are a drill equipped with an impact mechanism and a hammer drill. Correctly drill concrete with a hammer drill. It is designed for just such a thing. The holes made by a hammer drill can have enough big sizes both in their depth and in diameter. You can drill a wall using special working tools that have carbide coating or pobedite inserts. The most common ways to use this tool are:

The most powerful drilling tool concrete structures is a hammer drill.

• using a conventional tool with the additional use of a punch;
• use of a hammer drill or impact drill equipped with special tools;
• drilling with diamond tools.

Making a hole in a wall using the usual method is very difficult and takes a lot of time. The tool quickly becomes dull and fails. How to drill a wall correctly? The drilling point must constantly receive rotational and impact. Rotational movement is achieved using a drill, and impact is achieved using a punch and hammer. An old drill can be used as a punch. The hammer strikes its end. In this case, the concrete layer is partially destroyed. Destroyed particles are removed using a drill. The hole slowly but deepens. The most common method is to make holes with a hammer drill and a special cutting tool. The work goes quite quickly and efficiently. A small amount of work can be done with an impact drill with a carbide tool.

Diamond drilling is used for fairly large volumes of work. This method allows you to deal with the matter very quickly and without large quantity dust. How to get large diameter holes? This is done using diamond-coated crowns or carbide inserts. In some cases, special installations with a water vacuum cleaner are used. But usually a hammer drill can handle this task quite well. It is recommended to periodically remove the drill from the hole and moisten it with water.

Tools inserted into the drill chuck are usually available with a diameter of 4 mm. Largest diameter- 1.2 cm. Their length can be 40 cm. A plastic dowel is inserted into the finished hole, and a self-tapping screw is screwed into it. The diameter of the dowel must match the diameter of the hole. To hang cabinets and other pieces of furniture, it is recommended to drill holes and use dowels with a diameter of 8 mm.

Hammer drills

Drills used in a hammer drill are commonly called drills. Drills can have a diameter from 4 mm to 28 mm. Moreover, they have different lengths (diameter and length in millimeters):

• 4 — 50;
• 5 — 100;
• 6 — 150;
• 8 — 250;
• 10 — 540;
• 12 - more than 1000.

The hammer drill has an SDS-plus type shank. IN industrial installations Other shanks may be used. Making holes with a diameter of 35 mm is carried out with tools that are popularly called crowns. Their maximum diameter is 12 cm. Along the perimeter of the crown there are solderings made of pobedite or diamond coating. Crowns work without turning on the impact mechanism. The hole is drilled in several steps to cutting tool and the engine has cooled down. The drill bits drill well into tiles, so tiled concrete walls can be drilled without changing tools.

You can purchase special drills and bits at numerous tool and construction equipment stores.

Some tips:

1. Before mounting the tool in the chuck of a hammer drill or drill, it is necessary to clean it of dirt.
2. The drill shank must fit into the chuck until it stops.
3. For household drills and hammer drills, every 15 minutes of work you need to take a break for 10-15 minutes.
4. It is recommended to periodically moisten the drill with water.
5. Before making holes in the wall, you need to make sure that there are no pipes or electrical wiring in it.
6. You can use a metal detector to find pipes and wires in the wall.
7. You should start working with the switch off impact mechanism and at low speeds.
8. The depth of the hole should slightly exceed the length of the dowel that will be inserted into it.
9. The depth of the drill can be marked by wrapping a roll of electrical tape around the drill.
10. When working, it is recommended to use personal protective equipment.
11. It's better to buy drills famous manufacturers. An excellent choice are products from Bosch.
12. A diamond tool will help you quickly and efficiently drill many identical holes.
13. Drills and drill bits for concrete cannot be used when drilling metal and wood.

Drilling concrete walls is not a very simple task, but it is quite doable even at home.
