How to properly drill a concrete wall: technology. Choosing a tool for work

Many people have probably faced the problem of making a hole in concrete. Of course, everything is easily solved with a puncher. Holes are drilled for them very quickly, but noisy. If we are going to do overhaul, then only a puncher will facilitate our work, speed up the process of performing work. Unfortunately, it is not present in every home. The high cost is to blame. In addition, for home use, it is rarely needed. But almost everyone has a drill. It is more versatile at its low cost. The drill can drill holes, tighten screws and much more. Unfortunately, when it comes time to drill holes in concrete, most hardware store sellers offer winded drills.

I used to buy these drills myself. I tried to drill holes in concrete in different modes (with impact rotation, without it). Drilled holes with a special construction, very powerful drill the size of a perforator. It turned out a little easier, a little faster. I tried to sharpen the victorious soldering. It brought results, but not for long. The drill quickly sat down. I once had to drill a hole in a tile. A tiler I know recommended a special diamond drill bit.

It is also called a feather. Diamond drills are designed for hammerless drilling. They can drill a small number of holes, after which the diamond coating is erased, the drill becomes unusable. Cheap drills are enough for 10 - 15 holes. Expensive up to about fifty. Do not overheat diamond drills. 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 drill, no chips are formed. I decided to drill a hole in the concrete. The result pleased me. The hole was made quickly, without any effort, the main thing is noiseless. I also cooled the drill. The diamond drills are short, but this is enough to hang a baguette, chandelier, TV, any furniture ... Now I am sure that I will never cause inconvenience to my neighbors.

How to drill a hole in a wall

It would seem that what could be easier than drilling holes in the walls. However, if you look at the issue more broadly, it turns out to be multifaceted and very extensive. Firstly, what size the hole should be, secondly, what material the wall itself is made of, thirdly, with what tool you are going to do it, and so on. Today we will talk with you on the topic, how to drill a hole in the wall... We will share interesting information that can be useful both during repairs and just in everyday life.

Work in protective clothing

1. Performing any installation work especially with a power tool, always wear at least gloves.
2. In order not to breathe the dust thrown into the air, it is worth wearing at least a simple medical mask for 2 rubles. A hat will also do the trick, especially if you drill at a height and debris may fall on your head.
3. Hold the tool firmly and level while drilling. There are times when the drill wedges in the hole, and the hammer drill can pull out of the hands, which is fraught with injuries. The drill should enter the wall only perpendicular to it (unless special devices are used), any distortions can lead to the fact that part of the wall will crumble.
4. It is very convenient when an additional handle is installed at the hammer drill or drill - this way the tool is easier and more reliable to hold.

Perforators

The mode of operation for the tool is selected depending on the type of surface you are dealing with. The size of the drills or crowns is selected according to the size of the anchors and other equipment that will be installed in the hole.

The basic principle used when drilling is the material with which you do it, must be stronger than the wall material, that is, you cannot drill concrete with a drill for wood, which does not have any additional spraying, so it is so important to choose the right tool.

Concrete drilling - simple and professional

Professional machine for drilling large holes in thick walls

So, we may need holes in the walls for different purposes, respectively, its diameter and depth will depend on this. The photo above shows how a special water-cooled installation is biting into the concrete with a powerful crown - such large holes are needed for the installation of communication lines, ventilation, sewage and other things. The need for tools that can cope with such a task in Lately has increased many times, since now almost everything is being built using monolith technology. For brick walls this is also sometimes required, for example, the builders did not provide for an exhaust hood, or you need to make a neat conclusion from the boiler.

Drilling through a brick wall

This approach allows you to cope with the task in the shortest possible time, plus the strength of the wall is not violated. Only a few can afford such equipment, and there is no point in buying it. Only specialized organizations are engaged in professional drilling. We will not describe the process of diamond drilling in detail, but we will go through the main points in order to expand the general horizons.

Table 1. Instructions for drilling concrete.

Steps, images:	Description
Step 1. Drilling a hole for the bed. We drill holes for the bed	Good equipment has a bed on which the cutting bit moves in the right direction. In order to secure the frame to the wall with high quality, you will need to make a hole in it strictly perpendicular to it.
Step 2. Fixing the bed. We fix the bed	We fix the bed with a powerful metal anchor. The tool is now ready for use.
Step 3. Setting up the machine. Setting up the car	Then the operator sets the value of the rotation speed and axial load. It is very important to select the correct settings for a specific material, otherwise the drilling process may take several hours and the hole will not be smooth.
Step 4. Drilling.	We start drilling and do this until the crown goes through the entire wall. As a result, we get a perfectly flat hole, minimum of dirt and dust

Interesting to know! The cutting tool must be constantly cooled. If the hole is large, and the wall is thick, organize the water supply through special hoses. This measure allows for less dusting.

Now, from professional tools, let's move on to more mundane ones, to those that we constantly encounter in practice. Concrete - very hard material... In addition, reinforcing rods made of steel or fiberglass can pass inside it. A tool with a percussion function can cope with its drilling - the impulse from the drill will more effectively destroy the material. It is not worth using a simple electric drill. No, you will make a hole, but you will spend not 10 seconds on it, but about 10 minutes. Agree, the difference is enormous.

Interesting to know! If the hole diameter is less than or equal to 13 mm, then an impact drill is enough for work. Large ones are made only with a puncher.

A screwdriver can only handle lightweight concrete, and even then not everyone

Concrete walls also include lightweight concrete - foam blocks, gas blocks. These materials are not very dense, so even a screwdriver may be enough for work if it has a resourceful and powerful electric motor.

Following important point Is the selection of the drill. Concrete and other hard materials, such as brick, can only be drilled with solid carbide tools - victorious drills. A very durable one will win, the tip of the drill is made from it, after grinding which, the device becomes unusable.

The drill bit is victorious

Advice! If you try to use these drills on wood, you will end up with ugly ragged holes. Wood is too soft for him.

Having prepared everything you need, you can start work:

Step 1. First, we need to do some preparation. The main problem may be the presence at the drilling site electrical wiring or pipes for water supply and heating... To avoid accidents, you need to make sure that you do not fall into them. A metal detector or a special device that reacts only to wiring can help in this matter. Pipes inside the walls, if they are made of polypropylene and other polymers, the metal detector will find only if they have metal reinforcement. Otherwise, you need to look at the drawings or photographs of the communication lines.

Wall metal detector

Step 2. Before drilling, you need to outline the entry point of the drill, for this you can use a pencil, marker or center punch, if you need not only marking, but also a pothole so that the drill does not slip. Usually, when you start drilling concrete or brick, the drill does not go too far to the side, but it can still lead, and the hole will shift a little. In some situations this is uncritical, but in others, on the contrary, it is unacceptable, for example, you need to screw on the bracket, which has a strict arrangement of the holes for the anchor.

Center punch of different sizes

If the surface of the wall is finished with ceramic tiles, then it is even more difficult to start drilling without a center punch, especially if this tile is glossy - the drill will slide on it even more, leaving scratches. If you do not have such a device at hand, then you can replace it classic dowel hammer, or start drilling at the lowest RPM, and only after making sure that the drill is going as it should, accelerate the tool.

Step 3. Small holes are used mainly for plastic dowels and metal anchors - in the first case, it is recommended to make a hole slightly deeper than the length of the element, literally 3-5 mm. If this is not foreseen, it may not go to the end, it will remain protruding above the plane of the wall, or even break. This feature is typical for dowels due to their shape.

This is what a depth gauge looks like

Step 4. There are walls that are very thick, and the depth of the hole will not play a special role for them, especially if the dowel has a stopper cap that will prevent it from slipping inside. And there are thin partitions, where busting is fraught with damage to the finish on the other hand, plaster falling off, and so on. In this case, it is necessary accurately determine the depth of the drill... For this, limiters in the form of rods are used, fixed in a special device on the additional handle of the perforator. Reliable and accurate, but not always.

There are such models of the tool in which the fixation of the limiting rod is poorly thought out. It can slip through the hole, making it risky and inconvenient to use. In such a case, you can use folk method drilling depth designation.

Homemade electrical tape limiter

Take a piece of electrical tape and wrap it at the right level directly onto the drill. If you need to make many of the same holes, then make sure that the edges of such a mark are not crushed, since after several entries of the drill into the concrete, it can give an error. You can also make a mark on the drill with a marker, but it will not last very long either, since it will quickly erase and become unobtrusive, especially in the debris that comes out of the hole.

Step 5. When drilling concrete, a lot of drilling waste is emitted, or in a simple way - dust. When you work in a newly built house, this does not create any interference, but if the premises are already residential, everything is equipped with furniture, and you don’t want to dirty anything, it becomes more difficult to drill a hole in the wall. But we would not be us if we did not come up with ways to deal with such a trifling problem:

• The photo below shows a rotary hammer equipped with a vacuum cleaner and a dust bag. It is a pleasure to work with such a tool - with good suction power, practically no debris will get into the room. It is especially convenient to use it at height.

Rotary hammer with vacuum cleaner

• Such equipment costs a lot of money, so less drastic measures can be taken. For example, use a home vacuum cleaner. It doesn't need to be tied to a hammer drill - just have someone hold the tube under the hole while you drill it. The effect will not be worse.
• In some situations, dust collectors, which come in the form of plastic or rubber bowls, help. It is convenient to work with these devices when drilling the ceiling, but they are not so well suited for walls, since when removing the drill, debris can spill out.

Dust collector tool

• The easiest method is to use a damp cloth. While you are drilling, the assistant holds it underneath and then gently removes it. The remaining particles of debris on the wall are wiped off with a clean cloth.
• If there is absolutely no one to help you, then you can make such a waste bin, as shown in the photo below. To do this, you will need an old newspaper and masking tape, which, when peeled off, will not leave marks on the wall. It is glued just below the drilling point, and all the waste will fall inward.

Garbage bin from old newspaper

If all the dusty work has been completed and you need to prepare the wall for painting, then it will be very useful for the reader. In this material, we will consider in detail the main types of putties, tools that will be needed in the process. As well as step-by-step instruction applying putty on the wall.

How to properly drill ceramic tiles and porcelain stoneware

Perfectly smooth hole in ceramic tiles

If you have ceramic tiles glued to your wall, then the drilling process will become somewhat more complicated, and will consist of two stages. Let's describe them in order.

First you need to prepare all the tools: masking tape, pencil, marker, diamond crown, feather drill, as shown in the photo above, and an electric drill. Ceramic tiles are very durable material, but at the same time it is fragile... If she gets hit, she breaks apart, so drilling it with a blow is prohibited... However, drilling it is very easy and without this function - quite high revolutions and a special drill.

Table 2. Drilling instructions ceramic tiles.

Steps, photo:	Description:
Step 1. Tile markup. We mark	The first step is precise markup. It can be done with a marker, but in the heat of work, the cap from it is constantly lost, which is why it soon dries up and stops writing. Also, its tip is disheveled, which will interfere with putting accurate marks. In some situations, a pencil helps out, but it writes poorly on glossy tiles, and it is practically invisible. Masking tape will help out in such a situation. We glue it on the intended place of drilling and make a drawing of any complexity. In addition, this method allows you to add a small comment to the markup, if necessary.
Step 2. Drilling.	Clamp the feather drill in the chuck. It is very convenient to use a second tool for this, in addition to the punch. A screwdriver will be enough. Interesting to know! Masking tape not only allows you to make accurate markings, but also to drill the first millimeters of the tile surface with high precision - the drill will not slip on the glossy surface. We start drilling at low speeds, and as soon as we understand that the drill has started to enter, we squeeze the maximum out of the tool. If you feel the drill has sunk under the tiles and touches the concrete, stop working and remove the tool.
Step 3. We drill concrete.	You cannot continue to work with a feather drill, as it will become dull very quickly. To go deep into concrete or brick, we will need a hammer drill again. Since the tile has already been drilled, we cannot damage it with a blow of the tool, the only thing is that small chips may form along the edges of the hole. We go deeper into the wall to the desired level and the hole is ready.

The larger the hole, the harder it is to drill.

When you need to make holes in the tile, and in the concrete itself, holes for the sockets, diamond-coated crowns are used. They do their job well, but there is one important rule that must always be followed, namely - cool the cutting edge in time... If the tool is allowed to overheat, it can burn out and lose all its properties, therefore, with some frequency, work should be suspended and immersed in a container of cold water.

Drill cooling during tile drilling

Also, the water supply can be organized directly to the drilling site - for this you need a special water pump or an assistant who will add it as needed.

Very often the tool you need is not at hand. In such situations, alternative devices or original folk methods can help out.

• If you don't have kerner, which is just desperately needed when drilling porcelain stoneware, for example, it can be replaced with such guide plates as in the photo. You can buy them from the store, or make your own from a piece of plywood or similar material. You just need to hold such an overlay with your hand so that the crown cannot move anywhere. As soon as we let's go through the first millimeters, it can be removed to the side.

Crown guide

Homemade plywood counterpart

• There are situations when you need to drill a tile at an angle of 45 degrees... How is this even possible to do without damaging the surface? For this, special guiding devices are sold. The principle of its operation is as follows - first a perpendicular hole is made in the usual way, then the emphasis is immersed in it, after which the drill is transferred to the inclined guide... Naturally, different guides are used for drills of different diameters.

A set for drilling porcelain stoneware with crowns is needed for smaller holes

• What to do if you need to drill a hole for an outlet, and apart from the drill, there was nothing at hand. It's okay, the work can be done by him. To do this, on the wall you need make precise marking of the contours of the hole... After that, you need the whole circle drill with a minimum pitch as shown in the photo below. Further inner part knocked out with a spatula with a perforator or chisel and hammer.

Drilling holes large diameter without crown

• If while drilling you bump into metal, then it will not work to take it with a drill on concrete. Here you need to act differently - either we move the hole a little to the side, or we overcome the obstacle with the necessary drill, we cut it off with an engraver, a grinder, and so on.

An annoying nuisance

• Take a look at the photo below and appreciate the way the master came up with. He simply assembled a corner from the Lego constructor, put it in the right place, pressed it down and did exactly all the work. We develop the idea - so that such a device does not slide on glossy ceramics, you can stuff plasticine or mastic inside, for example.

People's resourcefulness knows no bounds

• From homemade products back to professional equipment. It is very convenient to use the suction cups. They are reliably fixed on ceramics, but only with a flat surface, so it will not work to call such a device universal. The photo shows a model with adjustable indentation.

Today we talked about drilling solid walls, but they can be made of wood, or from drywall and other materials. Unfortunately, there is no time for these topics now, but the principle of work will be similar. At the same time, drilling such bases is much easier, it is enough to use a tool for cutting wood.

Sooner or later, most people living in houses with concrete walls need to hang a cabinet, lamp, shelf or painting. At this point, the pressing question arises of how to drill a concrete wall. It's no secret that everyone House master at least once in my life I came across this problem, but not everyone knows how to solve it. Many courageously torture the drill and own strength, but, without achieving the desired result, they throw everything until the next attempt to make a hole in the wall. But the drill eventually breaks, and the shelves remain standing somewhere in the corner of the room or gathering dust in the closet. But there are still options - you just need to know and be able to use them.

Concrete structures are strong enough and difficult to drill. In addition, drills quite often come across crushed stone, which is part of concrete mix, from which the wall and ceiling slabs are molded.

Holes in concrete have to be made quite often, especially in the process:

• finishing works;
• furniture installation;
• air conditioner suspension;
• additional electrical wiring device;
• installation of plumbing.

There are two ways to solve the problem of holes in a concrete wall:

• hammer drill, and better with a puncher, with a victorious drill;
• diamond drilling.

It is worth noting that it is not possible to make a hole in a concrete wall with ordinary drills, therefore, before starting work, it is necessary to purchase drills with specially soldered plates made of high-strength victory alloy, which perfectly cope with concrete and brick. But for soft materials, it is not recommended to use them, since victorious drills do not cut them, but crumble them.

What will help a home craftsman?

In domestic conditions, when it is necessary to make 2-3 holes in concrete, you can do without conventional drill, without shock function. To do this, it is necessary, as the victorious drill is immersed in the body of the wall, from time to time to break the concrete with a strong metal pin (punch), which coincides in size with the diameter of the hole. It is used when the drill starts to "get stuck" in the wall. At this moment, a steel punch is inserted into the hole and they begin to beat it with a hammer or a sledgehammer, trying to crush too dense areas and punch the hole deeper. In this case, the pin is slightly turned. Then the hammerless drill can again come into operation.

All of the above steps are repeated one after another until the hole is increased to the required depth. This method is quite laborious and tedious, but quite acceptable for a pair of holes.

Alternatively, when drilling a hole in concrete, you can use universal diamond-coated drills. They are highly effective when working with metal, gravel and concrete. They can only be installed on a conventional electric drill, or on a tool with the vibration function disabled.

You need to work with the drill very carefully, otherwise it will fail too quickly. The advice given by professionals is that to avoid overheating the drill, it should be moistened with cold water from time to time.

How to decide on a tool?

For a larger volume of work, a hammer drill or drill with an impact function and drills with victorious tips are needed. An impact drill combines a rotary motion with a reciprocating motion, which helps it perfectly copes with light concrete, and when asked how to drill a concrete wall, which is a load-bearing one, there is a simple answer - a perforator will be the best assistant, the main purpose of which is to punch concrete fences. There is one more difference:

• the hammer drill is designed for drilling holes no more than 12 mm in diameter;
• the hammer drill is capable of drilling large holes.

The reinforcement trapped in the body of the concrete wall should be drilled with metal drills.

How are large holes drilled?

Professionals who are constantly faced with the problem of drilling holes in concrete use special equipment, which includes:

• powerful electric motor;
• drilling drive;
• diamond drill bits of different diameters;
• a guide post fixed on the base.

Diamond drilling allows you to make holes of large diameter - up to 40 cm. The process is fast enough, efficient, without unnecessary dust and noise. Water is automatically supplied to the drilling site, which simultaneously cools the diamond core bit and flushes away the dust.

Drilling with a hammer drill in stone or hard concrete is a rather laborious process. In especially difficult cases, when it is necessary to make a hole in a load-bearing wall or ceiling, it is still better to use a hammer drill (switching it to hammer drill mode). You should not even try to work with a drill when you need to drill holes for fixing the profiles on the concrete floor (during installation false ceiling). You will only waste time and be exhausted.

What are the drill bits for concrete

For work, use drills for concrete and drill bits (drills). The drill for concrete has a standard shank (like conventional drills for metal or wood) and is designed for an impact drill. For rotary hammers, drill bits are intended, which have shanks for SDS-design chucks with a diameter of 10 mm or 18 mm.

A concrete drill is made from a special hard alloy, in addition, it has a soldered tip (made of a superhard alloy based on titanium and tungsten). You can drill with such drills in concrete, brick, marble, stone, ceramics and other similar materials.

• It should be borne in mind that concrete drills should be used exclusively for working with concrete, ceramics, and stone. It is highly undesirable to drill metal or wood with them. If while drilling load-bearing wall the drill will rest against the steel reinforcement, it is better to drill it with a drill for metal, and then continue drilling with a drill in concrete.
• When working with an impact drill, sometimes hard stones can come across in concrete, which the drill does not always "take". In this case, use a special hammer or an old concrete drill and sledgehammer to manually crush the stone. Drilling can then be continued.

• When working with hard concrete, be sure to ensure that the drill does not overheat, allowing it to cool down every 10-15 minutes.
• Sometimes, when drilling a wall, pieces of plaster can fall off from its back side. To avoid this problem, it is enough to reduce the speed. Although the work will go a little slower, you will not have to worry about the safety of the wall.
• To drill ceramic tiles, use a drill for concrete, but set the mode of a conventional drill. In this case, you should not press hard so that the tile does not split.

A structure, the surface of which is far from easy to damage, as well as to drill. But if such a need nevertheless arose, then with the help of 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 using conventional methods. And everything lies in the structure of such a durable material:

As you can see, the action of all components is aimed at increasing the strength properties of the finished product. Particularly critical for conventional drills is crushed stone, which instantly blunts their cutting edges.

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

For example, if you need:

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

• Finish with plasterboard.

• Implementation of electrical wiring, installation of new sockets and switches... At the same time, for laying the wire, reinforced concrete is also cut with diamond circles.

• Plumbing connection.

Execution technology

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

Tool selection

First of all, let's decide how to drill a concrete wall. certainly not suitable.

You should choose from the following options:

• Drills with tacks from Pobedit... But it should be borne in mind that in this case, in addition to rotation, an impact function is also required.

Tip: Do not use a winder cutter for drilling iron or wood, as it will crush them.

• Diamond drills... Such edges will be able to cut stone even without hitting, 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 have nothing more suitable and you only need to make 2-3 holes. And in this case, from time to time, you will have 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 the blow in such a device is carried out due to the metal "ratchet", which is quickly erased under intense load.

• Perforator... It can handle large volumes and can even use special crown-shaped nozzles, 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, the better to drill concrete walls, the following generalized table will help:

Carrying out works

Now let's figure out how to drill a concrete wall. To do this, take a hammer drill as the clear winner of an impromptu competition.

The instruction for its operation is as follows:

1. Checking the shaft for debris. If one is found, delete it.
2. Insert the drill until it clicks. In this case, in some models it may be necessary to pull back the slider part of the "nose" of the tool.
3. We bring it strictly perpendicularly and start drilling, slightly pressing on it.

Tip: Moisten the drill bit with water from time to time. This will protect it from overheating and extend its service life.

1. The drill may get stuck during the drilling process. In this case, you should not try to loosen it in order to pull it out, as you can break off the tip. Just take the tool out of the apparatus, insert a smaller drill bit and try to use it to widen the hole and release the captured product.
2. Monitor the equipment while letting it cool down.

Output

We looked at how to drill a concrete wall, the process itself is not that difficult. The main thing is to choose the right tools and follow some rules while working. The most practical and rational decision will be the use of a hammer drill with victorious drills.

The video in this article will provide you with additional information regarding the presented materials for your consideration. Be careful and you will succeed!
