The renovation process in an apartment includes a lot of work related to creating holes in the walls: a tool can be used for this various designs and power. Many craftsmen and those who are planning to carry out repairs themselves want to know how to drill concrete wall with a regular drill and is it even possible? For such work, a hammer drill is usually used, but it is not always suitable for this; moreover, if you have to buy a tool, then its cost is much higher than that of a drill.
Features of choosing a tool
In most cases, it is better to use a hammer drill: it has increased power, is designed for punching hard surfaces, and allows you to make large-diameter holes. The use of the tool is inappropriate in the following cases:
- the need to drill the wall to a depth of 10-12 mm;
- working with, which crumbles when processed with a hammer drill;
- the work requires making no more than 10-15 holes.
Before drilling a wall, it is important to choose the drill itself: it should not be impactless, since this type is ineffective when drilling concrete; the attachment and chuck almost immediately become unusable. The nozzles themselves must be victorious, designed for concrete works, tip - with carbide coating.
In some cases a good decision will purchase a hammer drill: the device is more expensive classic model, but has increased power, which 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 types are used for work:
- Impact-type toothed bits designed for drilling. When working with concrete, it is recommended to use varieties made from individual soldering teeth, made from the most durable metal alloys. Many bits are equipped with SDS tails for installation in a drill with keyless chuck. Drills are well suited for concrete walls, however, upon contact with metal they can begin to collapse, so before drilling into a reinforced concrete wall, you need to check that there is no reinforcement used for reinforcement at the work site.
- Diamond bits, which are 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 only 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. Distinctive feature is the ability to drill without the risk of damaging the fixture with fittings.
- KS crowns that have cutting edge with crystalline diamond particles. Such nozzles are used for most solid walls, including drilling with them. concrete plates, external walls and stone structures.
Before drilling or partitioning, you need to make sure that wires or cables, if any, will not be touched during the work.
How to drill concrete with a drill?
Usually similar works are performed in the following cases:
- rough finishing of premises;
- installation of built-in furniture and appliances;
- installation of wiring and plumbing when communications need to be concreted.
When using a Pobedit nozzle during work, it is necessary from time to time to use a metal punch, which is selected to match the size of the hole being formed. This tool allows the drill not to jam when the drill is deeply immersed: the punch is placed in the concrete and deepened with hammer blows to make a hole in the wall, destroying the seal.
This process is quite long; an alternative is to use diamond bits: a drill equipped with such attachments will not get stuck in concrete.
Algorithm of actions:
- 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.
- Drilling concrete must be done carefully; when using low-power equipment, the duration of continuous operation of the drill should not be more than 10-12 minutes. If drilling takes a long time, you need to take breaks so that the device’s motor cools down.
- Once it has become clear to drill a concrete wall, it is also worth considering that for each new hole it is necessary to process the nozzle. You can moisten the surface with water to facilitate the procedure and protect the metal from deformation.
The whole process of work can be seen in the video:
If you encounter a stuck drill, do not remove it by force: this will lead to the device breaking off, resulting in the tip remaining in the concrete. You need to disconnect the nozzle, select a crown of reduced diameter and use it to pull out the stuck element.
Before deciding what to drill into concrete walls and starting work, you should pay attention to the following recommendations:
- if the hole diameter exceeds 12 mm and the depth is 10-11 cm, it is better to use a hammer drill or a hybrid device (drill-hammer);
- if holes are made for plastic dowels, the depth should be 7-10 mm greater than the size of the fastening element, since concrete dust and small particles of stone remain inside;
- It is recommended to start work at low speeds so that the nozzle does not move due to increased torque, and the impact mode is turned on when the drill passes 2-4 mm in depth;
- dust that appears during the drilling process can be removed with a vacuum cleaner; it is advisable to do this during the process, periodically stopping the drill and cleaning the hole from concrete particles;
- Be sure to follow safety precautions during work: you need to wear gloves to eliminate the risk of the handle slipping and safety glasses to prevent crumbs from getting into your eyes and damaging the mucous membranes.
In most cases, a concrete wall is drilled with a hammer drill, without a drill. If, as part of the repair, you need to make no more than 15-20 holes or the wall is made of foam concrete, using a drill is optimal choice which will save time and money.
Before punching a hole, you need to make sure that there is no wiring in this place, and check whether the attachment is suitable for such work (the duration and efficiency of the work depends on what kind of drill the drill is equipped with). When deciding how to drill a wall, you should pay attention to pobedite bits: with such a drill using a drill, you can easily make a hole up to 10-12 cm deep.
A hammer drill is intended for drilling concrete, but if one is not available, in many cases a hand-held electric drill will do the job. You can achieve success if you choose the right drill or crown. To figure out how to drill a concrete wall with a conventional drill, you need to know a clear algorithm of actions, take into account a number of important nuances drilling.
It is wise to start drilling concrete if the electric drill is equipped with a hammer function. Using a drill with a hammerless tool is pointless. The drill will simply overheat, which will result in the motor burning out. Using a non-impact tool, you can drill a large hole with a diamond core, if the power of the electric motor allows.
For simple hammer drilling of small holes, you will need an additional tool:
- A set of concrete drills of different diameters. They can be distinguished by special soldering on the carbide end. The element is a small plate with sharpened edges at an angle of 60 degrees. The screw part and cylindrical shank are made of ordinary tool steel.
- Punch. The tool is made in the form of a rod with a sharpened end. A punch helps to destroy concrete by hitting it with a hammer.
Concrete drills have one thing weakness. Upon contact with the fittings, the solder breaks off. If the immersion of the drill into the concrete has stopped and a characteristic whistle appears, the hole is tapped with a punch. If there is reinforcement, move the drilling site to the side.
When it is necessary to cut a large hole for a socket box with a drill, a crown is used instead of a drill. When choosing a nozzle, look at the shank. Its shape must be suitable for clamping in the chuck. The drill will fit a hex or SDS shank.
Drilling concrete is carried out by three types of crowns:
- Nozzles from carbide materials have a serrated cutting edge. Crowns are used only for impact drilling. If the drill does not have a hammer function, the soldering tips overheat and fall off the bowl. The crowns are afraid of contact with the reinforcement. To preserve the cutters, before drilling, try to drill through the wall with a drill. Additional action will help determine whether there is reinforcement in this area.
- Drilling a concrete wall with a hammerless drill is carried out with a diamond core bit. The nozzles are not afraid of contact with the fittings. Air-cooled crowns are produced for domestic use. They are recognized by the presence of holes on the cutting edge. Crowns for wet cutting Do not use with a drill. Diamond coating can be hard, soft or medium hard, which is reflected by the marking of the nozzle with the letters “T”, “M”, “C”. “KS” bits are usually used with a drill. The design of the nozzle provides slots for air cooling. The cutting edge is made of medium-hard diamond chips.
For drills, bits made of carbide materials are sold, where instead of soldering there is a coating of tungsten carbide chips. The nozzle can be used to carefully drill into a tiled wall. It is reasonable to use crowns if the drill power exceeds 1 kW.
Drilling a wall with a drill
The drilling process with a hammer drill requires maximum effort. It will take more time than when working with a hammer drill due to the lower power of the tool. Drills periodically give time to rest. The entire procedure for making a hole with a drill consists of the following steps:
- The location of the future hole is marked on the wall. Place a punch on the mark and hit it sharply 2-3 times with a hammer.
- After impacts, a small crater is formed in the concrete. A tapped drill is inserted into the recess, the hammer mode is turned on on the drill, and they begin to drill. When the hand feels overheating of the electric motor, the tool is given time to rest.
- The drill may stop going deep for two reasons: solid fractions of concrete or reinforcement have entered. Drilling is stopped. A punch is inserted inside the funnel and sharp blows are applied with a hammer. When the solid fractions are destroyed, continue drilling. If reinforcement gets in, it is better to move the hole to the side. If this option is not suitable, the rods can be cut with a diamond core bit or a metal drill.
Actions continue until the desired hole depth is reached.
The nuances of proper concrete drilling
In order for concrete drilling to be successful, a number of important nuances are taken into account:
- Making a hole with a diameter of more than 12 mm and a depth of 100 mm is best done with a hybrid power tool, a hammer drill.
- For plastic dowels, the depth of the hole is 7 mm greater than the length of the fastening element. The stock will become clogged with concrete dust when inserting the dowel.
- Work begins at medium speed of the drill without impact mode. The speed is increased when the drill reaches 4 mm deep. At the same time, the drummer mode is turned on. This measure is necessary to prevent the drill from moving along the wall due to strong vibrations.
- The drilling process is accompanied by a large amount of dust. If you turn on the vacuum cleaner, flying concrete particles will be immediately sucked up and will not clog the room.
- When clamping the drill in the chuck, check that the shank is inserted all the way.
- Operate with a low-power drill for a maximum of 15 minutes. 10 minutes is enough to rest. Before starting work, the drill is dipped in water. A little trick can reduce wear on the cutting tip.
- When doing through hole at high speeds, with reverse side a piece of concrete may break off the wall. Reducing the speed helps avoid damage.
If a drill is stuck in concrete, you should not try to remove it by hitting it with a hammer or loosening it with pliers. The shank will break off due to such actions, and the screw part will remain inside the wall. You can only remove a stuck element if you drill holes around it with a small-diameter drill.
Sometimes when doing finishing works there is a need to make a hole in the wall, for example, to secure metal profile when installing drywall. If the wall is concrete, then this procedure can cause certain difficulties, since this material has high strength, has a heterogeneous structure and contains metal fittings. Next we will look at how this problem can be solved.
Necessary tool
Due to the nature of concrete, drilling it will require special tool :
- (impact drill) – provides rotational and translational movement of the drill.
- Concrete drills For impact drill, made of hard alloys. Their shank and screw part are made of tool steel, and the cutting working area is a plate of carbide metal sharpened at 60 degrees, which is sealed into the groove of the cutting part of the tool.
- (needed when drilling with a conventional drill).
It must be said that it is possible to cope with the task with a tool without a striking function. Below we will take a closer look at how to drill through a concrete wall with a drill.
Drilling procedure with a hammer drill
The procedure for drilling a wall using a hammer drill and a special drill is quite simple:
- The concrete drill should be switched to hammer drilling mode and the operation should begin. The drill should be positioned strictly at an angle of 90 degrees with respect to the wall, unless drilling is specifically performed at a certain angle.
- After some time, the drill needs to be moistened in cold water and continue working.
- If the tool rests on something hard and stops going deeper, you will have to try to drill the wall in another place.
- Once the desired immersion depth has been reached, you should pull out the drill without turning off the drill. To clean the hole from dust, you need to deepen and pull out the drill several more times.
This completes the procedure.
Advice!
A hammer drill can be used for more than just drilling hard materials.
There are special attachments that turn this tool into a mixer.
Thanks to them, a drill-mixer for concrete does an excellent job of stirring the solution.
Drilling
Many home craftsmen doubt whether it is possible to drill concrete with a drill? Of course, this procedure will take much longer than when working with a hammer drill, however, it is quite possible to make a hole.
To perform this operation you will need a special punch. This tool is a rod with a pointed hard end. It is used to break up the surface in the drilling area.
Instructions for performing this work are as follows:
- First of all, you need to place a punch at the place where the future hole will be located and hit it several times with a hammer.
- Then, a drill is inserted into the resulting funnel and a hole is drilled. As when working with a hammer drill, you need to ensure that the tool does not overheat.
- If the drill stops going deep, you need to use the punch again - insert it into the hole and hit it hard with a hammer several times.
- Drilling is carried out in this way until the desired hole depth is reached.
Advice!
Often there is a need to cut concrete, in which case a grinder is used.
However, it should be borne in mind that reinforced concrete is cut with diamond wheels.
As a result, although a conventional drill is not suitable for concrete, in the absence of a hammer drill, it can also be used to drill a reinforced concrete wall.
In the photo - working with a punch
Advice!
A drill can be used not only to make holes, but also used for several other purposes.
For example, on our portal you can learn how to make a vibrator for concrete with your own hands from a drill.
This technology involves the use of special equipment, which is a set of the following elements:
- Electric motor;
- A stand that is fixed to the base;
- Core drills.
With this design, water is supplied directly to the drill to cool the tool. Therefore there is no need to interrupt the process. In addition, water washes away dust, so it does not have time to get into the surrounding space. Often, such an installation includes a water vacuum cleaner, which allows you to remove a mixture of water and dust from the surface.
Of course, it makes sense to use diamond drilling of holes in concrete only for industrial purposes, where it is necessary to perform a large number of holes, especially large diameter. The equipment is unlikely to be useful for domestic purposes.
In addition, the price of the kit, like any other professional tool, is quite high. Therefore, if you need, for example, to fix a shelf on the wall, it is more advisable to use a hammer drill. (See also article.)
Conclusion
With a reasonable approach, making a hole in concrete will not be difficult. The most important thing is to use the right equipment for this and follow a certain order actions. In addition, of course, it is necessary to follow safety precautions so that the work does not end in injury.
From the video in this article you can glean Additional information on this topic.
Concrete walls are the basis of many high and low-rise buildings. Every resident sooner or later has to hang something or attach something to the wall. A concrete drill is useful for attaching sconces, lamps, paintings, equipment, appliances, mirrors, etc. When using a conventional drill, it overheats, smoke appears, and after a few holes you have to change the attachment. Proper drilling will help complete the procedure quickly, and the tool will last for many cycles of use.
Choosing a tool and working with it
When choosing a method, it is worth choosing the right tool. A high-quality drill with an attachment will drill through a wall quickly and accurately. Not every tool is equally well suited for this purpose. A low quality concrete drill will require high costs time, or may not be able to cope with the task at all.
A high-quality drill with an attachment will drill through a wall quickly and accurately
When choosing a tool, pay attention to:
- presence of a rotation speed regulator. It is important to be able to adjust the speed for accurate drilling. Working exclusively at maximum speed will lead to drilling big hole and surface damage;
- ability to set the hammer drill mode. Useful for penetrating layers of higher density;
- drill installation depth adjustment;
- An auxiliary handle is included. Professional and powerful drill refers to heavy power tools, it is better to have a built-in handle for working with two hands;
- satisfactory power indicators to make it convenient to drill concrete, brick and other materials, because a drill is a universal tool.
Selecting a tool and working with a drill are important procedures, otherwise the wear of materials increases and the wall collapses. After selection best option drilling machine, it is important to decide which drill to use to drill a concrete wall. All stores offer nozzles with pobedit tips for stone; they are optimal for concrete.
Before starting work, it is better to get used to using the selected tool. It should be comfortable to use with one hand or two. One hand is placed on the handle, and the other is on the removable handle or on the side of the body.
Choosing a tool and working with a drill are important procedures It is important to always keep the drill strictly at right angles to the surface to prevent distortions and destruction of the coating.
Any device electric type vulnerable to temperature changes, before turning on it is recommended to wait until it warms up or cools down until room temperature. With sudden changes there is a risk of condensation. If there is no need for drilling temporarily, it is better to unplug the power tool.
When you need to drill a hole, you should first make sure that there is no wiring, built-in pipes or cables in the selected location. An easy way to detect such elements is to use a metal detector. There is almost always reinforcement in the wall; it is better to install a metal detector on non-ferrous metals (search for wiring) and then on steel. If you ignore the condition, there is a risk of bumping into the reinforcement, and the Victory drill will be hopelessly destroyed.
Initially, a point is marked on the wall. To prevent the tool from slipping, make the recess any strong metal object or a drill at low speed. After careful preparation, the concrete drill easily enters the wall. It is worth considering that a lining is applied on top of the cement - it is softer than the wall itself, which means that initially the drill goes easily, then it rests against durable material.
Preparing the surface for work
The type of material and holes determines which drill to use to drill a concrete wall. Right choice will increase the quality, accuracy of the result and the integrity of the nozzle. The assortment of stores has special drills for various types materials: wood, concrete, metal. The features of drills for concrete come down to the triangular shape of the tip and the application of a carbide composition to the tip. Regular drill With a pobedit drill, it is possible to crush concrete without tearing the material.
If the process stalls at the stage of drilling concrete, holes are drilled with a hammer drill or the impact mode is turned on. The only drawback of the hammer drill is the large holes, diameter 13 mm. Dense areas can be easily overcome with a mechanical punch and hammer. The area should be punched until the material softens. Then continue drilling the hole.
To drill several holes on concrete, special soldering tips are used on the nozzle:
- pobedite tip;
- universal drills, but they should be cooled regularly;
- Diamond drills for concrete are a relatively expensive material, but durable.
While drilling, make sure that there is no uncharacteristic sound of contact with metal. If you hit the reinforcement in the wall, it is important to complete the procedure while the nozzle is still sharp.
Choosing a drill bit for a drill Correctly drilling concrete with reinforcement can be done in 3 stages:
- Reach the metal layer with a pobedite tip.
- Install a drill for metal - the reinforcement is soft and should be drilled out easily.
- Continue working with the concrete drill.
A little about the structure of the drill and installation of the drill
Standard drill includes:
- cable from the network;
- power button;
- capacitor wires;
- reverse system;
- brushes with springs;
- anchor;
- stator;
- gearbox with chuck;
- bearings;
- keys;
- screws.
Impact drill device At correct installation drills increases the quality and safety of work. If you do not tighten the bit too much, there is a risk of the drill flying out and causing injury. It is recommended to immerse the nozzle all the way and clamp it with a special key.
Under no circumstances should you attempt to increase the length of the rod by partially inserting it into the chuck.
Before starting work, you should check for contamination on the drill. It is better to use rags to clean drills. The easiest way to drill through concrete is to press firmly on the handle in one go.
Selection of power for drills
When drilling concrete, it is best to use a device with a power of 600 W and 2500 rpm. To more accurately select the rotation speed, you should familiarize yourself with the recommendations of the drill manufacturer. To drill concrete, the crumbling method is used, which does not require high speeds.

Workers' comments helped identify actions that should be undone during the drilling process:
- Do not hold on to the rotating chuck during operation. There is a housing or handle for secure holding;
- If you work with gloves, you should use tight-fitting varieties. The protruding ends of the gloves may become twisted during rotation;
- pressing the drill with all your might is not The best decision, as the builder loses his balance and may fall. Another problem with excessive force is drill bit breakage;
- It is important to avoid placing human hands on the back side of the concrete, otherwise the drill will go through the wall and can cause serious injury.
- if the purpose of drilling is to install a plastic dowel, install a drill of a slightly larger diameter. Dust from drilling may prevent the dowel from going in completely;
- At the beginning of the procedure, the power tool is set to low speed, otherwise it is difficult to control the drill. After diving deep into the walls, they increase the speed or turn on the shock mode;
- during the drilling process, the drill should be moistened in cold water to protect it from overheating;
- if the drill bits are not held securely in the chuck or become loose during operation, it is replaced with a new one;
- It is recommended to wear special glasses that will protect against debris getting into your eyes.
We will offer information on related topics useful in construction:
- Dowels are not the only way to fix equipment and machinery to walls. will help you get the job done faster;
- When working with foam blocks and aerated concrete, you cannot use screws and dowels due to the low strength of the material. Anchors for aerated concrete - the most effective method fastenings;
- Most walls are based on reinforcement - it increases the durability of the structure, but requires great effort in the process of creating the frame. There are several ways to do this, but manual methods are difficult to do. will simplify the work, which is especially important in monolithic construction;
- to improve decorative qualities, impurities are added to the solution; there are even mixtures that can make;
- At the construction stage, it is worth thinking about the feasibility of cast structures. Various blocks will speed up the work process. will help you make the material yourself;
- If brick is chosen as the main material of the house, it is worth finding out what kind of mortar is needed for laying bricks.
Provided you follow all the rules for working with a drill and auger, follow the manufacturer's instructions and prepare well for drilling, you will be able to make a hole in a concrete wall without much difficulty.
How to drill a hole in a wall
It would seem that nothing could be simpler 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 should the hole be, secondly, what material is the wall itself made of, thirdly, what tool are you going to use to do this, and so on. Today we will talk to you about the topic, how to drill a hole in a wall. We will share interesting information, which can be useful both during repairs and just in everyday life.
Wear protective clothing
- Carrying out any installation work, especially with power tools, always wear at least gloves.
- To avoid breathing the dust thrown into the air, you should wear at least a simple medical mask for 2 rubles. A hat will also help, especially if you are drilling at height and debris may fall on your head.
- While drilling, the tool must be held firmly and level. There are times when the drill jams in the hole, and the hammer drill can be torn out of your hands, which can lead to injury. The drill should enter the wall only perpendicular to it (unless special devices), any distortions can lead to part of the wall crumbling.
- It is very convenient when a rotary hammer or drill has an additional handle - this makes it easier and more reliable to hold the tool.

The operating mode for the tool is selected depending on the type of surface you are dealing with. The size of 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 you use to do it, must be stronger than the wall material, that is, you cannot drill through concrete with a wood drill that does not have any additional coating, which is why 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; accordingly, its diameter and depth will depend on this. The photo above shows how a special water-cooled installation bites into the thickness of concrete with a powerful crown - such large holes are needed for the installation of communication lines, ventilation, sewerage and other things. The need for tools that can handle such a task is Lately has increased many times over, since now almost everything is built using monolith technology. For brick walls This is also sometimes required, for example, the builders did not provide for an exhaust hood, or a neat outlet from the boiler needs to be made.
Through drilling of a brick wall
This approach allows us to cope with the problem in shortest time, plus the strength of the wall is not compromised. 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 to broaden our general horizons.
Table 1. Instructions for drilling concrete.
| Steps, images: | Description |
|---|---|
| Step 1. Drilling a hole for the frame.
Drilling holes for the frame | Good equipment has a frame along which the cutting bit moves in in the right direction. In order to properly secure the frame to the wall, you will need to make a hole in it strictly perpendicular to it. |
| Step 2. Fixing the bed.
Fixing the bed | We fix the frame using 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 rotation speed and axial load. It is very important to choose 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 smooth hole, a 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 dust.
Now from professional tools let's move on to the 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 shock function can cope with its drilling - the impulse from the drill will destroy the material more effectively. Use simple electric drill not worth it. No, you will make a hole, but you will spend about 10 minutes on it, not 10 seconds. Agree, the difference is colossal.
Interesting to know! If the hole diameter is less than or equal to 13 mm, then an impact drill will be enough for the job. Large ones can only be made with a hammer drill.

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

Next important point– this is the selection of a drill. Concrete and other hard materials, such as brick, can only be drilled with carbide tools - Pobedit drills. A very durable one will win; a drill tip is made from it, after grinding it down, the device becomes unusable.

Having prepared everything you need, you can start working:
Step 1. First we need to do some preparation. The main problem may be the presence at the drilling site electrical wiring or water supply and heating pipes. To avoid an accident, you need to make sure you don't get caught in them. A metal detector or a special device that responds only to wiring can help in this matter. Pipes inside walls, if they are made of polypropylene and other polymers, will be found by a metal detector only if they have metal reinforcement. Otherwise, you need to look at drawings or photographs of communication lines.
Metal detector for walls
Step 2. Before drilling, you need to mark the entry point of the drill; for this you can use a pencil, marker or punch, if you need not only marking, but also a hole so that the drill does not slip. Usually, when you start drilling concrete or brick, the drill doesn’t go too far to the side, but it can still lead and the hole moves a little. In some situations this is uncritical, but in others, on the contrary, it is unacceptable, for example, you need to screw a bracket that has a strict arrangement of holes for anchors.
Center punches of different sizes
If the wall surface is decorated with ceramic tiles, then it is even more difficult to start drilling without a center punch, especially if the tile is glossy - the drill will slip over it even more, leaving scratches. If you don’t have such a device at hand, you can replace it classic dowel, which will not bend from hammer blows, or start drilling at the lowest speeds, and only after making sure that the drill goes 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 the hole slightly deeper than the length of the element, literally 3-5 mm. If this is not provided for, it may not go all the way, will remain protruding above the plane of the wall, or will break completely. This feature is typical of dowels due to their shape.
This is what the depth limiter looks like
Step 4. There are very thick walls, and the depth of the hole will not play a special role for them, especially if the dowel has a limiter cap that will prevent it from slipping inside. And there are thin partitions, where overdoing can lead to damage to the finish on the other side, plaster falling off, and so on. In this case it is necessary accurately determine the drill depth. For this purpose, limiters are used in the form of rods, fixed in a special device on the additional handle of the hammer drill. Reliable and accurate, but not always.
There are some instrument models in which the fixation of the limiting rod is poorly thought out. It can slip through the hole, making its use risky and inconvenient. In such a case you can use folk method drilling depth designations.
Homemade limiter made from electrical tape
Take a piece of electrical tape and wrap it at the desired level directly onto the drill. If you need to make many identical holes, then make sure that the edges of such a mark are not pressed down, 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 won’t last very long, as it will quickly be erased and become unnoticeable, especially in the debris that comes out of the hole.
Step 5. When drilling concrete, a lot of drilling waste, or simply dust, is released. When you work in a house that is just under construction, 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 accurately. But we wouldn’t be us if we hadn’t come up with ways to deal with such a trivial problem:
- The photo below shows a hammer drill equipped with a vacuum cleaner and a dust bag. Working with such a tool is a pleasure - with good suction power, virtually no debris will enter the room. It is especially convenient to use it at heights.
Rotary hammer with vacuum cleaner
- Such equipment costs a lot of money, so you can use less radical measures. For example, use home vacuum cleaner. You don't need to tape it to the hammer drill - just have someone hold the tube under the hole while you drill it. The effect will be no 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.
Tool with dust collector
- The simplest method is to use a damp cloth. While you drill, an assistant holds it from below and then carefully removes it. The remaining particles of debris on the wall are wiped off with a clean rag.
- If there is absolutely no one to help you, then you can make such a garbage container envelope, 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 waste will fall inside.

If all the dusty work has been completed and you need to prepare the wall for painting, it will be very useful for the reader. IN this material Let us consider in detail the main types of putties and the tools that will be needed during the work process. And step-by-step instruction applying putty to the wall.
How to drill ceramic tiles and porcelain tiles correctly
Perfectly straight hole in ceramic tiles
If you have ceramic tiles glued to the wall, then the process of drilling it will become somewhat more complicated and will consist of two stages. Let's describe them in order.
First, you will need to prepare all the tools: masking tape, a pencil, a marker, a diamond bit, a pen drill, as shown in the photo above, and an electric drill. Ceramic tile very durable material but at the same time she is fragile. If she gets hit, she splits into pieces, so Drilling it with impact is prohibited. However, it is very easy to drill even without this function - just high speeds and a special drill.
Table 2. Instructions for drilling ceramic tiles.
| Steps, photo: | Description: |
|---|---|
| Step 1. Marking on tiles.
Marking | The first step is accurate marking. 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 out and stops writing. Its tip also becomes frayed, which makes it difficult to make accurate marks. In some situations, a pencil helps out, but on glossy tiles it writes poorly and is practically invisible. Masking tape will help out in such a situation. We glue it to the intended drilling location 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.
| We clamp the feather drill in the chuck. It is very convenient to use a second tool for this, in addition to a hammer drill. A screwdriver will suffice. Interesting to know! Masking adhesive tape not only allows you to make precise markings, but also drills 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 realize that the drill has begun to penetrate, we squeeze the maximum out of the tool. If you feel that the drill bit has fallen under the tile and touched the concrete, stop working and remove the tool. |
| Step 3. We drill concrete.
| Continue working feather drill This is not possible, as it will become dull very quickly. To go deeper into concrete or brick, we will again need a hammer drill. Since the tile is already drilled, we will not be able to damage it with a blow from 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 more difficult it is to drill.
When it is necessary to make holes for sockets in tiles, and even in concrete itself, diamond-coated crowns are used. They do their job well, but there is one thing important rule, which must always be observed, namely - cool the cutting edge in time. If you allow the tool to overheat, it can burn out and lose all its properties, so it is worth stopping work at some intervals and immersing it in a container with cold water.
Cooling the drill while drilling tiles
You can also supply water directly to the drilling site - for this you need a special water pump or an assistant who will add it as needed.
Often the right tool not at hand. In such situations, alternative devices or original folk methods can help out.
- If you don't have center punch, which is simply desperately needed when drilling porcelain stoneware, for example, it can be replaced with guide pads like those in the photo. You can buy them in a store, or make them yourself from a piece of plywood or similar material. You can simply hold such an overlay with your hand so that the crown cannot move anywhere. As soon as we pass the first millimeters, it can be removed to the side.

- There are situations when you need to drill through tiles at an angle of 45 degrees. How is it even possible to do this without damaging the surface? Special guides are sold for this purpose. The principle of its operation is this: first a perpendicular hole is made in the usual way , then the stop is immersed in it, after which the drill is transferred to an inclined guide. Naturally, different guides are used for drills of different diameters.
A set for drilling porcelain tiles with crowns will be needed for smaller holes
- What to do if you need to drill a hole for an socket, but you have nothing at hand except a drill. It's okay, they can do the job too. To do this on the wall you need make precise markings of the hole contours. After this you need the entire circumference drill with a minimum step, as shown in the photo below. Next, the inner part is knocked out using a spatula with a hammer drill or a chisel and a hammer.
Drilling large diameter holes without a crown
- If while drilling you come across metal, then you won’t be able to take it with a concrete drill. Here you need to act differently - either move the hole a little to the side, or overcome the obstacle with the required drill, we cut it down with an engraver, a grinder, and so on.
Annoying nuisance
- Look at the photo below and appreciate the method that the master came up with. He simply assembled a corner from a Lego constructor and placed it in Right place, pressed down and did all the work exactly. Let's develop the idea - to prevent such a device from slipping on glossy ceramics, you can stuff plasticine or mastic inside, for example.
The resourcefulness of people knows no bounds
- From homemade products back to professional equipment. It is very convenient to use the suction cup guides. They are securely fixed on ceramics, but only with a flat surface, so this device cannot be called universal. The photo shows a model with indent adjustment.

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