How to drill concrete with a drill?
Each of us has repeatedly faced the need to mount various objects on the walls that add variety to the interior, create coziness, or simply remind us of the pleasant moments of life. Most often, you have to fix lamps and sconces, paintings and photographs, mirrors and shelves to a concrete surface, install an air conditioner, or a TV. If, in the case of a small picture, or a photograph, you can do with driving a nail into the wall, then when the question is about more massive and heavy objects, the question of drilling holes arises. In order to avoid misunderstandings when working with concrete, for example, breakage of a drill, dullness of it, it is worthwhile to competently prepare a partition, choose a quality tool and choose the right drill.
Drill selection
This point can rightfully be considered the main one, since the quality of work and the safety of the drill itself, as well as the accuracy of work, depend on a properly selected drill. Today, there is a huge variety of different drills on the market: for working on wood, metal, concrete. The latter are distinguished by a triangular tip. For a concrete surface, it is best to use a carbide drill, for example, a victory drill. This type of drill crushes the material without tearing it, which is ideal for concrete slabs.
If in the process of drilling the wall the drill does not go forward, encountering a dense area, it is recommended to use a punch. After inserting a punch into the hole, they beat it with a hammer until it starts to move forward and softens the problem area. Then you can continue drilling.
It should be noted that without a punch, a perforator can easily cope with this kind of difficulty, however, it makes holes that exceed 13 mm in diameter. If you want to use universal drills when drilling, you need to remember that they require cooling, vibration off and are only suitable for a conventional drill.
Surface preparation
Before you start drilling, you need to make sure that there are no wiring, pipes, electrical cables in the selected overlap location. A metal detector will help to cope with this task, as it reacts to non-ferrous metals, iron and steel.
If you ignore this condition, you can stumble upon fittings, damage the drill, or cables / pipes that were hidden in the ceiling. If this section satisfies all of the above requirements, then a point is marked on the wall, and after that a small depression is made in it at a slow speed with the help of a drill. It is also worth remembering that the surface of a concrete wall is looser than subsequent layers.
Choosing a tool and working with it
When choosing a tool to drill a hole, you should understand that your work depends on it. A good drill accurately drills a concrete wall or other necessary material, simplifies the drilling process, while a bad one will take a lot of time, may not cope with the task, or complicate it. What you need to pay attention to when choosing a drill:
- Is it possible to change the drilling speed?. this point is important, since the correction of the speed mode will ensure the accurate operation of the drill, helping it not to damage the surface.
- Is it possible to hammer drill and adjust the depth?. hammer drilling can be applied to problem areas, softening them.
- Is it possible to hold the drill with both hands?. the drill is not an easy tool and therefore models that are equipped with handles should be preferred.
- Is the power of the tool sufficient for your job??
Having decided on the drill, you need to get the hang of it before starting work. To do this, take the drill in one hand, like a pistol, place the other hand on the tool handle (if it is not intended by the design, the hand is placed near the cartridge). It is necessary to hold the drill in your hands strictly horizontally so that the hole does not work out with distortions and at the wrong angle. Wait until it reaches the ambient temperature before turning on the drill. Sudden temperature changes can cause condensation. If during work you decide to rest. disconnect the tool from the mains.
Power selection for drills
The optimal power for working on concrete, in order to drill a hole, is considered to be a power of at least 600 W and 2500 rpm, but this figure must be adjusted depending on the manufacturer’s recommendations so as not to spoil the drill. As already mentioned, concrete “crumbles” when we drill, and this does not require too much speed.
A little about the device of the drill and the installation of the drill
The classic drill consists of a power cable, a button, a capacitor wire, a reverse, brushes and springs, an armature, a stator, a gearbox and a chuck, bearings, a key and fastening screws. Correctly inserted drill improves the quality of drilling, and is able to secure it.
The first thing to check when starting to work with the drill is whether there is any dirt on the drill itself. When cleaning drills, a rag will be an excellent assistant. If the drill is loose, there is a risk that it will fly out and injure the master. Accordingly, it is necessary to immerse the drill as much as possible in the chuck (all the way!).
Do not under any circumstances try to “lengthen” the drill by incomplete immersion in the chuck.!
It is important to ensure that the drill in the tool is fixed strictly along the axis. If this rule is not followed, drilling in concrete will be of poor quality, the shape of the hole may be unpredictable, and the cause of all these misunderstandings will be the elementary beating effect of the drill.
Drill errors
Never try to hold the rotating chuck with your hand. there is a drill body for this. Otherwise, you could injure yourself. If you use gloves, do not take “with a margin”. Inappropriate gloves can also get caught in the cartridge and cause injury. Overalls should not be loose. they can be rolled up or pressed with oversleeves.

How to drill concrete?
Concrete drilling tools
First of all, you need to decide on the tool. Basically there are two options: impact drill and hammer drill. Of course, it is best to choose a hammer drill, because the initial task of this tool is precisely to punch holes in concrete or stone. With its help, you can make holes of a sufficiently large diameter, while even the best hammer drill is not designed for drilling passages thicker than 12 cm.But if you are going to drill foam concrete, then a drill is preferable in this case, since the hammer drill will simply break the wall. Remember that you cannot use an ordinary shockless door for work, since this is not only useless, but can also lead to tool breakage.
If you need to make several holes, then in the absence of a punch, you can also use a drill, but if you have a long work ahead, then its acquisition cannot be avoided. Here, first of all, we are talking about saving time and effort, because the drill is not designed for such heavy loads. But if you still have to work with this tool, remember that in this case, use a victorious drill for concrete, the tip of which is coated with carbide spraying.
Concrete drilling methods
At the moment, at least three methods are well known in the construction industry, with the help of which it is possible to drill holes in concrete, even in spite of built-in reinforcement. We are talking about using a conventional drill and drill in combination with a punch (pin, core), impact drill or hammer drill with special drills for concrete, as well as diamond drilling.
You can drill a concrete wall with a conventional drill, which is used when working on wood and metal. The drill in this case should be different from a regular tool, don’t even think about a regular drill. For work on concrete in our time, drills with a special soldering from a particularly hard alloy are usually used (such an alloy is called pobedit). When drilling concrete in this way, it is necessary to adhere to a certain sequence of operations. It is worth noting that this method is the most laborious and less qualitative among all due to the complexity and rather long duration of work. To make holes, various cuts and grooves in a concrete structure, it will be necessary to provide a variable combination of impact and rotational effects on the drilling point. Therefore, the installer in the place for the future dowel will have to alternately knock out a part of the concrete with a punch, and then remove this mass with a conventional drill with a victorious drill. To do this, take a metal punch (pin, old drill, core) with a size equal to the diameter of the required hole, then insert the punch into a small recess previously made with a working drill. The top layer of concrete is crumbled with hammer blows on the end of the punch, then the resulting hole is partially deepened by the door. Such operations must be repeated until you reach the required hole size.
At the moment, the most common way is to drill concrete walls with a hammer drill or hammer drill. In this way, you can quickly and efficiently do the job. In doing so, try to pay attention to the reinforcement that can be built into a concrete wall or any other concrete structure.
It is advisable to choose an impact drill for small amounts of work, while no additional devices and tools are required. It is enough just to transfer the work of the drill from the usual rotary to the shock-rotary mode. If you have to drill a wall from a particularly durable material, then it is best to use a puncher. Drilling in this way has many advantages over hammer drills. A drill inserted into a hammer drill chuck is much easier to bite into a wall, so you can drill concrete much faster.
This result is attributed to several factors. A hammer drill is an electromechanical tool with more power, while its chuck rotates at a slower speed than a drill chuck. However, the hammer blows, which are produced by the electro-pneumatic mechanism, have more force, which is why it drills walls faster and easier. In addition, due to the impulse of a special striker, the amplitude of the forward motion of the drill in the hammer drill is large enough, and it does not depend on human efforts. In an impact drill, this indicator is much lower, since the impact movements of the drill are provided by the interaction of special ratchets with small teeth. In addition, for better drilling, the installer will have to exert great physical effort by pressing on the drill.
It should also be noted that the high rotational speed of the hammer drill chuck, combined with the minimal dimensions of the ratchet teeth, can lead to their rapid wear. Therefore, it is best to choose, although expensive, but also more reliable and durable rock drills.

Drilling a wall with a drill
The hammer drilling process 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 whole procedure for making a hole with a drill consists of the following steps:
- The place of the future hole is marked on the wall. A punch is placed on the mark, hit sharply 2-3 times with a hammer.
- After impacts, a small crater forms in the concrete. A soldered drill is inserted inside the recess, the drummer mode is turned on on the drills, 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 deepening for two reasons: solid fractions of concrete or reinforcement have fallen into. Drilling is stopped. A punch is inserted inside the funnel, sharp blows are applied with a hammer. When the solids are destroyed, continue drilling. If the reinforcement hits, it is better to move the hole to the side. If this option is not suitable, the rods are handled with a diamond crown or a drill for metal.
Actions continue until the desired hole depth is reached.
How to drill a concrete wall with a conventional drill
A perforator is intended for drilling concrete, but in its absence, in many cases, a hand-held electric drill will cope with the work. You can achieve success if you choose the right drill or crown. To figure out how to drill a concrete wall with an ordinary drill, you need to know a clear algorithm of actions, take into account a number of important nuances of drilling.
A little about the device of the drill and the installation of the drill
Most drills, regardless of manufacturer, include the following main structural elements:
- body;
- reducer with a chuck;
- stator;
- bearings;
- anchor;
- brushes equipped with springs;
- power button;
- regulators;
- screws;
- reverse system;
- network connection cable;
- the keys.
In more expensive models, additional structural elements may be present. It is extremely important to properly secure the drill in the chuck, because not only quality depends on this, but also the safety of work. If the tip is not tightened enough, it is likely to fly out of the cartridge, which can cause injury.
Before starting work, it is advisable to check the correct attachment of the drill in the center along the axis. Even a slight offset will cause a larger hole to be drilled than necessary. In addition, before starting work, wipe the drill with a rag to remove any dirt.

Choosing a tool and working with it
A high-quality powerful tool helps you drill a hole not only quickly, but also accurately. An impact drill copes with this task better, which allows not only drilling out concrete, but also crushing it if necessary. It is convenient to use an impact drill if several layers of concrete mortar are applied to the surface.
In hammer mode, you can drill a hole even in thick concrete. There are a number of other parameters that you should pay attention to when choosing a tool.
It is desirable that the tool be equipped with a speed regulator. It allows you to adjust the speed. This will allow for more accurate work. When the device is turned on at maximum speed, it is possible to drill holes of large diameter, but there is a possibility of chips and other defects. It is desirable that the device be equipped with a speed lock and reverse. In addition, the drill must have a smooth start.
Considering which device is better, you need to pay attention to the presence of an auxiliary handle. The powerful impact drill is heavy and can be held with 2 hands during operation with the optional handle. Another important parameter that you should pay attention to when choosing a tool is the presence of a drill insertion depth regulator. It makes it easier to control the process of making holes when you need them to be of the right depth.
It is important that when working with the tool it is convenient to hold the drill at right angles to the surface. This will prevent damage to the coating and distortion of the hole. Start working with the tool only after it has warmed up, having worked for some time at idle speed. This will get the drill ready for use. In addition, it will reduce the risk of condensation forming inside the tool due to sudden temperature changes.
Power selection for drills
The optimal power for working on concrete, in order to drill a hole, is considered to be a power of at least 600 W and 2500 rpm, but this figure must be adjusted depending on the manufacturer’s recommendations so as not to spoil the drill. As already mentioned, concrete “crumbles” when we drill, and this does not require too much speed.
Some helpful tips
Before starting work, you should stock up on nozzles for drilling not only concrete, but also metal, because in the process of work, drilling of reinforcement may be required. During operation, it is necessary to monitor the degree of heating of the device. Overheating should not be allowed. You need to take a break every 15 seconds, letting the device cool down. Drills made from a relatively soft material require periodic sharpening.
If it is necessary to make a hole for the further installation of a plastic dowel, a longer drill should be taken. This will avoid incorrect placement of the dowel due to accumulation of dust inside. You should start working at low speed. This will make the drill easier to control.
If you need to drill a concrete wall without harming the decorative ceramic coating, you should not use the impact mode, because this will damage the tiles. In this case, you need to use a special ceramic attachment. This will help to make a neat hole and avoid damage to the tile.
