Can I use an impact drill to drill through concrete?
When it is necessary to drill a hole, it is worth first making sure that there are no wires, built-in pipes or cables in the selected location. An easy way to find such elements is to use a metal detector. The wall is almost always present armature, it is better to set the metal detector on non-ferrous metals (search for wiring), and then on steel. If the condition is ignored, there is a risk of bumping into rebar, the pobedite drill bit will be hopelessly destroyed.
Initially a dot is marked on the wall. To prevent the tool from slipping, make an indentation with any strong metal object or drill at low speed. After careful preparation, the drill for concrete easily enters the wall. It is worth taking into account that on top of the cement is applied facing. it is softer than the wall itself, which means that initially the drill goes easily, then rests on the solid material.

How to drill a concrete wall with an ordinary drill or peorator: recommendations
How to drill a concrete wall with an ordinary drill?. this is the question many craftsmen have asked when they had to hang shelves, cornices and so on.
Concrete is a tough material and therefore lends itself to drilling extremely poorly. Even how to drill a wall in a panel house, the task may seem unsolvable.
Although, if you know certain secrets, this process can be greatly simplified.
Choose a tool
So, the first question a home handyman should ask himself is not how to drill a concrete wall with rebar, but with what. The main helper in this case will be a peorator, because it is intended for stone and concrete. At the same time, even powerful drills can not cope with a wall width of more than 12 cm. Although when it comes to foam concrete, the drill is preferable, because the tool will simply break it.
On the quality of the drill bit also depends on whether you can drill a hole in a concrete wall.
One of the best options is to use drills designed specifically for impact drills. Their working part is a plate made of hard metal. With these drills the question of how to drill a thin concrete wall can be considered solved.
There are also ring drills, which have a diamond coating. They are very strong, they are used in special drilling rigs, so they cost quite a lot. Therefore, to solve their problem, how to drill a hole in a concrete wall at home, it is impractical at least.
Using drill bits
It is often necessary to get a large-diameter hole in the wall for a socket. How to drill a load-bearing wall in this case? Then they use bits that have metal tips around their circumference. Drill bits come in a variety of sizes, but the most popular are 68-centimeters, which are designed just for the sockets. Working with these parts, it is necessary to turn off the impact mode.
There are also drill bits for drills. But they have a different kind of sputtering. of cobalt-tungsten alloy. It is convenient to use them, because to drill a hole in the wall of concrete with a drill and simultaneously make a hole in the tile she is quite able to. Such bits are used only with powerful drills.
Drills. another device than to drill a concrete wall. Their diameter is varied. Experienced craftsmen advise to make a selection, based on the diameter of dowels.
Drilling Concrete with a Peorator
So, how to drill a hole in a concrete slab with a peorator? The procedure is not complicated:
- the drill switches to percussion mode, and then drilling begins; the tool must be held strictly at right angles;
- after some time, wet the drill bit with water, this will help avoid overheating;
- after drilling a reinforced concrete wall is successful, the drill bit, without turning off the machine itself, must be removed;
- To clean the resulting hole of dust, a drill is run into it several times.

I can’t drill through the wall? The drill has hit something hard? So we have to try to make a hole somewhere else.
We’ll do it with a drill
How to drill a concrete wall without a drill? The question of using an ordinary drill when working with concrete remains unresolved. So whether you can drill through a concrete wall, everyone decides for himself. The tool can break, after all. And the procedure takes longer.
Drill a hole in the concrete with a drill, you can use a special tool. a puncher. It is simple to operate: put the sharp end to the place where the hole will be located, hit it several times with a hammer, and then you can start drilling.
It is important not to overheat the tools.
As soon as the drill comes across an insurmountable obstacle, it is necessary to engage the puncher again until the desired goal is reached. Here’s how to drill a concrete wall correctly with a drill. Although it takes more time and effort, you can also use it if you don’t have a torch.
This is another easy way to drill through a concrete wall. However, only professionals with special equipment (high-powered electric motor and the like) use it.
How to drill a frame wall? This is not a problem, because diamond drilling allows you to get a hole of large diameters and depths, and without irritating eye dust. In parallel, water is applied directly to the drill bit, which cools it down. As a result, the resulting holes have a neat appearance, and the appearance of cracks is completely excluded.
How to drill a tile so that it does not crack? See here. What is a drilling guide? Read in this article.
Drilling of concrete walls by this method is usually made by professionals of specialized firms. So it does not make sense to stock up on a diamond drill rig for self-drilling.

How to drill concrete with a drill?
Often the concrete surface has to be drilled and dismantled. This requires efficient and safe tools that will not damage the surface and can make a neat hole. A drill is ideal for drilling a concrete surface, but you need to learn how to use it. Let’s consider how to properly prepare the tool and surface for repair work.
Concrete structures are very strong, so it is quite difficult to drill them yourself.
This is due to the fact that for the creation of concrete products is used rubble, and when during drilling, you get on it, the process is greatly hampered.
The need to drill a concrete wall occurs quite often, it is necessary for the installation of shelves, cabinets, air conditioning, wallpapering, fixing light fixtures, when attaching insulation or during plastering walls to fix beacons.
There are several ways to solve this problem:
To create large-diameter holes or cut through a doorway, diamond-coated ring 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 professionals or you can rent it.
Impact drill and peorator. what are these tools for
To find out what the difference between an impact drill and a peorator, it is necessary to clarify their functional purpose. Let’s consider each tool separately:
- Impact drill or hammer drill. this is a popular type of electric tool, which almost every craftsman has. It is used to drill holes not only in metal and wood, but also in concrete. To drill solid concrete, you must activate the impact drilling mode on the tool, otherwise the drill will not go deep into the material. If there is no percussion mode on the tool, then it is not designed for drilling concrete, bricks and stone
- Peorator or drill hammer is a professional type of tool that is designed directly to perform chisel-drilling work on concrete. Pistol-type devices have a mode switch, among which there is a drill on. Enabling this mode enables the tool to be used for drilling holes in metal and wood. But the pliers are mainly designed for work on high-strength materials like concrete, stone, bricks, etc.п.
When the craftsman drills a hole in concrete with an impact hammer, he needs to apply pressure to the tool. And the amount of force you apply has a direct impact on the speed at which you get the result. Unlike an impact drill, the rotary drill does not need to apply pressure, so the operator only has to guide the tool and hold it in place.
Choosing a tool and working with it
When choosing a tool to drill a hole, you should understand that your job depends on it. A good drill accurately drills a concrete wall, or other necessary material, simplifies the drilling process, while a bad drill will require a lot of time, may not cope with the task, or complicate it. What you should pay attention to when choosing a drill:
- Is it possible to change the drilling speed??. this point is important because adjusting the speed will ensure that the drill bit works accurately, helping it not to damage the surface.
- Is there a possibility of percussive drilling and depth control?. Percussive drilling can be used on problem areas by softening them.
- Is it possible to hold the drill with both hands??. a drill is not a light tool and therefore preference should be given to models that are equipped with handles.
- Whether the power of the tool is satisfactory for your job?
After deciding on a drill, you need to get used to holding it before you start working. To do this, take the drill in one hand as if it were a pistol, the other hand is placed on the handle of the tool (if it is not intended by the design, the hand is placed near the chuck). The drill must be held horizontally in the hand so that the hole is not tilted or at an incorrect angle. Wait until the drill has reached ambient temperature before turning it on. Sudden temperature fluctuations can provoke condensation. If you decide to rest during the work. unplug the tool.
Before you start drilling, you must make sure that there are no wires, pipes, electrical cables in the chosen location of the slab. A metal detector can help, since it reacts to non-ferrous metals, iron and steel.
If you ignore this condition, you could bump into rebar, damage the drill bit, or cables/pipes that have been hidden in the slab. If the area meets all of the above requirements, then a point is marked on the wall, and then. in it, a small hole is made at slow speed with the drill. It is also worth remembering that the surface of the concrete wall is more loose than subsequent layers.
Drilling in concrete with an impact drill
How to drill concrete? This question often arises during construction or repair work on houses with concrete walls. Drill concrete has to install electrical outlets and switches, lay pipes, wires and other communications.
When drilling concrete, the beginner faces a host of problems, such as drill breakage, or even a drill.
Concrete is a very strong material. It is very difficult to drill with conventional methods. And if it is reinforced (reinforced concrete), this task becomes almost impossible with an ordinary drill. How to drill through concrete? The problem of making holes in this material is becoming more and more popular.
What to drill concrete with?
The main tools for drilling such structures today are a drill, equipped with an impact mechanism, and a peorator. The right way to drill concrete with a peorator. It is designed precisely for this kind of work. Holes made with a percussion drill can be quite large in both depth and diameter. It is possible to drill through the wall using special working tools with a tungsten carbide coating or with pobedite inserts. There are several common uses for this tool:
The most powerful tool for drilling in concrete is the peorator.
- The use of conventional tools with the additional use of a puncher;
- Using a rotary or impact drill fitted with special tools;
- drilling with diamond tools.
Making a hole in the wall in a normal way is very difficult, and it takes a long time. The tool dulls quickly and fails. How to drill a wall correctly? The drilling point must be constantly rotating and percussive. A rotary motion is achieved with a drill, and a percussive motion with a punch and hammer. An old drill bit can be used as a puncher. The hammer is struck on its face. In doing so it partially destroys the concrete layer. Destroyed particles are removed with a drill. The hole gets deeper, but slowly. The most common method. making holes with a torch and special cutting tools. The work is carried out fairly quickly and with high quality. Small amounts of work can be accomplished with an impact drill and carbide tools.
Diamond drilling is used for quite large amounts of work. This method allows the work to be done very quickly and without much dust. How to get the hole of large diameter? This is done with diamond or carbide tipped bits. Special machines with a water vacuum cleaner are used in some cases. But this can usually be done with a torch. It is recommended to periodically remove the drill bit from the hole and moisten it with water.
Drill chucks are available in diameters of 4 mm and upwards. the largest diameter is 1.2 cm. They can be up to 40 cm long. A plastic dowel is inserted into the prepared hole, and a self-drilling screw is screwed into it. The diameter of the dowel must match the diameter of the hole. For suspending cabinets and other pieces of furniture, it is recommended to drill holes and use 8 mm diameter wall plugs.
The drills used in the perforator are commonly referred to as drills. Drill bits can be 4 mm to 28 mm in diameter. At the same time, they have different lengths (diameter and length in millimeters):
Drill bits have an SDS-plus shank. Other shank diameters may be used in industrial installations. To make holes with a diameter of 35 mm or more, you use tools that are popularly called drill bits. Their maximum diameter is 12 cm. On the perimeter of the drill bit there are tips of pobedite or diamond coating. The drills are used without a hammer mechanism. The hole is drilled in several steps to allow the cutting tool and motor to cool down. Drill bits drill well into tiles, so tiled concrete walls can be drilled without changing tools.
to buy special augers and core bits at numerous tool and construction equipment stores.
- Before fixing the tool in the chuck of a torch or a drill, clean it from dirt.
- The core bit’s shaft must go all the way into the chuck.
- For household drills and rotary hammers you must take a break for 10-15 minutes every 15 minutes.
- It is recommended to periodically moisten the core bit with water.
- Before you drill holes in the wall make sure there are no pipes or wires in the wall.
- To find pipes and wires in the wall, you can use a metal detector.
- Start the drill with the hammer mechanism turned off and on low speed.
- The depth of the hole should be slightly greater than the length of the dowel to be inserted in it.
- The drilling depth can be noted by taping a coil of electrical tape over the drill bit.
- When working, it is recommended to use personal protective equipment.
- It is better to buy drills from reputable manufacturers. Bosch products are a great choice.
- Diamond tools help to drill many identical holes quickly and accurately.
- Concrete drills and drills should not be used when drilling metal and wood.
Drilling concrete walls is not very easy, but it is doable even at home.
Drill holes are often necessary for installing kitchen cabinets, plug sockets, switches and junction boxes for the installation of the electrical system. Good drills and core bits, a torch and an impact drill are needed for the work. everything else is a matter of time. The skill is acquired very quickly.
Design features of drills for concrete drill
Initially, you need to find out how the drill bit for concrete on the drill to make a hole in the wall. To implement the idea, you will need a drill with an impact function. Exactly for an impact drill it is necessary to select a special drill bit for drilling concrete. In normal drilling mode, the tool will not be able to cope with the task without a hammer.
Everyone knows what an ordinary wood and metal drill bit looks like. For drilling in concrete, a similar design of nozzle is used, only with a slight difference. the presence of tungsten carbide on the tip, head, or working part. These tips are designed to pierce the wall, and at the same time increase the life of the cutting tool.
Concrete drill bits are coated with tungsten carbide, which is a combination of tungsten alloy and cobalt. This tungsten carbide is only on the bit head, which is directly involved in contact with concrete and other similar materials. An alloy of tungsten and cobalt makes the cutting head tough, reliable and resistant to cutting edge abrasion.
In addition to pobedite, manufacturers also produce tooling on the concrete for the drill with a soldering, or more precisely, a dusting of diamond. Such bits are even more reliable when working with tough materials. They may even be used for drilling in reinforced concrete because of their high cutting properties.
Distinctive features of concrete drills are not only in the head design, but also in the shank. The shank is the part that is sunk into the drill chuck, and is clamped by the legs of the mechanism.
It is by the design of the head that you can distinguish the concrete drill bit from other metal and wood drill bits. Before you choose a pobedite drill bit for a drill, you need to understand their types and design parameters.
