What do the professionals advise?
Concrete structures are strong enough and difficult to drill. In addition, drills quite often come across crushed stone, which is part of the concrete mixture, from which wall and ceiling slabs are formed..
Holes in concrete have to be made quite often, especially in the process:
- finishing works;
- furniture installation;
- air conditioner suspension;
- additional electrical wiring device;
- plumbing installation.
There are two ways to solve the problem of holes in a concrete wall:
- with an impact drill, or better with a perforator, 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.
How To Drill A Hole Without A Drill
What will help the home master?
In domestic conditions, when it is necessary to make 2-3 holes in concrete, you can do with an ordinary drill, without the impact 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) that matches the size of the hole diameter. 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 hit 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 increases 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. Professional advice – to avoid overheating the drill, it should be moistened with cold water from time to time.
How to choose a tool?
For more work, you need a hammer drill or drill with an impact function, and drills with victorious tips. 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 to drill a concrete wall – a possible way out of the situation
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 is no secret that every home craftsman has encountered this problem at least once in his life, but not everyone knows how to solve it. Many courageously torture the drill and their own strength, but without achieving the desired result, they abandon 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 them and be able to use them..
Than big holes are 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;
- base-mounted guide post.
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.
With diamond drilling, the holes are precise in shape and clear in outline, with a polished inner surface. They can be made in various enclosing structures at any angle to the horizon, and the possibility of cracks or chips in the concrete is completely excluded. Destruction occurs only at the location of the future hole.
Specialized firms are engaged in diamond drilling, so if it is necessary to drill holes in concrete of large diameters, you can invite craftsmen with their own equipment. And it is not necessary to buy a diamond drilling machine specially for this..
DIY drill
The best suited for this operation are small hand drills, the likeness of which you can make yourself. To do this, two laces and a handle are tied from above to a rigid axis, which can be a steel or wooden rod, and from below. sharpened carnation. In the middle of the rod, you need to fix a heavy flywheel, which will act as an inertial battery. In order to put this drill into action, the laces are manually wound on the rod, and then, having set the nail in the right place, they press the handle. The rod rotates and the nail drills, the pressure on the handle is stopped when the laces are completely unwound. The flywheel rotates by inertia and again winds them onto the rod, and then stops and you need to press the handle again. Viscous wood species may not succumb to such a drill, as the drill will get stuck and slow down the rotation..

The easiest way to get these holes is to use an awl with a diameter of 1 to 3 mm. It is easy to make an awl from a thick needle or even from a trim of piano wire, the length of which is about 5 cm. The needle or wire is first driven into a piece of hardwood half the length, and a handle is subsequently made from this tree. The end of the wire remaining outside is sharpened on 3 or 4 edges. A well-made awl acts in this case like a drill, piercing the wood, it is rotated and it cuts and twists the wood fibers, and does not just push them apart..
DIY screw drill
For the construction of a screw drill, a rotation mechanism from a children’s top is well suited. Instead of a cartridge, a compass pencil holder works well. When lowering the engine with the same thread by hand, the screw axis of the drill begins to rotate. With this mechanism of action, the drill head must necessarily rotate on the axis freely.
If the top is not at hand, the screw of this action can be bent by yourself. To do this, you need a strip of steel, one end of which must be fixed in a vice fixed on a machine or on a table, and the other end must be fixed in a manual vice. When the hand vise is rotated, the strip will evenly twist into a screw, onto which a wooden slider with a pre-drilled hole is then mounted. In order for the engine to have no difficulties when passing the helical surface of the strip, the strip is heated and, passing through it with the engine in this state, a thread is made on the strip. For making a hat, a small wooden ball is suitable, in which a hole is made in diameter slightly larger than the diameter of the screw.
Diamond drilling
This is another way how easy it is to drill through a concrete wall. However, it is used only by professionals with special equipment (high-power electric motor, etc.).
How to drill a framing wall? This is not a problem, because diamond drilling allows you to get holes of large diameter and depth, and without dust irritating to the eyes. In parallel, water is supplied directly to the drill, due to which it is cooled. As a result, the holes obtained are distinguished by a neat appearance, and the appearance of cracks is completely excluded..

Drilling of concrete walls using this method is usually carried out by professionals from specialized firms. In the overwhelming majority of cases, when installing hidden electrical wiring, you cannot do without such a dirty and noisy procedure as chasing. So it makes no sense to stock up on a diamond drilling rig for independent work..

How to drill without dust: the options are better
Construction work is always accompanied by dust and debris, but using some guidelines and tips, it can be significantly reduced:
- the hammer drill leaves little dust during operation so that it does not scatter around the room at the same time use a construction vacuum cleaner. Some brands of tools have a built-in vacuum cleaner, which makes the task easier;
- using a drill, it is best to either make a jig on the end or a bag, or make an envelope under the hole so that debris falls into it.
Perforator
The puncher is a versatile tool. It can be used to make a hole in a wall made of wood, tiles and concrete..
The tool has several functions – drilling, hammer drilling and hammering mode. To make a hole, you need to select the desired drill depending on the surface and perform the work by selecting the mode.
There are also hole drills that are diamond coated. They are very strong, they are used in special drilling rigs, and therefore they cost a lot. Therefore, they solve the problem of how to drill a hole in a concrete wall at home, it is impractical at least.
Features of the
Concrete structures are highly durable, so it is quite difficult to drill them yourself..
This is due to the fact that crushed stone is used to create concrete products and when you get on it while drilling, the process becomes very difficult..
The need to drill a concrete wall occurs quite often, it is necessary for the installation of shelves, cabinets, air conditioner, wallpapering, fixing a lamp, when attaching insulation or during plastering of walls for attaching beacons.
There are several ways to solve this problem:
- using a hammer drill or a powerful impact drill;
- an ordinary electric drill or screwdriver;
- diamond drilling.
It should be remembered that for walls made of relatively soft materials, it is impossible to use victory drills, since the holes will turn out to be uneven, and the wall will collapse. It is also impossible to work with metal with such a tool..
To create large holes or cut a doorway, diamond-coated core drills are used. To use such a tool, it is necessary to use special installations, they allow you to make holes with a diameter of up to 250 mm.
Since the cost of such equipment is high, it is easier to hire specialists or you can rent it..
Drill
The tool is suitable when you need to make multiple holes. You can use a conventional drill. When plunging a victorious drill into the body of the wall, sometimes it is necessary to break the concrete with a punch, which coincides in diameter with the hole. This is necessary when the drill starts to get stuck in the surface, bumping into too dense areas. The process is quite laborious.
For greater efficiency, you can use universal drills that are diamond-coated. They are installed only on a conventional drill or on a tool where the vibration function is disabled..
For large-scale work, an impact drill and drills with victorious tips are used. They are designed for holes up to 12 mm. The drill is suitable for working with metal, concrete.
Tools for work
For work, they use different tools, the main ones: a drill, a perforator, a screwdriver. There are nuances when using each.

In most panel houses, the walls are made of concrete, to make a hole with a hammer drill, you need to use a drill bit..
In addition to them, you can use special crowns. They have soldering around the circumference. When using them, you need to turn off the percussion function of the punch.
Experts use diamond drilling, this requires powerful equipment and skills.

Screwdriver
The screwdriver is one of the most popular tools for repair and construction work. It can be used to twist and unscrew self-tapping screws, drill wood, metal, chipboard, plywood, tiles, plywood, lightweight concrete.
Which attachments to choose
A specific nozzle is used for each material:
- concrete, brick, stone – a drill with a carbide plate or a victorious one;
- tile, glass – cone-shaped drills with diamond dusting;
- metal – spiral drill with a cylindrical cone;
- wood, drywall – for holes of different diameters, drills are used: feather, ballerina, screw, saw crowns for wood;
- foam concrete – victorious drills.
How can a large drilled wall be repaired?
You can fill in unnecessary holes in the wall using a special building mixture. It provides strength and durability. The composition must be selected depending on the area and type of defect.
With the help of putty, you can level the surface, including concrete. There are several types of putty:
- cement – used in exterior and interior decoration, suitable for concrete. Durable and moisture resistant. It dries for a long time and often with a mesh, which requires reapplication;
- gypsum – used in dry rooms, is not resistant to water and is afraid of temperature extremes. Does not crack when applied, therefore, it can be applied immediately in a thick layer;
- acrylic – finishing. It should be applied in a thin layer, therefore it is suitable for small imperfections.
None of the mixtures are used to seal through holes.
Polyurethane foam is a versatile material. There are one-component (used without preparation) and two-component (when using a construction gun or mixer).
When applied, the foam expands and fills the required space. Freezes and gives a high-quality density. Deep holes can be closed.
The repair mixture is suitable for repairing large defects. Has good adhesion, frost-resistant, strong and durable.
When deciding to make a hole, carefully read the rules and recommendations. Choose a tool, depending on the composition of the surface, and the drill. If you are not sure of your own skills, then entrust the work to specialists.
