How to Drill Concrete with an Ordinary Drill
Sooner or later, most people living in houses with concrete walls need to hang a cabinet, a lamp, a shelf or a picture. At this point, the urgent question arises of how to drill a concrete wall. It is no secret that every home master at least once in his life has encountered this problem, but not everyone knows how to solve it. Many courageously torment the drill and their own strengths, but, not achieving the necessary result, they drop everything until the next attempt to make a hole in the wall. But the drill eventually breaks, and the shelves still stand somewhere in the corner of the room or gather dust in the pantry. But there are still options. you just need to know them and be able to use them.
What do professionals advise?
Concrete structures are strong enough and difficult to drill. In addition, quite often drills come across crushed stone, which is part of the concrete mix, from which wall and ceiling plates are formed.
Holes in concrete have to be made often enough, especially in the process:
- finishing work;
- furniture installation;
- air conditioning suspension;
- an additional electrical wiring device;
- installation of plumbing.
There are two ways to solve the problem of holes in a concrete wall:
- impact drill, and preferably a puncher, with a drill;
- diamond drilling.
It is worth noting that it will not work to make a hole in a concrete wall with ordinary drills, so before you begin, you need to purchase drills with specially soldered plates made of high-strength victorious alloy, which perfectly cope with concrete and brick. But for soft materials, it is not recommended to use them, since winning drills do not cut them, but crumble them.
What will help the home master?
In domestic conditions, when it is necessary to make 2-3 holes in concrete, you can get by with a conventional drill, without an impact function. For this, it is necessary to submerge the concrete drill with a strong metal pin (punch), which is the same size as the diameter of the hole, as the victory drill is immersed in the wall body. It is used in the case when the drill begins to "stop" in the wall. At this point, a steel punch is inserted into the hole and they begin to hit it with a hammer or sledgehammer, trying to crush too dense areas and punch the hole deeper. In this case, the pin is slightly rotated. Then a hammerless drill can come back into operation.

All of the above steps are repeated one after another until the hole is enlarged to the required depth. This method is quite time-consuming and tedious, but quite acceptable for a pair of holes.
As an option, when drilling holes in concrete, you can use universal drills with diamond spraying. 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.
Work with a drill very carefully, otherwise it will fail too quickly. The advice that professionals give is to avoid overheating the drill, it should be moistened with cold water from time to time.
How to choose a tool?
For a larger scope of work, a perforator or drill having an impact function and drills with drill tips are needed. An impact drill combines rotary with reciprocating motion, which helps it to cope with lightweight concrete, and there is a simple answer to the question of how to drill a concrete wall that is supporting, the best assistant will be a puncher, the main purpose of which is to pierce concrete fencing. There is another difference:
- hammer drill is designed for drilling holes of not more than 12 mm in diameter;
- The puncher is capable of drilling large holes.
Drill reinforcement caught in the body of the concrete wall should be drills for metal.
What drill large holes?
Professionals who are constantly faced with the problem of drilling holes in concrete use special equipment, which includes:
- powerful electric motor;
- drilling drive;
- diamond core drills of different diameters;
- fixed on the base of the guide rack.
Diamond drilling allows you to make holes of large diameter. up to 40 cm. The process occurs quite quickly, efficiently, without excess dust and noise. Water is automatically supplied to the drilling site, which simultaneously cools the diamond crown and rinses off the dust.
During diamond drilling, the holes are precise in shape and clear in shape, 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 concrete is completely excluded. Destruction occurs only at the location of the future hole.
Specialized firms are engaged in diamond drilling, so if necessary, drill holes in large-diameter concrete, you can invite the masters with their equipment. And it’s not necessary to buy a diamond drilling rig specifically for this.
