How to drill concrete: tools, preparation, process
The need to hang a chandelier, install wall cabinets, a wall outlet, etc., sooner or later arises in the life of each owner of the living space. Considering the fact that concrete columns, ceilings and ceilings are quite common for modern apartments, it may turn out that the fasteners have to be mounted on a concrete structure. If you are “lucky”, then it is only natural to wonder how to drill concrete?
Concrete is one of the most durable building materials available today. However, its strength, in this case is the main problem, since it is impossible to drill reinforced concrete without specialized equipment and relevant knowledge. At the same time, the call of specialists for the formation of several small holes will cost you a disproportionately large amount.

If you want to save money, it is quite reasonable to think about solving this problem on your own. Despite the obvious complexity - the right approach and the strict observance of the technological part of the process will help you to achieve a quality result. In this article you will be given detailed instructions on how to drill the concrete with your own hands.

Tools
To drill a reinforced concrete surface, it is necessary to use specialized tools - in this case it will not work out a self-made tool.
Depending on your preferences and the diameter of the hole, you can use a punch drill or a small-sized electric punch. The first option has less power, but at the same time has less weight and convenient design. The perforator, respectively, has greater potential, weight and dimensions.
Note! Since the use of construction equipment is often one-time in nature - it is more rational to rent them. Considering the fact that their price is quite high, thus, you will save a considerable amount of funds.
In addition to the existing tools, you need to purchase special drill bits that allow you to work with a concrete surface. For the punch drill drills are selected with pobeditovym tip.
The perforator has its own set of percussion tips, which, in most cases, is quite enough. As additional components for the punch, you can also use a drill with a tip.

For the formation of holes with a diameter of 35 to 120 mm, nozzles-crowns are used, which have pointy teeth - with their help, grooves for sockets, switches, etc. are drilled. If you are thinking about whether it is possible to drill concrete with a screwdriver, then tungsten-carbide-coated crowns also exist for this purpose. However, please note that they are only suitable for units with a capacity of at least 1 kW.
Training
- Before drilling concrete, it is necessary to prepare the available tools.. First of all, the fixing cartridge is inspected for the presence of sand or other foreign elements - if any, they must be removed without fail. For this purpose, you can use a clean dry cloth;

- The drill should fit into the groove freely so that you can feel that it has entered all the way.. This is a prerequisite, failure to comply with which, may result in the tip becoming unusable. If we are talking about a punch drill, then it is necessary to clamp the drill as tightly as possible, in the punch clamp is carried out automatically;
- Before drilling the concrete ceiling, it is necessary to protect the face with a respirator or plastic visor.. When working with walls, the use of personal protective equipment is also desirable, although not so critical;
Drilling
The process of drilling concrete is not particularly difficult and consists only in the ability to work with the tool. When working with drills should combine the mode of the bump stop with drilling.
If you are using nozzles, crowns, the shock mode must be disabled. The only possible problem during this process will be reinforcement from the reinforcement cage, which may be in the way of the drill.

Before drilling the reinforcement in concrete, it is necessary to change the tip for working with concrete with a regular drill for metal and drill through the barrier. It is important to remember to turn off the screening mode before drilling the reinforcement in the concrete.
In addition to the above, there are also a number of useful tips that will help you achieve a quality result.
- Non-professional construction tools are not designed for long-term load, which should be considered when working with them. The case should not be overheated - on average, the period of continuous operation of the equipment is no more than 15 minutes, after which the mechanism requires cooling. The same 15 minutes of inactivity will be quite enough;
- When drilling, the drill gets very hot and when the critical temperature is reached, the tip starts to deform. To cool the drill bit, it is enough just to immerse the tip in water - the more often you carry out this operation, the less the consumable will wear out;

- If the drill is stuck, in no case should you try to turn it around increasing the speed - at best, you break the drill, and at worst you will ruin the tool itself. It is necessary to pull the tip out of the socket, charge a similar one and drill a hole next to it - only after that you can try to “release” the drill from captivity;
Diamond drilling
If you are thinking about how to drill a concrete slab through or create a hole of large diameter, then you can't do it by yourself. The most effective is the diamond drilling of holes in concrete and cutting of reinforced concrete with diamond circles, which are carried out with the help of specialized professional equipment.

The cost of installations is rather high, and it is irrational to purchase them for single use. It would be more reasonable to invite specialists who provide their services for a very reasonable price.

Properly selected equipment and professional approach will help you to cope even with such a difficult task as drilling concrete. More information on this topic can be obtained by viewing the video in this article.
