How to drill a concrete wall

In the course of repair and finishing work, there is a need to drill the walls that are most often concrete. Let's say you need to suspend the locker, nourish the shelf, install a lamp or air conditioning, attach a metal profile or a plumbing device. Since concrete is a very solid material, it is seriously handling. In addition, when drilling drills can be stumbled upon the crushed stone present. Therefore, to do the hole in the concrete is not easy, you will have to work pretty.

Before drilling the concrete wall it is worth checking the surface on the subject that there are no water pipes and the communications of steam heating. For this use metal detector. With this device, it turns out to detect electrical cables passing near the place of work.

To trigger holes in concrete, it is customary to use a drill with a shock function or a perforator, and also practiced diamond drilling. If you need to do just a few holes, you can do the simple tool. But the usual drill is not suitable, it is recommended to prepare a drill on which the plate is attacked, made from the winning alloy. When the winning drill will be immersed in the wall, and the drill will stop knocking out, it should be started to break the material. For this take a piercer - metal pin, the diameter of which coincides with the size of the opening. Insert it into the hole, then you need to beat the hammer on it. So you should act until you crush the compacted areas. Trying a slightly pin, you can again use a drill, constantly scrolling the drill around your axis. It should not be heated, so it is recommended to make the drill with water. Repeat such actions until the required depth of the opening is achieved. Alternatively, universal with diamond spraying, which are installed on a regular drill can be used as an alternative to winning drills.

To make a large amount of work and drill holes in the bearing walls, you will need a perforator. A tool with a shock function is suitable if you deal with light concrete. In addition, you should consider the following: the drill can be done by a hole with a diameter of no more than 12 millimeters, the perforator will make large holes. The most positive moment is no need to use an optional tool, and you just need to switch modes. To drill a concrete, use the "Strike" function. And the perforator works faster. Remember that the SDS-Plus cartridge will be needed to work with concrete.

By means of diamond drilling with a special drill unit, it turns out to do a hole, which has a diameter of up to 40 centimeters. It almost does not form dust, and there will be no extra noise. Dust is washed away simultaneously with the cooling of the diamond crown - with automatic water supply. The holes are carried out neat, smooth, immediately with a ground surface from the inside. They can be done at any angle to the wall without the risk of cracking and chipping. In addition, this method is considered ideal if communications should be laid.

In most cases, concrete walls are derived by metal rods. In addition to the rods, there is a large aggregate in the concrete - rubble rock rocks of high density. In this case, you will have to drill a reinforced concrete, which is even greater strength than his relative. Therefore, it is recommended to ensure that the fittings wall is located in the wall. It is better that the metal detector has always been at hand. Having found a rod, try to do the hole away from them. But it can happen and so that you get straight in them - at the same time hear a kind of grinding. Winned drill on will not go. If fittings came across in the concrete wall - drill it using a metal drill. When entering the wire, the power tool may be unusable, and the risk of electric shock is worse, so when working should be extremely insensitive.

Often there is a need to drill the concrete wall in the conditions of finished repair. It is recommended to make a special device for collecting particles of material and dust - an envelope of cardboard. In addition, to prevent clogging room you need to use a vacuum cleaner. Its slit nozzle should be kept off opening during operation. It is necessary to withstand an angle of 45 degrees and turn on the vacuum cleaner to the maximum power. And even better to attract the assistant to keep the device.

Thus, if you choose the instrument to work with a concrete wall, you can do a hole without much difficulty, regardless of what rubble pieces or metal fittings can come across. Be sure to use while working with protective glasses to avoid getting into the eyes of concrete crumbs!
