Drilling holes in concrete: the necessary equipment and technology
Each master at least once faced withthe need for drilling concrete. Thus there are some questions, for example, what equipment and technologies to use at the same time. If you do not get right to this task, then the result may be a failure.
Choosing a tool for drilling concrete
If you want to drill holes inconcrete, for the beginning it is recommended to determine the tool. In this case, you can use one of the two options, the first is the percussive drill, the second is the perforator. The latter solution is preferable, since the main task of this tool is to punch holes in a stone or concrete. With this equipment, it is possible to obtain holes with a sufficiently impressive diameter, while even the best quality drill will not be able to make holes with a diameter exceeding 12 cm. However, if it is necessary to work with foam concrete, then in this case it is necessary to choose a drill, since the perforator just crash against the wall.
If you have to drillholes in the concrete, then you can not use an unstressed drill to work, it is not only useless, but it can also cause a tool breakdown. If you have to do only a few holes, then for want of a drill, a drill will do, too, whereas if you need to form a lot of holes, the rent or purchase of the corresponding equipment will be necessary. In this case, it's not just about saving time and effort, this requirement is due to the fact that devices of this type are not designed for high loads, and with mismanagement the equipment can become unusable. If you still need to use a drill, then you need to use a winning drill, designed to work on concrete. The tip should have a coating in the form of carbide spraying.
Diamond drills and other devices
Drilling holes in concrete can be carried outwith the help of ring drills, which have diamond spraying on top. They are designed to work in tandem with drilling rigs that are capable of making holes with a diameter of 25 centimeters. It should be taken into account that such devices are quite expensive, so it is useless to buy them for domestic use.
If during the repair there is a need to doplace for the socket or switch, then it is worth using crowns intended for working with concrete. Along the circumference of the working face and they have tapes made of hard metal alloys. Their diameter can vary from 35 to 120 millimeters. However, the most commonly used crowns, the size of which is 68 millimeters. This is due to the fact that this diameter is required for the installation of sockets.
If you want to drill holes in theconcrete, using the crown, it is necessary to turn off the perforator impact mode. As a rule, such devices are capable of forming holes, the depth of which is not more than 15 cm. If there is a need to go deeper into the wall to a more impressive thickness, an extension piece can be used. Such crowns can be used in tandem with a drill. Unlike the previous ones, such additions have a sputtering of carbide-tungsten alloy along the circumference. The advantage here is that if there is a need to make a hole in the concrete, which is tiled with a tile, then the nozzle need not be changed, it will be able to drill well not only the decorative layer, but the concrete itself. If you want to drill holes in concrete, equipment of the type described can be used with crowns, but the drill must not have a power above 1000 W.
If there is a puncher you are availableyou want to use with the drill, the diameter of the latter can vary from 4 to 80 millimeters. Quite often novice masters are wondering how to choose the right drill diameter.
Together with the puncher is recommended to purchaseset of drills for metal. However, quality kits have a very high cost, so the diameter should be the same as the dowel, which is supposed to be inserted into it. When buying such drills it is recommended to find out what tail they have - SDS + or SDS-max.
Features of drilling concrete
If you decide to drill holes inconcrete puncher, it is first necessary to check whether there are any contaminants in the cartridge. If they were detected, you must remove them with rags, otherwise you may experience some difficulties when working.
When inserting a drill in the cartridge, it is necessary to monitor theso that it is installed at a right angle, while the shank is mounted until it stops. The biggest problem that you can face when drilling, is the collision of the drill with metal fittings. As a rule, this happens when it is necessary to pierce the wall to a great depth. In this case, the armature must be traversed by the punch, only after this it is possible to continue the work. If the holes are made with a drill, then a metal drill will help with the job.
Recommendations of the master
If drilling holes in a concrete bitit is necessary to make a break for the same period every 15 minutes. This is due to the fact that a non-professional tool is not designed for a long load. During this time, not only the device will cool down, but also the consumable material. Before you continue working, you need to moisten the drill with water, this will extend the life of the drill.
When laser drilling of holes is performedconcrete, there may be a detachment of the wall sections from the back side. In this case, it is necessary to reduce the speed, then the process will be somewhat slower. Despite the fact that manipulation takes away a lot of time, the outside wall will remain untouched.
