If there is a need to drill a hole in reinforced concrete, it is likely to get into the reinforcement. The drill used in concrete work is not suitable for steel. Therefore, it should be changed to the one intended for metal work.
Most often, the need to drill rebar arises when forming a hole in concrete or sawing part of a reinforced concrete slab. This is required when arranging the inlet to the second floor, attic or basement.
What will be needed in order to drill fittings?
In order to make a hole in a steel bar, you need a drill or hammer, which works in the "drill" mode. In addition to this tool, a metal drill will be required. In work it is recommended to use drills of the P18 or P6M5 brand. These products are coated with a titanium-containing alloy, therefore, have high strength. Usually the color of such drills is black or dark gray, so they are quite simple to distinguish from the mass of other similar products. The tip of the drill must be sharpened: it will be much easier to make a hole in the reinforcement. Professionals do not recommend using HSS brand drills in their work, as they are much weaker in strength.
