The hardness of building materials is very varied. Drilling is not done by chip removal or wear of the material, but by disintegration. The drill bit for drilling masonry is identified by its tungsten carbide insert. It is associated with a perforator or a drill in percussion mode. To the rotary movement of the tool is added a striking action at very high frequency. In the percussion position, always work at low speed: otherwise the drill may warm up and lose its effectiveness. Note that marble, ceramic and various terracotta are hard materials that are pierced by simple rotation, without using percussion (such as plaster).
