Carbide drills and cutters

The drills and cutters are completely made of heat-resistant and extremely hard metal. This consists of 90 - 95 % tungsten carbide and 5 - 10 % cobalt. The drills and cutters come from the professional metalworking industry and are usually not found in hobby workshops. In tools for do-it-yourselfers, usually only the drill tips are made of hard material and the rest of iron or HSS.
