It is designed for drilling alloyed and unalloyed steels, grey cast iron, malleable cast iron, copper alloy, nickel silver, graphite, and sintered iron. The wide flutes and reinforced core allow for a drilling depth almost corresponding to the length of the twist, ensuring good chip removal. The point angle is 118°, and the surface is blued from 1.0 mm, with all dimensions starting from 4.0 mm featuring special grinding "AC". This industrial quality drill is suitable for NC machines, offering precision due to a modern grinding process and breakage resistance thanks to CNC-controlled heat treatment.
