Twist drill HSS - Maykestag DIN338 RN 0.7 mm. This precision-ground twist drill features a short, right-hand cutting cylindrical shank and is designed for industrial quality drilling in alloyed and unalloyed steels, grey cast iron, malleable cast iron, copper alloy, nickel silver, graphite, and sintered iron. Key features include wide flutes and a reinforced core, allowing for a drilling depth nearly equal to the length of the twist and effective chip removal. The drill has a point angle of 118° and is blued from 1.0 mm, with all dimensions starting from 4.0 mm featuring special grinding "AC". It is suitable for NC machines and is precise due to a modern grinding process, with breakage resistance achieved through CNC-controlled heat treatment.
