Twist drill HSS - Maykestag DIN338 RN 12.5 mm.

This precision-ground twist drill features a cylindrical shank and is designed for industrial quality drilling of 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 point angle is 118°, and the surface is blued from 1.0 mm. All dimensions start from 4.0 mm with special grinding "AC." This industrial quality drill is suitable for NC machines and is precise due to a modern grinding process, while also being breakage resistant due to CNC-controlled heat treatment.
