The ground twist drill bit HSS allows for maximum precision in drilling metal. The exposed, cross-ground, self-centring tip with a 135-degree point angle enables active cutting and perfect centring without drill movement, ensuring exceptional precision. The cross-ground tip eliminates the need for pilot pre-drilling up to 10 mm. Precisely ground HSS steel (high-speed steel) allows for drilling at speeds up to 40% higher and with 50% less feed force compared to standard ground HSS drill bit edges. The drill bit is designed for drilling alloyed and unalloyed steel, cast steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals, and hard plastic. It is equipped with a cylindrical shank (shank equal to the drill bit diameter) and is intended for use with stationary drills and screwdrivers. The ground twist drill bit HSS complies with DIN 338 standard. Drill bit type N (point angle), with a 135-degree tip and diameter tolerance h8.
