HSS Cobalt spiral drill bit is characterized by a very long service life when drilling in stainless steel. The 5% cobalt and ground HSS (high-speed steel) alloy ensures longer service life, excellent surface finish quality, greater wear resistance, and protection against overheating. Two cutting edges and two flutes allow for fast chip removal and extend the drill bit's service life. The drill bit is designed for drilling alloyed and unalloyed steel, stainless steel, cast iron, cast steel, and steel resistant to acid and high temperatures. The drill bit is designed for drilling alloyed and unalloyed steel, stainless steel, cast iron, cast steel, and steel resistant to acid and high temperatures. 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 HSS Cobalt spiral drill bit is manufactured according to DIN 338 standard. Type N drill bit (point angle) with a 135-degree tip and h8 diameter tolerance. Active cutting and excellent centering without the drill bit slipping on the surface thanks to the cross-ground tip.
