Modern long drill bit for metal 6,7 with smooth cylindrical shank with a drilling diameter of 6,7 mm, is designed for professional processing of hard unalloyed steels, metals, non-ferrous metals, metal alloys and thermoplastics. The long metal drill 6,7 is made in accordance with the dimensional standard NWKb, DIN 340 from special molybdenum high-speed steel HSS (High Speed Steel). It is a steel distinguished by exceptional cutting properties. Compared with drill bits made of conventional tool steel, drill bits made of HSS are characterized by greater hardness, wear resistance, especially at the high temperatures created when drilling at high speeds. They are also characterized by resistance to mechanical damage such as fractures, cracks, chipping, dulling. The drills are designed for conventional drills, lathes, milling machines and computer numerical control machine tools - CNC.
