Drill cobalt fi 20 Inox

Drill 20 mm cobalt HSSE Inox. Twist drill bit with smooth cylindrical chuck for drilling holes of 20 mm section. It is produced in accordance with the NWKa, DIN 338 standard. It is characterized by high cutting properties, which is a direct result of its production from modern HSSE high-speed steel, the composition of which is additionally enriched with 5% cobalt content. This element increases the hardness of the drill bit and its durability. It allows high-performance drilling, which results in shorter machining time and more rational use of owned workstations. In addition, it should be added that the cylindrical drills we offer are characterized by high resistance to harsh working conditions and a lower risk of blade damage. They are suitable for processing hard materials such as alloy steels, acid-resistant steel, heat-resistant steel, stainless steel, cast steel, cast iron, non-ferrous metals. Cobalt 20 mm metal drills are recommended for conventional machine tools (drills, lathes, milling machines) and CNC numerical control machine tools.
