Drill 3,7 mm cobalt HSSE Inox. High-quality professional twist drill with smooth cylindrical chuck with a diameter of 3,7 mm. These types of drills are in accordance with the dimensional standard NWKa, DIN 338. The cylindrical drills offered in our store have 2 central blades, an apex angle of 118 degrees, chip grooves for the discharge of chips up the drilled creation, and specially ground cutting edges insensitive to impact and lateral forces. The drills are characterized by high cutting properties, and their blades are resistant to very harsh working conditions and resistant to fracture, cracking, chipping and other types of damage. This is due to the use of special cobalt HSSE high-speed steel with 5% cobalt in its production. This is a modern tool steel, thanks to which it is possible to increase cutting efficiency, thus reducing working time and making better use of the workstations you have. In addition, the drills allow more precise machining, and the holes made are of low roughness. The 3.7 mm cobalt metal drill bit is suitable for conventional drills, milling machines, lathes and CNC numerical control machine tools.
