Drill cobalt fi 3,4 Inox
Drill 3,4 mm cobalt HSSE Inox. Modern twist drill, cylindrical with strong cutting edges resistant to impact and lateral forces. Manufactured from modern HSSE high-speed steel, of which 5% cobalt is an important component. The drills comply with the NWKa, DIN 338 dimensional standard, with 2 central blades and special grooves for fast chip removal up the drilled hole. Cobalt steel drill bits are highly resistant to harsh cutting conditions and much more resistant than drill bits made from conventional tool steel. Their high cutting properties affect the ability to achieve high drilling performance and high cutting precision at the same time. The holes produced are of low roughness and are axial along their entire length. High resistance to damage makes them suitable for machining such materials as alloy steels, stainless steel, acid-resistant steel, heat-resistant steel, ductile iron, gray iron, cast steel, non-ferrous metals. The 3.4 mm cobalt metal drills are designed for conventional and CNC machine tools.
