Drill cobalt fi 4,0 Inox
Drill 4,0 mm cobalt HSSE Inox. Modern cylindrical twist drill bit for stainless steel INOX and other hard and difficult-to-machine materials. The offered drill bits have a diameter of 4 mm, a tip angle of 118 degrees, strong cutting edges insensitive to impact and lateral forces, and special spiral grooves for chip removal up the drilled hole. Drill the 4.0 mm cobalt cutter is manufactured in accordance with the NWKa, DIN 338 dimensional standard from special high-speed steel enriched with cobalt (5%). Such a composition of steel improves the hardness of the drill bits and their durability against harsh cutting conditions, primarily against high temperatures (up to 670 degrees C) created when drilling at high speed. The drill blades are resistant to mechanical damage, which increases their service life. Our cylindrical drills are dedicated to large companies for professional processing of alloy steel, stainless steel, acid-resistant steel, heat-resistant steel, cast iron and cast steel. They are suitable for conventional and CNC machine tools.
