Drill cobalt fi 6,9 Inox
Drill 6,9 mm cobalt HSSE Inox. Cobalt twist drill bit is designed for drilling through-holes and blind holes with a cross section of 6.9 mm, in accordance with the dimensional standard NWKa, DIN 338. It has 2 central blades, a tip angle of 118 degrees, spiral grooves for chip removal up the hole, and ground cutting edges resistant to impact and lateral forces. The drills we offer are produced from modern molybdenum high-speed steel of HSSE grade, of which cobalt is an important component. The influence of this element is noticeable in the high resistance of the drill bits to harsh working conditions, and in particular to the high temperature generated when drilling at high speed. As a result, it is possible to reduce machining time and thus make better use of the workstations at hand. Cobalt 6.9 metal drills are resistant to fracture, chipping, breakage and other damage to the blades. They are suitable for machining alloy steels, stainless steel, acid-resistant steel, heat-resistant steel, cast steel and cast iron.
