Drill cobalt fi 1,4 Inox

Drill 1,4 mm cobalt HSSE Inox. Modern cobalt Inox drill bit, for all professional drilling work. Made according to the dimensional standard NWKa, DIN 338 from special high-speed cobalt steel HSSE. the 5% cobalt content improves the drill bit's hardness and wear resistance at temperatures up to 670 degrees C, which increases tool life and resistance to other harsh working conditions. The drills have a cylindrical shank, two central blades, a 118-degree blade angle and special grooves that guide the cut chips up the drilled hole. Drill 1.4 cobalt can be used for machining very hard materials (alloy steels, stainless steels, acid-resistant steels, heat-resistant steels, gray cast iron, ductile iron, cast steel). These drills are high-precision drills suitable for specialized precision machining using conventional drilling machines, lathes and milling machines, as well as modern computer-controlled numerical control machine tools. The blades of the drill bits are resistant to fractures, cracks, chipping, resulting in longer tool life.
