Ø6.5 Inox cobalt drill bit for metal
6.5 mm cobalt drill bit for metal HSSE Inox. Modern straight-shank twist drill with a diameter of 6.5 mm, designed for professional drilling of through holes and blind holes in very hard materials. These drills comply with the NWKa, DIN 338 dimensional standard and are made from special HSS-E high-speed steel, in which cobalt is a key constituent (5%). Cobalt drills are significantly more resistant to severe operating conditions, particularly the high temperatures generated during high-speed drilling. In addition, cobalt steel drills enable highly productive drilling, allowing more efficient use of available workstations. Designed for machining alloy steel, stainless steel, acid-resistant steel, heat-resistant steel, cast steel, and cast iron. 6.5 mm cobalt drill bit for metal is suitable for drilling machines, milling machines, lathes, and computer numerically controlled machine tools.
