Ø0.7 Inox cobalt drill bit for metal
0.7 mm cobalt drill bit for metal HSSE Inox. Professional straight-shank Inox cobalt drill bit manufactured to the NWKa, DIN 338 dimensional standard. Designed for drilling through holes and blind holes in hard and difficult-to-machine materials such as unalloyed steels, metals, nonferrous metals, metal alloys, and plastics. The drills feature 2 central cutting edges and special flutes for chip evacuation up the hole. The point angle is 118°. These 0.7 cobalt drill bit for metal have a solid construction, made entirely from high-grade high-speed steel with added cobalt (5%) – HSSE. The addition of this element makes the NWKa drills available in our store highly productive and resistant to demanding operating conditions. Above all, these drills resist all types of mechanical damage (breakage, cracking, chipping, edge fracture), as well as cutting edge wear caused by the very high temperatures generated during high-speed drilling. These straight-shank drills are suitable for conventional drilling machines, lathes, and milling machines, as well as CNC machine tools.
