Ø7.6 Inox cobalt drill bit for metal
7.6 mm cobalt drill bit for metal HSSE Inox. A professional straight-shank twist drill with a diameter of 7.6 mm, designed for drilling through holes and blind holes in hard and difficult-to-machine materials. The drill bits are manufactured according to the NWKa, DIN 338 dimensional standard from special HSSE high-speed steel, with cobalt (5%) as a key constituent. This element significantly increases cutting performance and thus reduces machining time. In addition, the drill bits withstand demanding working conditions and resist all mechanical damage. The drill bits do not break, crack, chip, suffer edge breakage, or become dull. This allows them to be used for a very long time without replacement. 7.6 mm cobalt drill bits for metal are designed for professional use with drilling machines, milling machines, lathes, and computer numerical control machine tools.
