Ø11.5 Inox cobalt drill bit for metal
11.5 mm cobalt drill bit for metal HSSE Inox. Advanced Inox cobalt twist drill bit with a straight shank, manufactured to the NWKa DIN 338 dimensional standard. Recommended for drilling holes in very hard and difficult-to-machine materials such as alloy steels, stainless steel, acid-resistant steel, heat-resistant steel, gray and ductile cast iron, nonferrous metals, and cast steel. The superior cutting properties of the drill bits result from the use of special HSSE high-speed steel with 5% added cobalt. This exceptional tool steel is used to manufacture cutting tools of the highest grade. Its properties significantly improve cutting efficiency, reduce machining time, increase tool resistance to demanding operating conditions, and improve cutting edge resistance to potential mechanical damage. Our 11.5 cobalt drill bit for metal with NWKa straight shanks resist breakage, cracking, chipping, and even dulling. Suitable for all mechanical and computer numerically controlled machine tools.
