13.5 mm cobalt drill bit for metal HSSE Inox. Professional Inox cobalt twist drill bit, NWKa DIN 338, with a smooth straight shank for drilling cylindrical through holes and blind holes with a diameter of 13.5 mm. These drill bits have a solid construction and are made entirely from special high-alloy HSSE high-speed steel with 5% added cobalt. This exceptional tool steel has significantly better cutting properties than conventional tool steel. Above all 13.5 cobalt drill bit for metal made from cobalt steel stand out for their ability to provide highly efficient and accurate drilling.
Even when exposed to high temperatures (up to 670°), they maintain high cutting performance and do not suffer mechanical damage (breakage, cracking, dulling). This makes them recommended for professional machining of very hard materials, such as alloy steels, stainless steel, heat-resistant steel, acid-resistant steel, gray cast iron, and cast steel. They can be used on conventional drilling machines, milling machines, and lathes, as well as modern computer numerically controlled machine tools.
