Ø12.8 Inox cobalt drill bit for metal
12.8 mm metal drill bit Inox cobalt right-hand twist drill with specially ground edges and a 118° point angle. The drill has a smooth straight shank and is manufactured to dimensional standard NWKa, DIN 338. Straight shank drills of this type are solid, meaning they are made entirely from special high-grade HSSE high-speed steel. This exceptional tool steel improves cutting performance, increases machining productivity (reducing machining time), enables highly accurate drilling, and, above all, increases tool resistance to demanding operating conditions. Our 12.8 cobalt metal drill bits are designed for professional machining on drilling machines, milling machines, and lathes, as well as computer-controlled CNC machine tools. They can drill holes in materials in classes P1.2 – P1.3 – metals, unalloyed steels, plastics, and nonferrous metals.
