Ø5.2 Inox cobalt drill bit for metal
5.2 mm cobalt drill bit for metal HSSE Inox. Professional twist drill with ground cutting edges, a smooth straight shank, and a diameter of 5.2 mm. Designed for drilling through holes and blind holes in hard and difficult-to-machine materials. These drills comply with the NWKa, DIN 338 dimensional standard and are made from special high-grade HSSE high-speed steel with 5% cobalt. The addition of this element makes the drills highly productive and accurate. They enable machining of hard materials (alloy steels, stainless steel, acid-resistant steel, heat-resistant steel, cast iron, cast steel) while resisting mechanical damage such as breakage, cracking, edge chipping, spalling, and even dulling. Another advantage of our 5.2 cobalt metal drill bits is their high resistance to the high temperatures generated during high-speed drilling. These tools are recommended for professional machining in large metalworking facilities using conventional drilling machines, milling machines, and lathes, as well as computer numerically controlled machine tools – CNC.
