Ø8 Inox cobalt drill bit for metal
8 mm cobalt drill bit for metal HSSE Inox. High-quality twist drill with a smooth straight shank and a diameter of 8.0 mm for drilling holes in very hard materials such as alloy steel, stainless steel, acid-resistant steel, heat-resistant steel, cast steel, cast iron, and nonferrous metals. The drills are manufactured to the NWKa, DIN 338 dimensional standard from modern high-grade HSSE high-speed steel. This steel contains 5% cobalt, which significantly improves the drills' cutting performance. This steel allows the drills to withstand the high temperatures generated during high-speed drilling. As a result, machining time is reduced and available workstations are used more efficiently. In addition, the drills resist all types of mechanical damage, extending their service life. 8.0mm cobalt metal drill bit is suitable for modern CNC machine tools, as well as conventional drilling machines, lathes, and milling machines.
