Ø6.2 Inox cobalt drill bit for metal
6.2 mm cobalt drill bit for metal HSSE Inox. Twist drill with a smooth straight shank for professional drilling of through holes and blind holes with a diameter of 6.2 mm. It is manufactured to the NWKa, DIN 338 dimensional standard from special HSSE cobalt high-speed steel with 5% cobalt. This steel gives the drill excellent durability when machining very hard materials and allows it to retain its properties even at the high temperatures generated during high-speed drilling. The addition of cobalt increases the drill's resistance to all types of mechanical damage, including breakage, cracking, and cutting-edge spalling. Its properties make the drill suitable for professional machining of hard components in large metalworking facilities and workshops. 6.2 mm cobalt drill bit for metal is suitable for conventional drilling machines, milling machines, lathes, and CNC machine tools.
