Ø6.4 Inox cobalt drill bit for metal
6.4 mm cobalt drill bit for metal HSSE Inox. High-quality twist drill with a smooth straight shank, designed for drilling through holes and blind holes in very hard materials. These drills feature 2 central cutting edges, a 118° point angle, special helical flutes for rapid chip evacuation up the hole, and ground cutting edges resistant to heavy impact and lateral forces. These drills are manufactured to the NWKa, DIN 338 standard from special HSSE cobalt high-speed steel. This steel offers very high cutting performance. Compared with drills made from conventional tool steel, the drills we offer provide significantly greater resistance to severe operating conditions and allow drilling at very high speeds, which generate high temperatures up to 670°C. Even under such extreme conditions, the drill cutting edges resist all types of mechanical damage, extending their service life. 6.4 mm cobalt drill bit for metal is recommended for all professionals.
