Drill cobalt fi 6,4 Inox
Drill 6,4 mm cobalt HSSE Inox. High-quality twist drill with smooth cylindrical chuck designed for drilling through-holes and blind holes in very hard materials. Drills of this type have 2 central blades, a tip angle of 118 degrees, special spiral grooves responsible for fast chip removal up the hole, as well as ground cutting edges insensitive to strong impacts and lateral forces. The drills in question are made according to the standards of NWKa, DIN 338 from special cobalt HSSE high-speed steel. It is a steel distinguished by very high cutting properties. Compared with drill bits made of conventional tool steel, the drill bits we offer are characterized by much higher resistance to harsh working conditions, allow drilling at very high speeds during which high temperatures are generated - up to 670 degrees C. Even in such extreme conditions, the drill blades are resistant to any mechanical damage, thus extending the period of their use. Drill 6,4 mm cobalt is recommended for all professionals.
