Drill cobalt fi 7,9 Inox
Drill 7,9 mm cobalt HSSE Inox. Modern 7,9 mm cylindrical twist drill bit designed for professional processing of extremely durable and hard-to-machine materials. The drills have 2 central blades, a tip angle of 118 degrees, spiral grooves for chip evacuation up the drilled hole, and strong ground cutting edges resistant to impact and lateral forces. An unquestionable advantage of the drill bits is that they are manufactured from special cobalt HSSE high-speed steel. It is a steel with 5% cobalt, which greatly enhances the ability to drill in harsh conditions. The drills can withstand high-speed drilling, during which high temperatures (up to 670 degrees) are generated. Even under such extreme conditions, the drill blades are not subject to fractures, cracks, chipping and other damage. The drills are suitable for machining alloy steels, stainless steel, heat-resistant steel, acid-resistant steel, cast iron and cast steel. Drill 7.9 mm cobalt is designed for drilling machines, milling machines and lathes as well as CNC machine tools
