Drill cobalt fi 6,8 Inox under thread M8
Drill 6,8 mm cobalt HSSE Inox under M8 threader. Twist drill, with smooth cylindrical chuck, designed for professional drilling of through-holes and blind holes in high hardness materials. Drills of this type have strong cutting edges insensitive to impact and lateral forces, as well as special spiral grooves for fast chip removal up the drilled hole. They are made according to the NWKa, DIN 338 dimensional standard from special HSSE high-speed steel with 5% cobalt. Thanks to its properties, the drills are characterized by high resistance to changing working conditions, including thermal shock caused by high drilling speed. Cobalt 6.8 mm metal drill bits, allow high-performance and highly accurate drilling. Cobalt steel allows for much greater cutting capabilities even in very hard materials. Thanks to it, it is possible to machine hard-to-machine alloy steels, stainless steel, acid- and heat-resistant steel and even cast steel, cast iron and non-ferrous metals.
