Ø9.3 Inox cobalt drill bit for metal
9.3 mm cobalt drill bit for metal HSSE Inox. A modern straight-shank twist drill manufactured by grinding in accordance with the NWKa, DIN 338 dimensional standard. It features 2 central cutting edges, a 118° point angle, special flutes for rapid chip evacuation up the drilled hole, and exceptionally strong cutting edges resistant to impact and lateral forces. Our store offers straight-shank drill bits made of special HSSE cobalt high-speed steel. This steel delivers exceptionally high cutting performance.
Drill bits made from this steel withstand demanding operating conditions, especially the high temperatures (up to 670°C) generated during high-speed drilling. This enables high-performance drilling and better utilization of existing workstations. Cobalt steel drill bits also resist mechanical damage, offer durability, and withstand wear. They can be used for extended periods without replacement. Even after prolonged use, they retain their high cutting performance. 9.2 mm cobalt drill bits for metal are suitable for machining alloy steels, stainless steel, acid-resistant steel, heat-resistant steel, cast steel, cast iron, and other difficult-to-machine materials.
