High speed steel cutting tools are suitable for most general applications and have better overall wear resistance. Black oxides increase lubricity and form small pits on the tool surface, which are used to fix the coolant near the cutting edge. The round handle allows for more tool clamping systems to be used together. When running in a counterclockwise direction, the spiral groove tool will discharge the chips upwards from the incision, reducing blockage. Suitable for production, maintenance, or portable drilling work.
