New HP ChipbreakerFor Finishing Hardened Steel
By separating the chipbreaker from thecutting edge, the cutting force imposedon the cutting edge during machining issignificantly reduced, thus providing longtool life.
The cutting edge preparation is designed to ensure easy cutting at low cutting forces, while maintaining close tolerances with no deviations.
The HP style chipbreaker, combined with built-in wipers, yields excellent surface quality and good chip control.
