Features

1. New HP chipbreaker For Finishing Hardened Steel
• By separating the chipbreaker from the cutting edge, the cutting force imposed on the cutting edge during machining is significantly reduced, thus providing long tool 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.

2. Chip control is stable for a long time
