Applications & Features
Applications
Features
HS chipbreaker
Optimized chipbreaker design for excellent chip control during hard turning at aggressive conditions
- Designed for high feed machining.
- Provides excellent chip control for a wide range of D.O.C. and feed rates.
- Edge preparation is designed to prevent catastrophic failure.
HP chipbreaker
Designed for finish machining of hardened parts with close tolerances
- Optimized chipbreaker geometry significantly reduces cutting force imposed on the cutting edge, ensuring long tool life.
- The edge preparation is designed to generate low cutting force, providing chatter-free machining and close tolerances.
- The built-in wiper yields excellent surface quality and good chip control.
HF and HM chipbreakers
- Suited for hard turning applications requiring great D.O.C. such as carburized layer removal.
- Effective chip breaking is possible for a wide range of hard materials.
- BXA20 and BXM20 CBN grade inserts are available for aggressive cutting depths.
