ChipbreakerFor External turning ｜ Vibration / Oscillation & Conventional cutting Dual-Purpose Chipbreaker

Vibration / Oscillation cutting × Conventional cutting

Reliably long tool life and stable chip evacuation during vibration cutting

The development of a cutting tool that delivers maximum performance during vibration cutting utilization.
NTK provides the best choice and eliminates the guess work of selecting a tool.

Performance

Wiper insert has been added to the lineup for broader use
Dramatic reduction in cutting edge wear
Extended tool life even machining difficult-to cut materials
Stable chip removal with dramatic reduction in cutting edge wear
Stable chip formation during vibration cutting

Applications

Front turning operations on swiss cnc using vibration cutting function
