For Front Turning | Vibration / Oscillation & Conventional cutting Dual-Purpose Chipbreaker

Advanced Chipbreaker Design for Reliable Performance & Longer Tool Life
Home / Front & Back Turning / TMV Chipbreaker

Reliably long tool life and stable chip evacuation during vibration cutting

Designed for maximum performance in vibration cutting, the TMV cutting tool ensures stability and efficiency. Its optimized geometry minimizes cutting resistance and enhances chip control, making it the ideal choice for challenging applications.
Features
  • 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
Application

Front turning operations on swiss cnc using vibration cutting function
