TMV Chipbreaker

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

TMV-WP

Double the feed rate and toollife & Reduce machining time by half.

Superior surface finish even under high feed conditions thanks to the wiper. Contributes to extended tool life by increasing feed.
