Mitsubishi Materials | The Right-Hand Semi-Finishing Specialist
The Mitsubishi TNMG160408R-ES US735 is a high-performance Right-Hand (R) turning insert engineered for the challenging dynamics of stainless steel machining. Utilizing the legendary US735 toughness grade, this insert is designed to withstand mechanical shock in interrupted cuts. The ES chipbreaker is specifically optimized for semi-finishing, providing a sharp cutting edge that minimizes work-hardening and ensures stable chip control in gummy austenitic alloys.

US735 Grade Toughness
The US735 grade is Mitsubishi's specialized CVD turning insert material for P30-M35 applications. It is the premier choice for long-tail precision tools that require maximum resistance against thermal cracking and built-up edge (BUE) in tough stainless steel alloys.
ES Semi-Finish Geometry
The ES chipbreaker is designed for the transition between finishing and medium roughing. Its specialized rake angle lowers cutting forces and ensures that CNC machining cycles remain vibration-free while maintaining tight dimensional tolerances.
Recommended Cutting Parameters
