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

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
