Mitsubishi Materials | The Stainless Steel Specialist
Ultimate Toughness for Difficult Materials
The Mitsubishi TPMH090204-MV US735 is a high-performance PVD coated carbide insert engineered for excellence in stainless steel machining. The US735 grade features a high-toughness substrate that absorbs impact, making it the premier choice for interrupted cuts and gummy materials. Equipped with the MV chipbreaker, this long-tail precision insert excels at CNC boring and finishing by reducing cutting resistance and preventing work-hardening.

The US735 PVD Advantage
US735 is Mitsubishi's specialized Physical Vapor Deposition (PVD) grade for stainless steel. It is designed with a high-toughness carbide substrate that prevents fracturing during heavy vibration or interrupted cuts. The PVD coating layer provides exceptional resistance to Built-Up Edge (BUE), which is the primary cause of poor surface finish in stainless machining.
MV "Multi-Value" Chipbreaker
The MV chipbreaker geometry is optimized for finishing and light-medium turning. Its sharp cutting edge reduces cutting forces, thereby minimizing the heat generated in the workpiece. In boring operations, it effectively fragments tough stainless chips into small, manageable curls that are easily evacuated from the hole.

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.
