Mitsubishi Materials | Stainless Steel & Difficult-to-Cut Materials Specialist
The Mitsubishi TCMT110204 US735 is a high-performance PVD coated carbide insert designed for superior reliability in stainless steel turning. Utilizing the US735 grade, this tool is engineered to combat the challenges of built-up edges and thermal cracking. As a critical long-tail precision tool, it provides the necessary toughness for interrupted cuts in austenitic stainless steels like SUS304 and SUS316.

US735 Grade Technology
The US735 grade is Mitsubishi's premium PVD coated carbide solution for M-class stainless steel. It features a specialized tough substrate paired with a PVD coating that prevents work hardening and notch wear. This makes it ideal for difficult-to-cut alloys where thermal stability and edge toughness are paramount.
Positive Chipbreaker Effect
The TCMT geometry provides a positive rake angle that lowers cutting force. This indexable turning insert is equipped with a chipbreaker optimized for medium-to-light finishing, ensuring excellent chip evacuation in gummy stainless steels, which prevents tool damage and surface marring.

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.
