TCMT090204 US735
Mitsubishi Materials | Stainless Steel & Toughness Specialist
The Mitsubishi TCMT090204 US735 is a high-toughness PVD coated carbide insert specifically engineered for the challenging task of stainless steel turning. Utilizing the US735 grade, it excels in interrupted cutting and prevents the "built-up edge" (BUE) common in gummy materials. As a critical long-tail precision tool, it is the industry standard for reliable machining of 300-series stainless and heat-resistant alloys.

US735 PVD Grade
The US735 grade is Mitsubishi's premier PVD solution for stainless steel. It features a specialized coating that prevents welding between the tool and the workpiece. Its high toughness makes it significantly more resistant to breakage than CVD grades when facing interrupted turning conditions.
Positive Chipbreaker
The TCMT positive geometry combined with the US735 coating provides low cutting resistance. This prevents vibration and ensures smooth chip evacuation, which is critical for maintaining surface finish and tool life in difficult-to-cut alloys.

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.
