RCMT0602MO US735
Mitsubishi Materials | Stainless Steel Specialist Round Insert
The Mitsubishi RCMT0602MO US735 is a high-toughness round turning insert engineered specifically for machining stainless steel. Round inserts are the premier choice for copy turning and profiling due to their incredible edge strength. Utilizing the specialized US735 PVD coating, this insert excels in difficult-to-cut materials and interrupted cutting conditions where thermal cracking and chipping are common risks in CNC turning.

US735 PVD Advantage
The US735 grade is a dedicated PVD coated carbide designed for the M-class (Stainless Steel) applications. It features a high-toughness substrate that absorbs impact during interrupted cuts. The TiAlN coating layer provides excellent lubrication to prevent built-up edge (BUE), which is the primary cause of poor surface finish when turning gummy stainless materials.
MO Geometry Security
The MO chipbreaker is a medium-duty geometry that emphasizes edge security. Because round inserts offer a variable lead angle, the MO geometry ensures that cutting resistance is distributed evenly along the edge. This makes it a highly reliable indexable turning solution for roughing to medium profiling of stainless pipes, shafts, and valves.

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.
