RCMX1204MO UE6110
Mitsubishi Materials | Heavy-Duty Round Insert for Steel Profiling
The Mitsubishi RCMX1204MO UE6110 is a heavy-duty round turning insert engineered for maximum stability in steel machining. With a 12mm diameter, this R-type insert is the primary choice for profiling, copy turning, and high-volume metal removal. Utilizing the advanced UE6110 CVD coating, it provides an industry-leading balance of wear resistance and edge toughness, making it indispensable for stable CNC turning of carbon and alloy steels.
Technical Specifications
| ISO Designation | RCMX1204MO |
|---|---|
| ANSI Designation | RCMX 43 MO |
| Grade / Coating | UE6110 (CVD Al-Ti-N + Al2O3) |

UE6110 Grade Performance
The UE6110 grade is Mitsubishi's premium CVD coated carbide optimized for the P10-P20 range. It features a specialized thick Alumina layer that acts as a thermal shield, allowing for high-speed turning without compromising tool life. This grade is specifically designed to resist crater wear and plastic deformation when machining steel under continuous load.
MO Chipbreaker Design
The MO geometry is a medium-duty chipbreaker that provides a reinforced land for high-impact resistance. In indexable turning, the round RCMX shape allows for variable lead angles; the MO geometry ensures that chip control remains consistent whether you are performing a deep facing cut or a shallow profiling pass, reducing cutting resistance and harmonics.

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.
