RCMT0803MO UE6110
Mitsubishi Materials | Precision Round Insert for Steel Profiling
The Mitsubishi RCMT0803MO UE6110 is a specialized round turning insert engineered for high-performance steel machining. Its circular geometry provides the strongest possible cutting edge for profiling, copy turning, and heavy-duty roughing. Featuring the advanced UE6110 CVD coating, this insert is the industrial standard for stable cutting conditions, offering superior resistance to heat and wear during continuous CNC turning operations.

UE6110 CVD Technology
The UE6110 grade is Mitsubishi's premium choice for turning carbon and alloy steels. This CVD (Chemical Vapor Deposition) coating features a thick layer of Alumina ($Al_2O_3$), which provides a thermal barrier to protect the carbide substrate. It is optimized for high-speed cutting, ensuring the edge remains sharp even when the cutting resistance generates significant heat.
MO Profiling Geometry
The MO chipbreaker is designed for medium-duty applications. Round inserts inherently lack a traditional nose radius, meaning the entire edge can be utilized. This geometry provides exceptional indexable turning stability, allowing for a higher surface finish quality and greater versatility in 3D profile milling and turning.

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.
