SCMT09T308 UE6110
Mitsubishi Materials | The Steel Turning Specialist (CVD Coated)
The Mitsubishi SCMT09T308 UE6110 is an industry-standard indexable turning insert designed for high-efficiency steel turning. Engineered with the high-performance UE6110 CVD coating, this insert excels in continuous high-speed cutting of carbon and alloy steels. The square 90° geometry with a 7° relief angle makes it a versatile tool for both external turning and internal boring, providing a balance of wear resistance and edge toughness for stable CNC machining.

UE6110 CVD Grade
The UE6110 grade is Mitsubishi's premium CVD solution for steel. It features a thick, smooth Al2O3 layer that provides exceptional thermal stability and resistance to crater wear. This is the first choice for high-speed continuous cutting where edge reliability and extended tool life are required in carbon and alloy steels.
Medium Cut Geometry
The 08 (0.8mm) radius provides a strong cutting edge suitable for medium-duty indexable turning. It allows for higher feed rates compared to the 0.4mm radius, while still achieving excellent surface finishes. The positive rake design ensures smooth chip flow and reduced power consumption.
Recommended Cutting Parameters

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.
