Mitsubishi Materials | High-Speed Steel Turning Specialist
The Standard for Stable Steel Production
The Mitsubishi VBMT110304-MV UE6020 is a 35° diamond CVD coated carbide insert engineered for high-efficiency turning in carbon and alloy steels. The UE6020 grade features a thick, heat-resistant coating layer that excels in high-speed continuous cutting. Equipped with the MV (Medium-V) chipbreaker and a 0.4mm corner radius, this long-tail steel turning insert provides a perfect balance of surface finish and edge durability for semi-finishing to light roughing operations.

UE6020 CVD Coating Advantage
The UE6020 grade utilizes a specialized CVD (Chemical Vapor Deposition) coating. This multi-layered coating is thicker than PVD alternatives, providing a powerful thermal barrier. It is designed to resist crater wear and plastic deformation at the high temperatures generated during high-speed steel turning ($P10-P30$ range), making it exceptionally durable for continuous cutting of mild and alloy steels.
MV Chipbreaker Performance
The MV (Medium-V) chipbreaker is Mitsubishi’s versatile workhorse. It features a geometry optimized for a medium depth of cut and feed range. This breaker is particularly effective at preventing chip entanglement in automated CNC production, maintaining a stable cutting force and ensuring excellent surface finish quality even during light roughing passes.

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.
