Mitsubishi Materials | High-Durability Steel Turning Specialist
Extreme Edge Strength for Heavy Steel Profiling
The Mitsubishi VBMT160408-MV UE6020 is a 35° diamond CVD coated carbide insert designed for high-efficiency turning in carbon and alloy steels. The UE6020 grade is renowned for its thick, wear-resistant coating that thrives in high-heat, high-speed environments. Featuring the MV (Medium-V) chipbreaker and a reinforced 0.8mm corner radius, this long-tail steel turning insert is the ultimate choice for semi-finishing to medium roughing where tool life and edge stability are critical.

UE6020 CVD Coating Advantage
The UE6020 grade is optimized for the P10-P30 steel range. As a CVD (Chemical Vapor Deposition) grade, it features a thick layer of Alumina (Al₂O₃) that provides a massive thermal shield. This allows for higher cutting speeds and extended tool life in dry machining or high-temperature continuous cuts where PVD coatings would fail.
MV Medium-V Chipbreaker
The MV chipbreaker is Mitsubishi’s versatile workhorse for steel. It is specifically designed to manage chip flow during profiling. The 0.8mm radius combined with the MV geometry allows for higher feed rates without sacrificing chip control, making it perfect for efficient CNC steel 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.
