Mitsubishi Materials | High-Speed Steel Turning & Medium Profiling
Heavy-Duty Profiling for Alloy & Carbon Steels
The Mitsubishi VBMT160404-MV UE6020 is a heavy-duty 35° diamond CVD coated carbide insert designed for high-efficiency turning. The 16mm edge length allows for deeper profiling passes compared to the 11mm series. Utilizing the UE6020 grade, this insert provides superior crater wear resistance during continuous high-speed steel machining. The MV chipbreaker ensures smooth chip evacuation, making it a premier long-tail CNC turning tool for both semi-finishing and medium roughing of various steel grades.

UE6020 CVD Steel Grade
The UE6020 grade is a CVD-coated workhorse designed for the P10-P30 steel group. It features a thick Alumina and Titanium Nitride layer that acts as a thermal shield. This allows for significantly higher cutting speeds ($v_c$) than PVD inserts while maintaining exceptional resistance to plastic deformation, especially during continuous dry machining.
MV Medium-V Chipbreaker
The MV chipbreaker is specifically designed for the "Medium" range of steel turning. Its unique wave-form rake profile breaks chips effectively at both light and heavy feed rates. This versatility makes it the best chipbreaker for profiling shafts or deep bores where chip accumulation could lead to tool failure.
Recommended Cutting Parameters

|---|---|---|---|
| Carbon Steel (A36/1045) | 150 - 320 m/min | 0.12 - 0.35 mm/rev | 0.5 - 3.5 mm |
| Alloy Steel (4140/4340) | 120 - 260 m/min | 0.10 - 0.30 mm/rev | 0.5 - 3.0 mm |

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.
