Mitsubishi Materials | High-Speed CVD Steel Specialist
Edge Strength for High-Volume Production
The Mitsubishi TPMH110308-MV UE6020 is a high-performance CVD coated carbide insert engineered for stable, high-speed turning of steel. Utilizing a multi-layer coating with a thick Alumina thermal shield, the UE6020 grade thrives in continuous cutting where heat management is critical. With a reinforced 0.8mm corner radius, this long-tail steel specialist tool offers maximum durability and longer tool life during CNC boring of Carbon Steels and Alloy Steels.

UE6020 CVD Layering
The UE6020 grade utilizes Chemical Vapor Deposition (CVD) to apply a thick Alumina shield. This coating is far more heat-resistant than PVD coatings, making it ideal for high-speed turning. It prevents plastic deformation of the cutting edge even during long continuous runs in Alloy Steels.
MV "Multi-Value" Chipbreaker
The MV chipbreaker is designed for finishing and semi-finishing. With the larger 0.8mm radius, it allows for a higher depth of cut (DOC) and feed rates while maintaining excellent chip evacuation, which is vital for preventing chip buildup in deep internal boring cycles.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Low Carbon Steel | 150 - 320 m/min | 0.10 - 0.25 mm/rev | 0.5 - 2.5 mm |
| Alloy Steel (Medium Hard) | 120 - 250 m/min | 0.08 - 0.20 mm/rev | 0.3 - 2.0 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.
