TPMH160304-MV UE6020
Mitsubishi Materials | Heavy-Duty CVD Coated Steel Turning
Engineered for High-Speed Large Diameter Boring
The Mitsubishi TPMH160304-MV UE6020 is a robust CVD coated carbide insert designed for high-efficiency turning of large steel workpieces. Utilizing the UE6020 grade, which features a thick Alumina thermal shield, it thrives in continuous high-speed cuts that would degrade standard tools. This long-tail steel turning specialist utilizes the MV chipbreaker to ensure consistent chip fragmentation in CNC boring of Carbon Steels and Alloy Steels.

CVD Grade UE6020 Technology
The UE6020 grade is the champion of high-productivity steel turning. By using Chemical Vapor Deposition (CVD), Mitsubishi applies a thick, layered coating that acts as a massive heat barrier. This enables significantly higher surface speeds ($v_c$) while preventing crater wear and plastic deformation in Carbon and Alloy Steels.
MV "Multi-Value" Chipbreaker
The MV chipbreaker is a medium-finishing geometry designed for versatility. On the larger TPMH16 platform, it provides stable chip control across varying depths of cut. This is critical for preventing chip entanglement in large-scale boring operations and maintaining a superior workpiece finish.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Low Carbon Steel | 150 - 320 m/min | 0.05 - 0.20 mm/rev | 0.3 - 2.5 mm |
| Alloy Steel (Medium Hard) | 120 - 280 m/min | 0.05 - 0.15 mm/rev | 0.2 - 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.
