Mitsubishi Materials | High-Performance CVD Coated Steel Turning
The Standard for High-Speed Steel Boring
The Mitsubishi TPMH090204-MV UE6020 is a high-speed CVD coated carbide insert engineered for excellence in steel machining. Featuring a thick Al2O3 (Alumina) layer, the UE6020 grade provides industry-leading thermal stability. Combined with the MV chipbreaker, it is the premier long-tail precision tool for finishing and light-medium CNC boring in Carbon Steels and Alloy Steels.

CVD Grade UE6020
UE6020 is a Chemical Vapor Deposition (CVD) grade designed for high surface speeds. Unlike PVD coatings, the thick layered Alumina structure in UE6020 acts as a massive heat barrier, protecting the carbide substrate from crater wear during prolonged steel turning operations. It is the gold standard for production-scale P-class machining.
MV Multi-Value Geometry
The MV chipbreaker features an optimized rake angle for medium-finishing. It effectively curls chips to prevent tool entanglement, especially critical in automated CNC lathe boring where manual chip clearing is not an option. It provides stable chip control across varying feed rates.

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.
