CPMH090308-MV UE6020
High-Strength Steel Specialist | UE6020 CVD Barrier | MV Reliable Chipbreaking
Engineered for Performance and Durability
UE6020 Grade (Steel Specialist CVD): The UE6020 is Mitsubishi's premier grade for P-Class (Steel). It is designed to thrive in the medium-to-low cutting speed range, where thermal stability and edge toughness are paramount. The thick CVD coating provides a sacrificial barrier against crater wear, ensuring the carbide substrate remains intact during heavy roughing or interrupted cuts.
MV Chipbreaker (Wide-Range Medium Cut): The MV chipbreaker is the "universal" choice for positive inserts. It is specifically designed to handle "voluminous" chips. By forcing the chip into a tight radius, the MV geometry ensures that long, stringy chips—common in carbon steels—break into manageable pieces, protecting the tool holder and the workpiece.
0.8mm (1/32") High-Strength Radius: The 08 radius is the "productivity" radius. It allows for significantly higher feed rates compared to the 04 version, making it ideal for removing material quickly while maintaining a robust cutting edge that resists chipping in unstable setups.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CPMH090308-MV | 9.525 mm | 3.18 mm | 0.80 mm |
| Imperial | CPMH322-MV | 3/8" | 1/8" | 0.0315" (1/32") |
Heavy Steel Cutting Parameters
*The 0.8mm radius thrives at higher feed rates. Use high-volume coolant to prevent heat buildup on the tool flank.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Low Carbon Steel (1018/1045) | 130 - 260 m/min | 0.12 - 0.35 mm/r | 0.50 - 3.00 mm |
| High Alloy Steel (4140/4340) | 100 - 190 m/min | 0.10 - 0.28 mm/r | 0.40 - 2.50 mm |

Shop 09 Series HoldersPro-Tip: UE6020 vs. NX2525
UE6020 (The Impact Choice): Use this as your primary grade for steel roughing and interrupted cuts where the tool must endure mechanical shock.
NX2525 (The Finish Choice): Switch to NX2525 Cermet only when you transition to high-speed finishing and require a superior surface luster.

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.
