DNMG150408-MA UE6020
High-Speed Steel Specialist | CVD Multi-Layer Coating | MA Versatile Geometry
Optimized for Maximum Steel Productivity
UE6020 Grade (CVD Coating): The UE6020 is a specialized CVD-coated carbide grade designed for the high-speed turning of Carbon Steel and Alloy Steel. The thick multi-layer coating provides an excellent thermal barrier, preventing crater wear and plastic deformation even during continuous high-temperature cutting.
MA Chipbreaker (Medium Range Mastery): The MA geometry is Mitsubishi's most popular M-Class breaker. It is specifically designed to balance chip control and edge strength. It excels at medium depths of cut, ensuring chips are broken into small, manageable pieces to protect the workpiece and the machine.
0.8mm Radius (The Reliable Standard): The "08" (1/32") radius is the go-to choice for medium-duty turning. It provides a significantly stronger edge than the 0.4mm version, allowing for higher feed rates and better handling of slight interruptions or raw material scale.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150408-MA | 12.70 mm | 4.76 mm | 0.80 mm |
| Imperial | DNMG432-MA | 1/2" | 3/16" | 0.0315" (1/32") |
Recommended Machining Parameters
*The 0.8mm radius allows for robust feed rates. Optimize speed for the hardness of your steel grade.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Low Carbon Steel | 200 - 400 m/min | 0.15 - 0.45 mm/r | 1.00 - 4.50 mm |
| Alloy Steel (4140) | 150 - 300 m/min | 0.15 - 0.35 mm/r | 1.00 - 4.00 mm |

Shop DDJNR 15 HoldersPro-Tip: UE6020 vs. UE6110
UE6020 (The Tough Steel Grade): This is your go-to for general purpose steel turning. It has higher toughness than UE6110, making it much better for general machine shops where cutting conditions aren't always perfect.
UE6110 (The High Speed Grade): Use UE6110 only for high-speed, continuous turning of stable steel parts where heat is the primary enemy. For everything else, UE6020 is the more reliable choice.

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.
