DNMG150608-MA UE6020
High-Volume Steel Mastery | 6.35mm Thick Stability | MA Medium-Roughing Geometry
Engineered for Maximum Metal Removal Rate (MRR)
UE6020 Grade (Advanced CVD Coating): The UE6020 is Mitsubishi’s premier CVD grade for steel. It features a thick, multi-layered Al2O3 and TiCN coating that provides a superior heat shield. This allows for high-speed machining of Carbon Steel and Alloy Steels without the edge softening or cratering that limits PVD inserts.
MA Chipbreaker (The Multi-Purpose Standard): The MA geometry is designed for medium-range cutting. Its specialized rake angle and chip-pocket width ensure excellent chip breaking even in ductile "stringy" steels. This chipbreaker reduces cutting pressure, preventing vibration on longer workpieces.
06 Thickness & 0.8mm Radius: With a **6.35mm thickness**, this insert has the structural mass to handle heavy depths of cut. The **0.8mm (1/32") radius** provides a robust cutting edge that resists chipping during interrupted cuts while producing industrial-grade surface finishes.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness (S) | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150608-MA | 12.70 mm | 6.35 mm | 0.80 mm |
| Imperial | DNMG442-MA | 1/2" | 1/4" | 0.0315" (1/32") |
Recommended Cutting Parameters
*Optimized for steel turning. Use high-pressure coolant to maximize the life of the CVD coating.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Low Carbon Steel (1018) | 200 - 400 m/min | 0.15 - 0.45 mm/r | 1.00 - 4.50 mm |
| Alloy Steel (4140/4340) | 150 - 320 m/min | 0.15 - 0.40 mm/r | 1.00 - 4.00 mm |

UE6020 (The Tough Choice): Best for general-purpose turning in workshops where various steel grades are used. It handles slight interruptions and less-than-perfect setups much better than harder grades.
MC6015 (The High-Speed Expert): Use MC6015 for high-speed continuous finishing in stable setups. For rougher or unpredictable conditions, stick with the reliability of UE6020.

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.
