DNMG110404-MA UE6110
High-Velocity Steel Turning | UE6110 CVD Grade | MA Precision Geometry
Engineered for High-Cycle Efficiency
UE6110 Grade (High-Temp CVD Coating): The UE6110 is Mitsubishi’s premium grade for high-speed continuous turning of steel. It features an ultra-thick $Al_2O_3$ (Aluminum Oxide) coating layer that provides world-class thermal insulation. This allows the tool to maintain a sharp edge even at surface speeds exceeding 300 m/min, specifically in Carbon Steel and Alloy Steels.
MA Chipbreaker (Multi-Application Precision): The MA geometry is the versatile standard for medium-to-finishing cuts. It features a specialized rake face that stabilizes chip flow at high velocities. This design effectively breaks chips even in low-carbon "gummy" steels, preventing surface marring and tangled nests.
0.4mm Radius (The Finishing Detail): The "04" (1/64") radius is the choice for precision. It generates lower radial forces than larger radii, making it ideal for maintaining tight tolerances on slender parts and achieving a high-definition surface finish.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG110404-MA | 9.525 mm | 4.76 mm | 0.40 mm |
| Imperial | DNMG331-MA | 3/8" | 3/16" | 0.0157" (1/64") |
Recommended Machining Parameters
*UE6110 thrives at higher speeds. Avoid using at very low RPM to prevent built-up edge.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045/S45C) | 250 - 450 m/min | 0.08 - 0.25 mm/r | 0.30 - 2.50 mm |
| Alloy Steel (4140/SCM440) | 200 - 380 m/min | 0.08 - 0.20 mm/r | 0.30 - 2.00 mm |
Pro-Tip: UE6110 vs. UE6020
UE6110 (Speed Specialist): The absolute best choice for stable, high-speed continuous turning. It provides 30-50% longer tool life in clean steels compared to general grades.
UE6020 (The Generalist): Choose UE6020 if you have interrupted cuts, vibration, or unstable setups. UE6110 is harder but more brittle; it thrives on speed and stability.

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.
