CNMG120412-MA UE6110
High-Efficiency Rougher | UE6110 CVD Grade | 1.2mm Reinforced Corner
Engineered for Maximum Speed & Feed
UE6110 Grade (High-Temperature CVD): The UE6110 is Mitsubishi’s premium hard-coated grade for P-Class (Steel). It is specifically designed to perform at higher cutting speeds than general-purpose grades. The thickened Al2O3 layer provides an elite thermal barrier, protecting the carbide substrate from the extreme heat generated during high-speed roughing of carbon and alloy steels.
MA Chipbreaker (Medium-Heavy Range): The MA geometry is a robust general-purpose design. On this 12-radius platform, it excels at controlling thick, heavy chips. Its reinforced land area prevents the edge from "cratering" under the high pressure of aggressive metal removal, while the rake angle is optimized to keep cutting forces manageable.
1.2mm (3/64") Radius Edge: The large corner radius is built for Impact and Heat Dissipation. It allows for a higher feed rate per revolution and provides significantly more edge strength than a standard 0.8mm radius, making it perfect for roughing through scale or uneven surfaces at high speed.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CNMG120412-MA | 12.7 mm | 4.76 mm | 1.20 mm |
| Imperial | CNMG433-MA | 1/2" | 3/16" | 0.0472" (3/64") |
High-Speed Roughing Parameters
*The UE6110 grade loves speed. Maintain high Surface Meters per Minute (Vc) for best chip control.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Low Carbon Steel (1020 / S235) | 250 - 480 m/min | 0.25 - 0.55 mm/r | 1.20 - 5.00 mm |
| Alloy Steel (4140 / 4340) | 180 - 350 m/min | 0.20 - 0.45 mm/r | 1.20 - 4.50 mm |
Compatible Tool Holders
Maximum rigidity is essential for 1.2mm radius roughing. Fits DCLNR/L 12 series holders:

UE6110 (The Efficiency King): Choose this when your setup is stable and you want to increase cycle time. It offers superior wear resistance in high-heat continuous turning.
UE6020 (The Tough Tank): If you are experiencing edge chipping due to heavy vibrations or interrupted cuts (holes/slots), switch to UE6020 for its higher impact toughness.

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.
