CNMG120408-MA UE6110
High-Velocity Steel Master | UE6110 CVD Grade | MA General Purpose Geometry
Optimized for High-Production Steel Turning
UE6110 Grade (The High-Speed Specialist): The UE6110 is a premium CVD-coated grade designed specifically for P-Class (Steel) materials. It features an advanced multi-layer coating with a thickened Al2O3 (Alumina) layer that acts as a superior heat shield. This allows for significantly higher cutting speeds than general-purpose grades, ensuring maximum crater wear resistance during long-run production.
MA Chipbreaker (Precision Flow): The MA geometry is a versatile medium-range chipbreaker. It is designed to provide stable chip control across varying feed rates. Its specialized rake angle reduces cutting forces, which is essential when machining at high velocities to prevent thermal overload on the cutting edge.
0.8mm (1/32") Universal Radius: The 08 radius provides the industry-standard balance between edge strength and surface finish. It is robust enough to handle the initial passes of medium roughing while remaining sharp enough to deliver excellent Ra values during finishing.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CNMG120408-MA | 12.7 mm | 4.76 mm | 0.80 mm |
| Imperial | CNMG432-MA | 1/2" | 3/16" | 0.0315" (1/32") |
High-Speed Cutting Parameters
*Designed for stable, continuous cutting. Use dry cutting or high-pressure coolant to maximize the CVD coating benefits.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Mild Steel (1018 / S235) | 250 - 500 m/min | 0.15 - 0.45 mm/r | 0.50 - 4.00 mm |
| High Alloy Steel (4140 / 4340) | 200 - 380 m/min | 0.12 - 0.35 mm/r | 0.50 - 3.50 mm |

UE6110 (Efficiency King): The go-to choice for high-speed automated production in stable conditions. It offers significantly longer tool life when running at 300+ m/min.
UE6020 (The Tough Alternative): If your setup is prone to vibration or you are dealing with heavily interrupted cuts (hex bars, holes, keyways), 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.
