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.

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 |

Shop DCLNR 12 HoldersPro-Tip: UE6110 vs. UE6020
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.
