High-Speed Steel Specialist | UE6110 Hardened CVD | 55° Diamond Profile
Engineered for High-Volume Steel Production
UE6110 Grade (High-Speed CVD): The UE6110 is Mitsubishi’s premier grade for high-speed turning of steel (P05–P20). It features a specialized thick-layer TiCN + Al2O3 coating with improved smooth-surface technology. This reduces friction and prevents "built-up edge" (BUE) even at elevated temperatures, allowing for significantly higher cutting speeds than standard carbide grades.
DCMT Geometry (Positive Rake): The 55-degree diamond shape with a 7-degree relief angle is the industry standard for precision profiling. Its positive rake geometry ensures a clean shearing action, reducing the power consumption of your machine and protecting the workpiece from heat-induced stress.
0.4mm Precision Radius: The "04" (1/64") radius is the choice for high-accuracy finishing. It provides the ideal balance of edge sharpness and strength, allowing for a high-quality surface finish while maintaining dimensional stability over long production runs.

Recommended Machining Parameters
*UE6110 is designed for high-speed efficiency. Do not run at low speeds to avoid premature wear.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (S45C/1045) | 200 - 400 m/min | 0.05 - 0.20 mm/r | 0.20 - 1.50 mm |
| Alloy Steel (SCM440/4140) | 180 - 350 m/min | 0.05 - 0.15 mm/r | 0.20 - 1.20 mm |

Shop 07 Series HoldersPro-Tip: UE6110 vs. UE6020
UE6110 (High Speed): Choose this for stable, continuous cutting at high RPMs. It offers the highest wear resistance for high-speed finishing.
UE6020 (General Purpose): Choose this if your setup is less rigid or if you have light interrupted cuts. UE6020 has slightly better toughness to handle mechanical shocks.
