High-Speed Steel Specialist | UE6110 CVD Grade | Precision Finishing 04 Radius
Optimized for High-Speed Productivity
UE6110 Grade (High-Velocity CVD): The UE6110 is Mitsubishi’s premium CVD-coated grade for P-Class (Steel). It is specifically hardened to withstand the extreme temperatures of high-speed turning. The advanced coating structure offers industry-leading crater wear resistance, making it the top choice for long-run production where maintaining a consistent finish at high speeds is required.
MA Chipbreaker (Precision Flow): The MA geometry is tailored for medium-to-finishing applications. It features a sharp rake angle that shears through steel cleanly, reducing heat generation at the tip. It ensures excellent chip evacuation even at the light depths of cut typically used in finishing passes.
0.4mm (1/64") Precision Radius: The small corner radius minimizes radial cutting pressure. This is essential for preventing chatter on long, slender workpieces or when using low-rigidity setups, allowing you to achieve Ra values that meet strict aerospace and automotive standards.

Shop DCLNR 12 HoldersPro-Tip: UE6110 vs. UE6020
UE6110 (High Speed): Use this when your primary goal is speed and tool life in stable, continuous cuts. It is a harder grade that loves heat.
UE6020 (General Purpose): Switch to UE6020 if you are experiencing edge chipping or if your setup involves interrupted cuts (like keyways or holes).
