Steel Machining Powerhouse | UE6020 CVD Coating | MV Versatile Geometry
Engineered for High-Speed Steel Turning
UE6020 Grade (The Steel Expert): The UE6020 is a premier CVD-coated carbide grade specifically for P-Class (Steel) materials. It features a multi-layered coating that provides a hard exterior for wear resistance and a tough interior to prevent fracture. It excels in stable, continuous cutting where high surface speeds are required to meet production targets.
MV Chipbreaker (Medium-V Finishing): The MV geometry is Mitsubishi's most balanced chipbreaker. It provides a sharp cutting action to reduce heat buildup while maintaining enough edge strength for semi-finishing tasks. It effectively controls chips across a broad range of speeds, preventing "bird-nesting" during automated cycles.
0.4mm Radius (Industry Standard): The "04" (1/64") radius is the universal choice for finishing. It offers the ideal balance between surface roughness ($Ra$) and edge durability, making it perfect for the majority of precision steel turning applications.

Shop 07 Series HoldersPro-Tip: UE6020 vs. VP15TF
UE6020 (CVD): Best for high-speed efficiency in carbon steel. Choose this for long-run production where you need the tool to last as long as possible under heat.
VP15TF (PVD): Switch to VP15TF if you are machining small diameter parts or if you are switching between steel and stainless steel on the same machine.
