Mitsubishi Materials | High-Speed Steel Turning Specialist
The Standard for Stable Steel Production
The Mitsubishi VBMT110304-MV UE6020 is a 35° diamond CVD coated carbide insert engineered for high-efficiency turning in carbon and alloy steels. The UE6020 grade features a thick, heat-resistant coating layer that excels in high-speed continuous cutting. Equipped with the MV (Medium-V) chipbreaker and a 0.4mm corner radius, this long-tail steel turning insert provides a perfect balance of surface finish and edge durability for semi-finishing to light roughing operations.

UE6020 CVD Coating Advantage
The UE6020 grade utilizes a specialized CVD (Chemical Vapor Deposition) coating. This multi-layered coating is thicker than PVD alternatives, providing a powerful thermal barrier. It is designed to resist crater wear and plastic deformation at the high temperatures generated during high-speed steel turning ($P10-P30$ range), making it exceptionally durable for continuous cutting of mild and alloy steels.
MV Chipbreaker Performance
The MV (Medium-V) chipbreaker is Mitsubishi’s versatile workhorse. It features a geometry optimized for a medium depth of cut and feed range. This breaker is particularly effective at preventing chip entanglement in automated CNC production, maintaining a stable cutting force and ensuring excellent surface finish quality even during light roughing passes.
