VBMT110304-MV UE6020
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.
Recommended Cutting Parameters

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
