VBMT160408-MV UE6020
Mitsubishi Materials | High-Durability Steel Turning Specialist
Extreme Edge Strength for Heavy Steel Profiling
The Mitsubishi VBMT160408-MV UE6020 is a 35° diamond CVD coated carbide insert designed for high-efficiency turning in carbon and alloy steels. The UE6020 grade is renowned for its thick, wear-resistant coating that thrives in high-heat, high-speed environments. Featuring the MV (Medium-V) chipbreaker and a reinforced 0.8mm corner radius, this long-tail steel turning insert is the ultimate choice for semi-finishing to medium roughing where tool life and edge stability are critical.

UE6020 CVD Coating Advantage
The UE6020 grade is optimized for the P10-P30 steel range. As a CVD (Chemical Vapor Deposition) grade, it features a thick layer of Alumina (Al₂O₃) that provides a massive thermal shield. This allows for higher cutting speeds and extended tool life in dry machining or high-temperature continuous cuts where PVD coatings would fail.
MV Medium-V Chipbreaker
The MV chipbreaker is Mitsubishi’s versatile workhorse for steel. It is specifically designed to manage chip flow during profiling. The 0.8mm radius combined with the MV geometry allows for higher feed rates without sacrificing chip control, making it perfect for efficient CNC steel turning.
