VCMT110304 UE6020
Mitsubishi Materials | The Steel Turning Workhorse (CVD Coated)
Stable Performance in Carbon & Alloy Steels
The Mitsubishi VCMT110304 UE6020 is a 35° diamond CVD coated carbide insert designed for stability and long tool life in general steel turning. The UE6020 grade features a thick coating layer that provides superior wear resistance against plastic deformation and crater wear. With its 7° positive relief angle, this long-tail steel turning insert is the industry standard for CNC profiling and precision boring where high-speed efficiency meets tough cutting conditions.

UE6020 CVD Grade Advantage
The UE6020 grade is specifically optimized for P10-P30 steel applications. Utilizing a thick $TiCN + Al_2O_3 + TiN$ CVD coating, it provides high heat insulation, preventing the carbide substrate from softening during high-speed turning. This makes it the best steel insert for long continuous cuts in carbon and alloy steels where thermal stability is paramount.
Versatile Chip Control
The V-series diamond geometry is inherently sharp, making it ideal for precision boring and intricate profiling. By selecting the correct feed rate, the UE6020 grade maintains chip control through various depths of cut, ensuring that stringy steel chips do not wrap around the workpiece or the boring bar.
