VCMT160404 UE6020
Mitsubishi Materials | Durable CVD Coated Steel Turning Master
Heavy-Duty Precision for Steel Profiling
The Mitsubishi VCMT160404 UE6020 is a 35° diamond CVD coated carbide insert engineered for reliability in carbon and alloy steel applications. The UE6020 grade features a specialized multi-layer coating that offers exceptional resistance to heat and plastic deformation. With a large 16mm edge for stability and a 0.4mm corner radius for fine detail, this long-tail steel turning insert is the professional choice for CNC profiling and high-precision boring where durability is a non-negotiable requirement.

UE6020 CVD Grade Technology
The UE6020 grade is Mitsubishi's premium CVD solution for the P10-P30 steel range. It features a triple-layer coating ($TiCN + Al_2O_3 + TiN$) that creates a thermal barrier, allowing for higher cutting speeds while protecting the edge from cratering. It is the best steel turning insert for workshops running long production cycles on carbon and alloy steels.
35° Diamond Geometry
The VCMT geometry provides a 7° positive clearance which is essential for internal boring and deep profiling where back-clearance is limited. The 16mm size provides the bulk and rigidity needed to handle higher depths of cut compared to smaller 11mm variants, making it highly effective for larger workpieces on CNC lathes.
Recommended Cutting Parameters
