TNMG160408-MA UE6020
Mitsubishi Materials | The Industry Standard for Versatile Steel Turning
The Mitsubishi TNMG160408-MA UE6020 is a highly versatile CVD coated carbide insert designed for stable to lightly interrupted turning of carbon and alloy steels. As a core long-tail precision tool, the UE6020 grade provides an optimized balance of crater wear resistance and edge toughness. The integrated MA chipbreaker is the definitive choice for medium cutting, ensuring excellent chip evacuation in standard CNC machining cycles.

UE6020 Material Grade
The UE6020 grade is Mitsubishi's premier choice for general steel turning. This CVD coated grade features a thick TiCN and Al2O3 layer that provides heat insulation and resists flank wear. It is exceptionally reliable for P25-P35 steel workpieces under varied cutting conditions.
MA Chipbreaker Logic
The MA chipbreaker is engineered for a "medium-range" depth of cut. Its geometry provides a sharp cutting action to reduce cutting forces while maintaining enough strength to prevent edge chipping, making it the most popular indexable turning insert geometry for general lathe work.
