UE6020 Material Grade
The UE6020 grade is Mitsubishi's benchmark for stable steel turning. It features a robust CVD coating that provides excellent heat insulation and resistance to edge chipping. This indexable turning insert is specifically tuned for P25-P35 steel groups, offering reliable performance even in less-than-perfect setups.
MA Chipbreaker Logic
The MA chipbreaker is a medium-cutting geometry that balances edge sharpness with structural strength. It prevents chip welding and nesting, making it suitable for both carbon steels and mild steels. Its design is ideal for mid-range depths of cut and feed rates.
