US735 Grade Technology
The US735 grade is Mitsubishi's premium PVD coated carbide solution for M-class stainless steel. It features a specialized tough substrate paired with a PVD coating that prevents work hardening and notch wear. This makes it ideal for difficult-to-cut alloys where thermal stability and edge toughness are paramount.
Positive Chipbreaker Effect
The TCMT geometry provides a positive rake angle that lowers cutting force. This indexable turning insert is equipped with a chipbreaker optimized for medium-to-light finishing, ensuring excellent chip evacuation in gummy stainless steels, which prevents tool damage and surface marring.
