US735 Grade Technology
The US735 grade is a specialized CVD carbide designed for P-M-K applications, specifically targeting M30-M40 stainless steel. It provides extreme resistance to built-up edge (BUE) and mechanical shocking, making it an elite long-tail precision tool for high-mix production.
ES Chipbreaker Design
The ES chipbreaker is Mitsubishi’s answer to precision machining in gummy alloys. Its high-rake edge reduces cutting force, while the specialized chip-pocket prevents bird-nesting in CNC machining environments, even at lower feed rates.
