US735 Tough-Grade Carbide
The US735 grade is Mitsubishi's premier choice for indexable turning inserts facing interrupted cuts in stainless steel. Its unique CVD coating prevents thermal cracking and provides extreme chemical stability against built-up edge (BUE), making it a long-tail industrial tool essential for difficult austenitic alloys.
ES Precision Chipbreaker
The ES chipbreaker is specialized for fine finishing. It features an exceptionally sharp rake angle that reduces cutting resistance and heat generation. This ensures excellent chip control even at shallow depths of cut, preventing surface damage and vibration.
Recommended Cutting Parameters
