US735 Grade Performance
The US735 grade is Mitsubishi's premium PVD solution for stainless steel turning. It is designed with a specialized tough substrate that absorbs mechanical shock during interrupted cuts. The PVD coating acts as a thermal barrier, significantly reducing crater wear and built-up edges (BUE) in gummy materials like 304 or 316 stainless.
Heavy-Duty Geometry
Featuring a 0.8mm radius, this indexable turning insert offers extreme edge stability. The positive 7° relief angle reduces friction and heat generation, while the chipbreaker is optimized for medium-to-roughing passes, ensuring reliable chip evacuation in difficult-to-cut alloys.
