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.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
