RCMX1003MO US735
Mitsubishi Materials | The Specialist for Tough Stainless & Super Alloys
The Mitsubishi RCMX1003MO US735 is a high-toughness round turning insert designed for the most demanding stainless steel machining environments. Engineered with a specialized CVD coating, this 10mm round insert excels in profiling and copy turning where interrupted cutting or unstable setups lead to edge chipping in standard grades. It is a go-to solution for austenitic stainless steels (304/316) and heat-resistant super alloys.

US735 Toughness Advantage
The US735 grade features a high-TRS (Transverse Rupture Strength) substrate that acts as a shock absorber during heavy impacts. The CVD coating provides high resistance to notch wear and thermal cracking. This is arguably Mitsubishi's most reliable grade for low-to-medium speed unstable cutting in difficult-to-cut materials.
MO Profiling Chipbreaker
The MO chipbreaker provides a balanced cutting edge for general medium-cutting applications. On a round (R) insert, this indexable turning geometry maintains control over long, stringy stainless steel chips. Its design reduces cutting resistance while protecting the cutting edge during complex 3D profiling paths.
Recommended Cutting Parameters
