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.

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.
