TNMG160408-MA US735
Mitsubishi Materials | The Tough Stainless Steel Specialist
The Mitsubishi TNMG160408-MA US735 is a high-toughness CVD coated carbide insert engineered for the complexities of stainless steel turning. Utilizing the legendary US735 grade, this insert excels in preventing thermal cracking and adhesive wear, making it the top choice for interrupted cuts. Combined with the versatile MA chipbreaker, it provides stable chip control and reduces built-up edge (BUE) during medium-range cutting operations.

US735 Grade Technology
The US735 grade is a specialized CVD coated carbide designed for ISO M30-M40 applications. It is engineered with a high-strength substrate that resists impact, making this indexable turning insert perfect for machining austenitic stainless steels (304, 316) even in unstable turning conditions.
MA Medium Chipbreaker
The MA chipbreaker is designed for medium-duty cutting. Its unique geometry provides a sharp cutting action while maintaining edge strength, effectively preventing work hardening of the workpiece. This ensures smooth chip evacuation and high precision machining results.
Recommended Cutting Parameters

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.
