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.
