Description

TNMG-M3 Indexable Carbide Inserts for Stainless Steel

The TNMG-M3 indexable insert is the universal solution for medium machining of stainless steel, offering robust design and high process reliability. With its modern AlTiSi nanocomposite PVD coating, it provides extreme hardness, high oxidation resistance, and thermal stability, ensuring consistently long tool life even under demanding cutting conditions. The low coefficient of friction reduces built-up edge formation and ensures clean, uniform surfaces.

Its stable 60° geometry makes the TNMG-M3 especially versatile and resilient. The M3 chipbreaker ensures secure chip breaking and reliable chip evacuation, even with deeper cuts. The tough substrate provides high fracture resistance and makes the insert robust against impact loads – ideal for both continuous and interrupted machining.

Thanks to consistent tool life, the TNMG-M3 reduces tool changes and contributes to significantly lower part costs. With its balanced combination of wear resistance, toughness, and geometry, it is the economical and process-secure choice for a wide range of stainless steel machining applications.
