Mitsubishi Materials | The Mirror-Finish Cermet Authority
The Mitsubishi TNMG160408 NX2525 is a high-performance cermet turning insert engineered for precision finishing operations. Utilizing the advanced NX2525 titanium-based cermet grade, this tool excels in high-speed finishing of carbon and alloy steels. It provides superior chemical stability and resistance to oxidation, making it the premier long-tail precision tool for achieving a mirror-like surface finish that traditional carbide grades cannot match.

NX2525 Cermet Grade
The NX2525 grade is a composite material of ceramic and metal (Cermet). It provides superior resistance to built-up edge (BUE) compared to standard carbide. Because cermet has a low affinity for steel, this indexable turning insert maintains a sharp cutting edge for longer, ensuring mirror-finish results and tight dimensional tolerances.
TNMG General Geometry
The TNMG 6-edged design offers exceptional cost-performance for CNC finishing. The 0.8mm radius provides increased edge strength over the 0.4mm version, allowing for slightly higher feed rates while maintaining a high surface finish quality. This is the "workhorse" geometry for stable finishing passes.
Recommended Cutting Parameters
