TNMG160404R-2G NX2525
Mitsubishi Materials | High-Speed Cermet Finishing Specialist
The Mitsubishi TNMG160404R-2G NX2525 is a high-performance Cermet turning insert engineered for ultra-fine finishing. Unlike standard carbide, the NX2525 Cermet grade provides exceptional resistance to oxidation and built-up edge, making it the ideal long-tail precision tool for achieving mirror finishes. The 2G chipbreaker and Right-Hand (R) geometry are optimized for light depths of cut in CNC machining of carbon and alloy steels.

NX2525 Cermet Advantage
The NX2525 grade is a specialized titanium-based indexable turning insert material. It offers incredible thermal stability and lower affinity for steel, which prevents built-up edge (BUE). This grade is the industry standard for maintaining high dimensional accuracy over long production runs.
2G Fine-Finishing Breaker
The 2G chipbreaker is a precision geometry designed for very light finishing. It provides excellent chip control even at low depths of cut, ensuring that swarf is broken effectively to protect the workpiece surface finish during lathe turning operations.
Recommended Cutting Parameters
