NX2525 Cermet Advantage
The NX2525 grade is Mitsubishi's premier Cermet. Unlike standard carbide, cermet has a low affinity for metal-to-metal bonding, which effectively eliminates built-up edge (BUE). This property is crucial for lathe turning operations requiring tight dimensional tolerances and a high-gloss finish.
FS Chipbreaker Technology
The FS chipbreaker is a G-class super-finishing geometry. It features an ultra-sharp rake and positive angle to minimize cutting resistance. It excels at chip evacuation during very light depths of cut, ensuring no "birds-nesting" occurs in internal boring cycles.
