NX2525 Titanium Cermet
The NX2525 grade is Mitsubishi’s premier micro-grain cermet. Unlike standard carbide, cermet has a low affinity for metal, which virtually eliminates the welding of work material to the edge. This makes it the top choice for precision machining where surface brightness and dimensional accuracy are critical.
1.6mm Radius Advantage
The larger 1.6mm nose radius on this indexable turning insert provides superior edge strength and allows for higher feed rates without sacrificing surface finish quality. It is ideal for larger workpieces or when high productivity in a finishing pass is required.
