NX2525 Cermet Grade
The NX2525 grade is a titanium-based cermet that combines the hardness of ceramics with the toughness of metal. It is designed for stable turning at high speeds, providing exceptional wear resistance and preventing material adhesion. This grade is the industry choice for precision turning of steels and cast irons where surface brightness is critical.
F Chipbreaker (Fine Machining)
The F chipbreaker is a specialized geometry for light finishing. It provides excellent chip evacuation even at very low depths of cut, preventing "bird's nesting." This indexable turning insert ensures a constant sharp edge for ultra-precise surface finishes.
