NX2525 Cermet Grade
The NX2525 grade is a titanium-based cermet that provides high hardness and low chemical affinity with steel workpieces. Unlike carbide, it effectively prevents "smearing" at high speeds. This ensures that the indexable turning insert maintains its sharp edge, resulting in superior surface brightness and dimensional accuracy during high-speed finishing.
F Chipbreaker (Fine Machining)
The F chipbreaker is specifically optimized for precision turning at light depths of cut. Its rake geometry ensures excellent chip evacuation even in ductile materials, preventing workpiece scratching. This right-hand (R) configuration is perfect for standard OD turning and facing operations.
Recommended Cutting Data
