NX2525 Cermet Grade
The NX2525 Cermet is a titanium-based material that provides high hardness and excellent thermal stability. It is specifically designed to prevent built-up edge (BUE), making it a critical long-tail precision tool for high-tolerance automotive and aerospace components requiring a glossy finish.
2G Chipbreaker Advantage
The 2G chipbreaker is a G-class finishing geometry. It features a specialized rake to maintain sharpness while ensuring consistent chip evacuation. This is the go-to geometry for lathe turning when the depth of cut is light but dimensional accuracy is non-negotiable.
Recommended Cutting Parameters
