NX2525: Mirror-Finish Grade
NX2525 is a premium uncoated cermet grade. Cermets are chemically stable at high speeds, which prevents the built-up edge (BUE) that often ruins precision parts. This grade provides the highest gloss levels on the workpiece, making it the top choice for steel finishing turning where visual quality is critical.
F-Breaker: Micro-Finishing Geometry
The F-breaker is specifically designed for small depths of cut ($a_p$). It effectively breaks chips even at ultra-low feed rates, preventing "bird-nesting" on small bore turning or delicate outer diameters. The "L" indicates the Left-hand orientation for specific tool holder setups.
