Grade: NX2525 Cermet Excellence
The NX2525 grade is a premium uncoated cermet. Cermets (Ceramic + Metal) are chemically inert, meaning they do not react with steel at high temperatures. This prevents crater wear and adhesion, allowing the TCMT090204 to maintain its sharp edge. It is the premier choice for high-speed finishing where a glossy surface finish is mandatory.
Chipbreaker: General Purpose Finishing
Designed for light depths of cut, this geometry provides excellent chip evacuation. It prevents "bird-nesting" during long finishing passes on small diameters, ensuring your workpiece remains scratch-free and your CNC cycle remains uninterrupted.
