TCMT16T304 NX2525
Mitsubishi Materials | The Standard for Mirror-Finish Steel Turning
The Mitsubishi TCMT16T304 NX2525 is a high-performance turning cermet insert engineered for precision finishing operations. Utilizing the NX2525 uncoated cermet grade, this tool provides exceptional chemical stability and resistance to built-up edge (BUE), which is critical for achieving a mirror-like surface finish on carbon and alloy steels. As a preferred long-tail precision tool, it ensures high dimensional accuracy and long tool life in high-speed applications.

NX2525 Cermet Grade
The NX2525 grade is a specialized cermet (Ceramic-Metal composite). Unlike standard carbide, it has a low affinity for metal workpieces, which virtually eliminates built-up edge. It is designed specifically for high-speed finishing of steel, offering superior wear resistance and maintaining a sharp cutting edge for extended periods.
Optimized Chip Control
The TCMT geometry features a 7° positive relief angle, reducing cutting force and heat generation. This indexable finishing insert is optimized for light depths of cut, ensuring excellent chip evacuation and preventing workpiece scratching in long-run CNC production.
Recommended Cutting Data
