Mitsubishi Materials | Large-Scale High-Gloss Finishing Specialist
Industrial Precision for Mirror-Finish Boring
The Mitsubishi TPMN160304 NX2525 is a premium Cermet turning insert designed for high-speed finishing operations. The NX2525 grade is a specialized ceramic-metal composite that offers superior resistance to Built-Up Edge (BUE) and plastic deformation. With its 16mm edge length and 0.4mm radius, this long-tail precision insert is the ultimate choice for achieving mirror-like surface lusters in large-scale CNC boring of carbon and alloy steels.

NX2525 Cermet Technology
The NX2525 Cermet grade provides a unique combination of high wear resistance and superior chemical stability. Because Cermet has a much lower affinity for steel than tungsten carbide, it virtually eliminates chip welding. This allows the tool to maintain a sharp edge for longer durations, resulting in the signature high-gloss finish Mitsubishi is known for.
TPMN Flat-Top Geometry
The TPMN geometry is a flat-top design without a molded chipbreaker. This provides maximum edge strength and a sharp cutting action. It is specifically intended for stable finishing passes where the feed rate is low and the focus is purely on surface quality and dimensional accuracy in steel turning.
Recommended Cutting Parameters
