Mitsubishi Materials | High-Speed Cermet Finishing Specialist
Mirror-Like Precision with Cermet Technology
The Mitsubishi TPMN110304 NX2525 is a high-performance Cermet turning insert designed for the ultimate surface finish. The NX2525 grade combines the hardness of ceramics with the toughness of metal, making it exceptionally resistant to oxidation and built-up edge. This uncoated cermet specialist is the industry standard for high-gloss finishing of carbon and alloy steels, ensuring your final parts meet mirror-quality specs and tight tolerances.

NX2525 Cermet Advantage
The NX2525 Cermet grade is specifically optimized for steel finishing. Because Cermet has a low affinity for steel, it effectively prevents material welding (BUE) on the cutting edge. This leads to a significantly longer tool life during high-speed finishing operations and provides a vastly superior surface luster compared to standard tungsten carbide.
TPMN Flat-Top Precision
The TPMN series features a flat-top (no chipbreaker) design. This is often preferred in stable finishing environments where the material creates manageable chips naturally at high speeds. It offers a strong, sharp edge for precision boring and light finishing passes where consistency is the top priority.
