RCMT0803MO NX2525
Mitsubishi Materials | Cermet Technology for Mirror-Finish Profiling
The Mitsubishi RCMT0803MO NX2525 is a high-performance cermet turning insert designed for precision finishing and profiling of steel components. Unlike traditional carbide, the NX2525 cermet grade provides exceptional resistance to welding and oxidation. This round insert is the industry standard for achieving a high-gloss surface finish and maintaining strict dimensional tolerances during high-speed CNC turning.

NX2525 Cermet Advantage
The NX2525 grade is a TiCN-based cermet that provides superior wear resistance and thermal stability. Because it has a lower affinity for metal than carbide, it virtually eliminates built-up edge (BUE). This makes it the ultimate choice for finishing carbon steels and alloy steels where a "mirror-like" surface finish is required without the need for additional grinding.
MO Geometry Precision
The MO chipbreaker on a round insert offers a stable and secure cutting edge for copy turning. In cermet grades, this geometry is honed to perfection to handle cutting resistance while maintaining chip control. This indexable turning solution allows for smooth transition across varied profiles, ensuring consistent chip thickness even as the lead angle changes.
