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.
Recommended Cutting Parameters

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
