Mitsubishi Materials | High-Gloss Cermet Precision Finishing
The Mitsubishi SNMG090304 NX2525 is a high-performance cermet turning insert designed for high-precision finishing. Utilizing the NX2525 cermet grade, it offers a perfect balance of toughness and wear resistance. Unlike standard carbide, this TiCN-based cermet has a low affinity for workpiece materials, virtually eliminating built-up edge (BUE) and producing a superior mirror surface finish on carbon and alloy steels.

NX2525 Cermet Grade
The NX2525 grade is a premium micro-grain cermet. It provides high thermal stability and chemical resistance, making it the industry standard for high-speed finishing of steel. It retains sharp cutting edges longer than coated carbide, ensuring dimensional accuracy throughout large production runs.
Standard Chipbreaker Geometry
The SNMG geometry provides a double-sided configuration for maximum economy. When paired with Mitsubishi's precision chip control, this insert excels at light finishing to medium cutting. It ensures consistent chip breaking at small depths of cut, which is essential for maintaining a high surface finish quality.
