Mitsubishi Materials | The Specialist for High-Gloss Steel Finishing
Achieve Mirror-Quality Surfaces
The Mitsubishi TPMN110308 NX2525 is a high-speed Cermet turning insert engineered for precision finishing. The NX2525 grade is a non-coated cermet that provides exceptional chemical stability, effectively preventing Built-Up Edge (BUE). With its 0.8mm corner radius, this long-tail finishing tool provides a robust cutting edge capable of producing high-gloss surface finishes on carbon and alloy steels while maintaining strict dimensional tolerances during CNC boring.

NX2525 Micro-Grain Cermet
NX2525 is a cermet grade that bridges the gap between traditional carbide and ceramics. It features high resistance to plastic deformation and thermal shock. Because it contains metallic binders like nickel, it is tougher than pure ceramics but much harder than carbide, making it the perfect high-speed turning insert for steel finishing.
TPMN Flat-Top Advantage
The TPMN geometry features a flat-top face (no chipbreaker). This provides a stronger cutting edge for stable finishing passes. In high-speed steel turning, the chips naturally break or flow away easily; the absence of a chipbreaker reduces heat concentration at the tip, extending insert tool life.
