VCMT080202-MV NX2525
Mitsubishi Materials | Ultra-Precision Mirror Finishing Specialist
Extreme Precision for Fine Steel Profiling
The Mitsubishi VCMT080202-MV NX2525 is a 35° diamond Cermet turning insert engineered for high-speed, light-duty finishing. The NX2525 Cermet grade offers superior resistance to built-up edge (BUE) and oxidation, ensuring your workpiece achieves a brilliant, mirror-like texture. Featuring a sharp 0.2mm corner radius and a 7° relief angle, this long-tail finishing insert is the professional choice for intricate external profiles and high-tolerance internal boring in carbon and alloy steels.

NX2525 Cermet Advantage
Cermet technology combines ceramic hardness with metallic toughness. The NX2525 grade is non-coated, providing a sharper cutting edge than PVD/CVD inserts. It is chemically inert to steel, meaning it won't react with the workpiece even at high temperatures, effectively preventing built-up edge and ensuring dimensional stability across long production cycles.
MV Chipbreaker for Fine Finish
The MV (Medium-V) chipbreaker is specialized for low depth-of-cut finishing. When combined with a 0.2mm radius, it ensures that even the thinnest chips are curled and broken away from the surface. This is critical for CNC boring applications where chip wrapping can destroy a finished internal surface.
