Mitsubishi Materials | Precision Steel Finishing Cermet
Mirror Finish Precision with MV Control
The Mitsubishi TPMH090204-MV NX2525 is a high-performance Cermet turning insert designed for high-speed finishing of carbon and alloy steels. Unlike standard carbide, the NX2525 Cermet grade offers superior chemical stability, preventing the "welding" of work material to the edge. This long-tail precision tool, featuring the MV chipbreaker, is the ideal choice for CNC boring where dimensional accuracy and a high-gloss surface finish are paramount.

NX2525 Cermet Grade
NX2525 is a TiCN-based Cermet (Ceramic-Metal). It bridges the gap between the toughness of carbide and the heat resistance of ceramics. It is chemically inert to iron, which means zero Built-Up Edge (BUE) and a consistently high-quality surface finish on all steel workpiece materials.
MV "Multi-Value" Chipbreaker
The MV chipbreaker is designed for versatility. It excels in light-to-medium finishing, offering stable chip control even at fluctuating dephts of cut. Its geometry reduces cutting resistance, which is vital for preventing chatter in internal boring applications.
