TPGX110302L NX2525
Mitsubishi Materials | High-Precision Steel Finishing Cermet (Left-Hand)
Advanced Cermet for Mirror Finishing
The Mitsubishi TPGX110302L NX2525 is a high-precision Left-Hand (L) Cermet turning insert. As a G-Class (Ground) insert, it is manufactured to much tighter tolerances than standard pressed inserts, ensuring exceptional repeatability. The NX2525 Cermet grade provides the ultimate chemical stability for high-speed finishing of steel, preventing built-up edge (BUE) and delivering a mirror surface finish that meets the highest industrial standards.

NX2525 Cermet Substrate
NX2525 is a TiCN-based Cermet grade. It provides a unique balance of hardness and chemical resistance. This long-tail precision insert thrives in high-temperature finishing because it does not chemically react with steel, ensuring a glossy surface even after long machining times.
Ground Finishing Geometry
The ground periphery of the TPGX geometry minimizes vibration in delicate CNC boring operations. With its sharp 0.2mm radius, it is perfect for finishing small bores and intricate profiles where dimensional accuracy is critical.
