TPGX090202L NX2525
Mitsubishi Materials | Precision Steel Finishing Cermet (Left-Hand)
Super-Precision Mirror Finishing
The Mitsubishi TPGX090202L NX2525 is a Left-Hand (L) high-precision G-Class (Ground) Cermet insert. Specifically engineered for the high-speed finishing of carbon and alloy steels, the NX2525 Cermet grade provides exceptional chemical stability. By resisting "Built-Up Edge" (BUE) and oxidation, this long-tail precision tool is the premier choice for CNC boring and finishing where dimensional accuracy and a high-gloss surface finish are critical.

NX2525 Cermet Performance
NX2525 is Mitsubishi's premium Cermet grade. By utilizing TiCN-based materials, it achieves high hardness and chemical stability. This results in a sharp cutting edge that resists oxidation at high speeds, providing the "gloss" finish required in high-end automotive and aerospace steel parts.
TPGX Precision Ground
The "G" in TPGX signifies a periphery ground tolerance. Unlike M-class pressed inserts, the TPGX series is ground to strict specifications, ensuring minimal run-out in boring bar applications and perfectly consistent chip control.
