Mitsubishi Materials | The Mirror-Finish Specialist (Left-Hand)
Precision Engineering Overview
The Mitsubishi TPGH110304L-FS NX2525 is a high-performance Left-Hand (L) cermet insert designed for precision finishing. Featuring the advanced NX2525 cermet grade, it offers superior resistance to chemical wear and oxidation compared to standard carbide. The FS chipbreaker is specifically engineered for ultra-fine finishing, making this a critical long-tail precision tool for CNC machining of carbon and alloy steels where a reflective surface luster is required.

NX2525 Cermet Grade
The NX2525 grade is a specialized titanium-cermet material. Cermets offer lower affinity for steel workpieces than carbide, which prevents built-up edge (BUE). This makes it the premier choice for lathe turning operations that require mirror-like surface finishes and high dimensional stability.
FS Super-Finish Breaker
The FS chipbreaker features an exceptionally sharp rake and high positive geometry. It is specifically designed to control chips at light depths of cut, ensuring chip evacuation is clean and does not mar the workpiece surface during CNC boring.
