Product Overview
The Mitsubishi TNMG160404L-2G NX2525 is a high-speed Cermet turning insert designed for Left-Hand (L) tool paths. Built with the advanced NX2525 grade, this titanium-based material offers unparalleled resistance to chemical wear and oxidation. As a premier long-tail precision tool, it is the industry standard for finishing steel components where a high-gloss surface and tight dimensional tolerances are required during CNC machining.

NX2525 Cermet Grade
The NX2525 grade is a specialized titanium-based composite. Cermet offers higher hardness at high temperatures compared to tungsten carbide, effectively eliminating built-up edge (BUE). This makes it perfect for achieving "ready-to-ship" surface finishes directly from the lathe turning process.
2G Finish Geometry
The 2G chipbreaker is a G-class finishing geometry optimized for light cutting loads. It provides stable chip evacuation even at shallow depths of cut ($a_p$), preventing "bird-nesting" and protecting the workpiece from scratches.
Recommended Cutting Parameters
