TNMG160408L-2G NX2525
Mitsubishi Materials | The Mirror-Finish Cermet Standard (Left-Hand)
Precision Engineering Overview
The Mitsubishi TNMG160408L-2G NX2525 represents the pinnacle of Cermet turning insert technology. Designed for Left-Hand (L) tool holders, this insert features the NX2525 grade—a titanium-based composite that excels in high-speed finishing and semi-finishing. As a specialized long-tail precision tool, it is engineered to deliver a superior surface luster on carbon and alloy steels, outperforming standard carbide in CNC machining environments where oxidation resistance is critical.

NX2525 Cermet Advantage
The NX2525 Cermet grade provides extreme thermal stability and lower affinity for ferrous metals compared to tungsten carbide. This eliminates built-up edge (BUE), making it the primary choice for lathe turning operations requiring mirror-like surface finishes and high-speed efficiency.
2G Chipbreaker Logic
The 2G chipbreaker is an G-class geometry specifically designed for light cutting loads. It maintains excellent chip evacuation even at shallow depths of cut, ensuring consistent dimensional accuracy and preventing surface scratching in CNC machining cycles.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed per Rev ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Carbon Steel (S45C) | 180 - 420 m/min | 0.10 - 0.35 mm/rev | 0.2 - 1.5 mm |
| Alloy Steel (SCM440) | 150 - 350 m/min | 0.08 - 0.30 mm/rev | 0.2 - 1.2 mm |
