Mitsubishi Materials | Large-Scale High-Speed Cermet Expert
The Mitsubishi TNMG220408 NX2525 is a heavy-duty cermet turning insert engineered for high-precision finishing on larger components. Utilizing the advanced NX2525 titanium-based cermet grade, this insert provides exceptional chemical stability and resistance to built-up edge (BUE). As a long-tail precision tool, it is the premier choice for achieving a mirror-like surface finish on carbon and alloy steels in large CNC lathes.

NX2525 Titanium Cermet
The NX2525 grade is a titanium-based cermet (ceramic-metal composite) that offers high chemical stability at high temperatures. Unlike standard tungsten carbide, this indexable turning insert does not easily weld to steel, preventing built-up edge and ensuring high-precision surface integrity and brightness.
TNMG Size 22 Geometry
The Size 22 (43x) platform is designed for larger tool holders, providing a massive heat sink and high structural rigidity. This allows for stable turning of larger diameters where vibration could otherwise ruin the surface finish. With 6 cutting edges, it offers superior cost-per-edge.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed per Rev ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Carbon Steel (S45C) | 180 - 380 m/min | 0.10 - 0.35 mm/rev | 0.3 - 2.5 mm |
| Alloy Steel (SCM) | 120 - 300 m/min | 0.10 - 0.30 mm/rev | 0.3 - 2.0 mm |
