TPGX110304L NX2525
Mitsubishi Materials | Precision Steel Finishing Cermet (Left-Hand)
High-Velocity Mirror Finishing
The Mitsubishi TPGX110304L NX2525 is a high-precision Left-Hand (L) G-Class (Ground) Cermet insert. This long-tail precision tool is engineered for the high-speed finishing of carbon and alloy steels. The NX2525 Cermet grade provides exceptional chemical stability, effectively preventing "Built-Up Edge" (BUE) and oxidation, making it the premier choice for CNC boring and finishing where a high-gloss, mirror surface is the priority.

NX2525 Cermet Composition
NX2525 is a premium TiCN-based Cermet grade. Unlike standard carbide, Cermet has a very low affinity for iron. This means that even at high temperatures, the metal you are cutting won't "stick" to the insert, ensuring the sharp cutting edge remains clean for a superior surface finish.
TPGX Ground Geometry
The TPGX geometry is periphery ground (G-Tolerance). In boring bar applications, this ground finish ensures sub-micron accuracy and reduces tool pressure, allowing for stable machining even with small diameters or long overhangs.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Carbon Steel (Soft) | 150 - 350 m/min | 0.05 - 0.15 mm/rev | 0.1 - 0.8 mm |
| Alloy Steel (Hardened) | 120 - 280 m/min | 0.05 - 0.12 mm/rev | 0.1 - 0.6 mm |
COMPATIBLE LEFT-HAND HOLDERS
Designed for Left-Hand (L) tool paths. Pairs perfectly with S-STFPL 11 or S-STGPL 11 boring bars.
