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.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
