Mitsubishi Materials | The Mirror-Finish Specialist (Left-Hand)
Precision Engineering Overview
The Mitsubishi TPGH110304L-FS NX2525 is a high-performance Left-Hand (L) cermet insert designed for precision finishing. Featuring the advanced NX2525 cermet grade, it offers superior resistance to chemical wear and oxidation compared to standard carbide. The FS chipbreaker is specifically engineered for ultra-fine finishing, making this a critical long-tail precision tool for CNC machining of carbon and alloy steels where a reflective surface luster is required.

NX2525 Cermet Grade
The NX2525 grade is a specialized titanium-cermet material. Cermets offer lower affinity for steel workpieces than carbide, which prevents built-up edge (BUE). This makes it the premier choice for lathe turning operations that require mirror-like surface finishes and high dimensional stability.
FS Super-Finish Breaker
The FS chipbreaker features an exceptionally sharp rake and high positive geometry. It is specifically designed to control chips at light depths of cut, ensuring chip evacuation is clean and does not mar the workpiece surface during CNC boring.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed per Rev ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Carbon & Alloy Steel | 150 - 350 m/min | 0.05 - 0.15 mm/rev | 0.1 - 0.8 mm |
| Stainless Steel (Finishing) | 100 - 220 m/min | 0.05 - 0.12 mm/rev | 0.1 - 0.6 mm |
REQUIRED LEFT-HAND HOLDERS
This is a Left-Hand (L) insert. Use standard STFPL 11 or STGPL 11 boring bars and holders.

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.
