Mitsubishi Materials | The Mirror-Finish Specialist (Left-Hand)
The Mitsubishi TPGH110302L-FS NX2525 is a premium Left-Hand (L) cermet turning insert engineered for super-finishing and precision boring. Utilizing the titanium-based NX2525 Cermet grade, this tool provides unmatched chemical stability and resistance to oxidation. As a specialized long-tail precision tool, it is the industry choice for achieving mirror finishes on carbon and alloy steels in CNC machining environments where surface integrity is paramount.

NX2525 Cermet Advantage
The NX2525 grade is Mitsubishi's premier Cermet. Unlike standard carbide, cermet has a low affinity for metal-to-metal bonding, which effectively eliminates built-up edge (BUE). This property is crucial for lathe turning operations requiring tight dimensional tolerances and a high-gloss finish.
FS Chipbreaker Technology
The FS chipbreaker is a G-class super-finishing geometry. It features an ultra-sharp rake and positive angle to minimize cutting resistance. It excels at chip evacuation during very light depths of cut, ensuring no "birds-nesting" occurs in internal boring cycles.

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.
