TPGH160304L-FS NX2525
Mitsubishi Materials | The Standard for Mirror-Finish Cermet (Left-Hand)
Precision Finishing Overview
The Mitsubishi TPGH160304L-FS NX2525 is a high-precision Left-Hand (L) cermet turning insert engineered for super-finishing applications. Featuring the titanium-based NX2525 grade, it provides unmatched chemical stability and resistance to built-up edge (BUE). The FS chipbreaker is specifically designed 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 Advantage
The NX2525 grade is a titanium-based cermet. Unlike tungsten carbide, it has a low affinity for ferrous metals, preventing built-up edge (BUE). This is essential for lathe turning operations requiring mirror-like surface quality and high-speed efficiency.
FS "Super-Finish" Breaker
The FS chipbreaker features an exceptionally sharp rake and high positive geometry. It provides excellent chip evacuation even at extremely low feed rates, ensuring a clean surface on internal CNC 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.
