NX2525 Cermet Technology
The NX2525 Cermet grade is a titanium-based material that offers exceptional resistance to oxidation and built-up edge (BUE). Cermet stays sharper longer than carbide at high speeds, making it the premier choice for lathe turning operations that require "as-polished" surface quality.
FS Chipbreaker Geometry
The FS chipbreaker is an ultra-sharp geometry optimized for super-finishing. It provides excellent chip control even at extremely low feed rates and shallow depths of cut, essential for high-precision components and light boring applications.
Recommended Cutting Parameters
| Workpiece Material | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Carbon/Alloy Steel | 150 - 300 m/min | 0.03 - 0.12 mm/rev | 0.05 - 0.5 mm |
COMPATIBLE BORING BARS
This Left-Hand (L) insert requires Left-Hand boring bars or turning holders, typically STFPL or STGPL series.

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.
