Recommended Cutting Parameters
*Cermet grades excel in high-speed, light-duty finishing. For NX2525, prioritize surface speed (Vc) to achieve the best finish.
| Workpiece Material | Speed (Vc) | Feed (fn) |
|---|---|---|
| Carbon & Alloy Steel | 150 - 300 m/min | 0.03 - 0.12 mm/rev |
| Stainless Steel (300/400) | 100 - 200 m/min | 0.05 - 0.10 mm/rev |
| Ductile Cast Iron | 120 - 250 m/min | 0.05 - 0.15 mm/rev |

Shop SCLC Tool HoldersCermet Tip: NX2525 vs VP15TF
NX2525 (Cermet): Choose this for Ultra-Precision Finishing. It provides higher thermal stability and lower chemical affinity to steel, meaning no built-up edge and a superior shine.
VP15TF (PVD Carbide): Switch to VP15TF if you are doing interrupted cuts or medium roughing. Cermets are brittle; for maximum edge life in continuous finishing, NX2525 is unbeatable.

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.
