Recommended Cutting Parameters
*Cermet (NX2525) performs best at high surface speeds. For optimal finishing, maintain a steady feed and avoid heavy interruptions.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Mild & Alloy Steel | 180 - 350 m/min | 0.05 - 0.15 mm/r | 0.1 - 1.0 mm |
| Stainless Steel | 120 - 220 m/min | 0.05 - 0.12 mm/r | 0.1 - 0.8 mm |
| Ductile Iron | 150 - 280 m/min | 0.08 - 0.18 mm/r | 0.2 - 1.2 mm |

Shop SCLC Boring BarsPro Tip: NX2525 vs VP15TF
NX2525 (Cermet): Your first choice for Precision Finishing. Cermet has a much lower affinity for steel than carbide, which prevents "built-up edge" (BUE) and results in a mirror finish. Best for continuous cuts.
VP15TF (PVD Carbide): Switch to VP15TF for interrupted cuts or medium roughing. Cermets are harder but more brittle; carbide provides the toughness needed for heavy shocks.

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.
