CCGT03S102L-F NX2525
Swiss-Type Specialist | NX2525 Cermet | Precision Mirror Finish
Material & Geometry Analysis
NX2525 Grade (TiCN Cermet): Unlike standard carbide, the NX2525 is a Titanium Carbonitride-based cermet. It features high chemical stability and exceptional resistance to oxidation. This allows for higher cutting speeds and prevents metal-to-metal welding, resulting in a high-gloss surface on steel components that often eliminates the need for grinding.
L-F Chipbreaker (Left-Hand Finishing): This is a precision-ground, sharp-edge geometry designed for ultra-light depths of cut. The L-F breaker is specifically tuned for Swiss-style lathes and small boring bars, ensuring that chips are curled and evacuated even at feed rates as low as 0.02 mm/rev.
Model & Dimensional Comparison
| Unit System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCGT03S102L-F | 3.97 mm | 1.98 mm | 0.20 mm |
| Imperial | CCGT1.21.20.5L-F | 0.156" (5/32") | 0.078" (5/64") | 0.0079" |
Recommended Cutting Parameters
*Cermets perform best in continuous cutting. Ensure consistent coolant flow or dry air blast to avoid thermal shock.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon & Alloy Steel | 150 - 300 m/min | 0.02 - 0.10 mm/r | 0.05 - 0.50 mm |
| Stainless Steel (400 Series) | 120 - 220 m/min | 0.03 - 0.08 mm/r | 0.05 - 0.35 mm |

Shop Small-Series HoldersPro-Tip: NX2525 vs VP15TF
NX2525 (Cermet): First choice for Mirror Finishing in steel. It maintains a sharper edge for a longer duration at high speeds, but it is brittle.
VP15TF (PVD Carbide): Switch to VP15TF if you encounter interrupted cuts or are machining gummy 300-series Stainless Steel. Carbide offers the impact resistance that Cermet lacks.

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.
