High-Feed Finishing Specialist | NX2525 Cermet | 0.8mm Radius
Engineering Analysis
NX2525 Grade (TiCN Cermet): NX2525 is a non-coated Titanium Carbonitride-based cermet that represents the peak of Steel Surface Technology. Cermets are chemically inert to steel, meaning they resist the "welding" of chips to the tool edge. This prevents Built-Up Edge (BUE) and allows for ultra-high surface speeds while maintaining a consistent, jewelry-grade gloss.
0.8mm Radius (Productivity Edge): The larger 0.8mm radius makes the cutting edge significantly more robust than smaller versions. It is ideal for Semi-Finishing to Finishing transitions. The larger radius creates a broader contact area, allowing you to increase feed rates (mm/rev) while still achieving a smooth surface finish.
Metric vs. Imperial Specifications
| Unit System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT09T308 | 9.525 mm | 3.97 mm | 0.80 mm |
| Imperial | CCMT32.52 | 0.375" (3/8") | 0.156" (5/32") | 0.0315" (1/32") |
Recommended Cutting Parameters
*The 0.8mm radius provides the best results at slightly higher feed rates to ensure proper chip breaking.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (Finishing) | 150 - 350 m/min | 0.12 - 0.35 mm/r | 0.30 - 2.00 mm |
| Alloy Steel (SCM440) | 120 - 300 m/min | 0.10 - 0.28 mm/r | 0.30 - 1.50 mm |

NX2525 (Cermet): Specifically for Continuous Finishing. Achieve mirror finishes on steel that carbide can't match.
VP15TF / MP6015 (Carbide): Switch to these only for Stainless Steel or Heavy Interrupted Cuts. Cermet is more brittle; for roughing or shock-heavy applications, carbide is required.

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.
