CCMT060204 NX2525
Mirror-Finish Specialist | TiCN Cermet Grade | 0.4mm Radius
Material & Geometry Analysis
NX2525 Grade (TiCN Cermet): This is a premium Titanium Carbonitride-based cermet. Unlike standard carbide, NX2525 possesses high chemical stability and thermal resistance. It is specifically designed to resist Built-Up Edge (BUE) and metal smearing. This allows for significantly higher cutting speeds and a brilliant, mirror-like surface finish on carbon and alloy steels.
CCMT Geometry (80° Positive): The CCMT shape features a 7-degree positive relief angle, which reduces cutting forces and minimizes heat transfer to the workpiece. The 0.4mm (1/64") radius provides excellent edge security, making it durable enough for semi-finishing while remaining sharp enough for final high-speed passes.
Metric vs. Imperial Comparison
| Unit System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT060204 | 6.35 mm | 2.38 mm | 0.40 mm |
| Imperial | CCMT21.51 | 0.250" (1/4") | 0.0937" (3/32") | 0.0157" |
Recommended Cutting Parameters
*The 0.4mm radius allows for standard finishing feed rates. Ensure stable clamping to prevent micro-chipping of the cermet edge.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon & Alloy Steel | 150 - 350 m/min | 0.05 - 0.20 mm/r | 0.10 - 1.20 mm |
| Mild Steel / Structural | 180 - 400 m/min | 0.05 - 0.25 mm/r | 0.10 - 1.50 mm |

Shop SCLCR 06 HoldersGrade Comparison: NX2525 vs AP25N
NX2525: The ultimate Mirror-Finish grade. It is harder and provides higher wear resistance. Best for stable, continuous finishing.
AP25N: The Versatile Cermet grade. It is slightly tougher and can handle light interruptions better than NX2525. If your setup has slight vibration, AP25N is a safer choice.

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.
