The Pinnacle of Surface Integrity
NX2525 Grade (Uncoated Cermet): The NX2525 is a high-performance cermet (ceramic-metal composite) grade. Unlike coated carbides, this uncoated cermet maintains a much sharper cutting edge for a longer duration. Its high resistance to Built-up Edge (BUE) and superior chemical stability at high temperatures ensure that your workpiece achieves a brilliant, glossy finish without the dulling effect of traditional carbide.
FH Chipbreaker (Fine Finish Power): The FH geometry is a "sharp-edge" design. It is optimized for light depths of cut where chip control is usually difficult. The FH breaker curls the chip tightly even at feed rates as low as 0.05mm, preventing "stringers" from scratching your finished surface.
0.4mm (1/64") Precision Radius: The small 04 radius minimizes cutting resistance and tool pressure. This is essential for preventing vibration on small-diameter parts and achieving tight tolerances on final finishing passes.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CNMG120404-FH | 12.7 mm | 4.76 mm | 0.40 mm |
| Imperial | CNMG431-FH | 1/2" | 3/16" | 0.0157" (1/64") |
Precision Finishing Parameters
*NX2525 requires stable setups. Higher speeds yield better gloss. Avoid heavy interruptions or heavy depths of cut.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Low/Medium Carbon Steel | 180 - 450 m/min | 0.04 - 0.18 mm/r | 0.10 - 0.80 mm |
| Alloy Steel (Hardened) | 120 - 300 m/min | 0.04 - 0.15 mm/r | 0.10 - 0.60 mm |
Compatible Tool Holders
For high-gloss finishing, use DCLNR/L 12 series holders with high clamping rigidity:

NX2525 (High Precision): The uncoated cermet choice for maximum surface gloss and dimensional precision. Perfect for high-speed continuous finishing.
AP25N (Coated Cermet): Choose AP25N when you need slightly more wear resistance at higher speeds or for light semi-finishing tasks where the tool life of uncoated cermet might be limited.
