High-Speed Steel Finishing | NX2525 Cermet Grade | Precision 0.4mm Radius
Unrivaled Surface Quality in Steel Finishing
When looking for a competitive Mitsubishi DNMG150404 NX2525 price, you are investing in Cermet technology that eliminates secondary grinding processes. This tool is the master of high-speed light turning.
NX2525 Grade (Advanced Cermet): The NX2525 cermet grade for steel is a composite of ceramic and metallic materials. Because it has a low affinity for steel, it effectively prevents Built-up Edge (BUE). This allows for significantly higher cutting speeds than carbide while maintaining an incredible mirror finish turning quality on carbon and alloy steels.
Standard Geometry (Precision Finishing): The 150404 configuration with a 0.4mm radius is optimized for light finishing passes. It minimizes radial cutting forces, which prevents deflection on long or slender workpieces, ensuring your high-precision CNC finishing remains within tight tolerances.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150404 | 12.70 mm | 4.76 mm | 0.40 mm |
| Imperial | DNMG431 | 1/2" | 3/16" | 0.0157" (1/64") |
Recommended Cutting Parameters
*Cermet requires high speeds to perform correctly. Avoid low-speed machining which can cause chipping.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (S45C/1045) | 150 - 350 m/min | 0.05 - 0.20 mm/r | 0.20 - 1.50 mm |
| Alloy Steel (4140/SCM440) | 120 - 300 m/min | 0.05 - 0.15 mm/r | 0.20 - 1.20 mm |
Compatible Tool Holders
For vibration-free finishing, use high-rigidity 15-series holders:
Shop DDJNR 15 HoldersPro-Tip: Cermet (NX2525) vs. Carbide (VP15TF)
NX2525 (High Speed Finishing): Best for finishing cuts in steel where you need the best possible surface shine and dimensional accuracy. It lasts much longer than carbide at high RPMs.
VP15TF/US735 (Toughness): Switch back to carbide if you have interrupted cuts or need to rough out material. Cermet is brittle and will chip if subjected to heavy impact or low-speed "gummy" conditions.
