High-Speed Steel Finishing | NX2525 Cermet | Robust 0.8mm Radius
Superior Surface Finish Technology
Machinists searching for a competitive Mitsubishi DNMG150408 NX2525 price are looking for more than just an insert—they are looking for a way to achieve mirror finish turning on steel parts. The NX2525 is designed to outperform carbide in high-speed, light-duty applications.
NX2525 Grade (Premium Cermet): Unlike standard tungsten carbide, the NX2525 cermet grade for steel is a micro-grained ceramic-metallic composite. It has a significantly lower chemical affinity for steel, which virtually eliminates Built-up Edge (BUE). This means your tool stays sharp longer and your workpiece glows with a high-luster finish.
0.8mm Radius (Structural Reliability): The "08" (1/32") nose radius provides the perfect balance between edge strength and surface quality. It is robust enough to handle semi-finishing passes while still delivering the high-precision CNC finishing required for aerospace and automotive tolerances.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150408 | 12.70 mm | 4.76 mm | 0.80 mm |
| Imperial | DNMG432 | 1/2" | 3/16" | 0.0315" (1/32") |
Recommended Cutting Parameters
*Cermet requires high speeds to prevent edge chipping. Not suitable for heavy roughing.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045/45#) | 180 - 400 m/min | 0.10 - 0.30 mm/r | 0.50 - 2.00 mm |
| Alloy Steel (4140/SCM440) | 150 - 320 m/min | 0.08 - 0.25 mm/r | 0.30 - 1.50 mm |

NX2525 (Mirror Polish Expert): Best used for finishing cuts where a grind-like finish is desired. It excels at high speeds but is brittle.
VP15TF/US735 (Interrupted Cut King): If your part has keyways, splines, or requires heavy material removal, switch to Mitsubishi carbide grades. Cermet will chip under high impact or when the cut is heavily interrupted.

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.
