Mirror Finish Specialist | AP25N Cermet Technology | MV Finishing Geometry
Engineered for Aesthetic and Dimensional Perfection
AP25N Grade (Advanced Cermet): The AP25N is a titanium-based Cermet grade. Cermets offer higher chemical stability than standard tungsten carbide. This grade is specifically designed to prevent metal from welding to the tip (BUE), ensuring that your finished parts have a bright, polished appearance and consistent diameter over long production runs.
MV Chipbreaker (Medium-V Finishing): The MV geometry is Mitsubishi's versatile finishing chipbreaker. It features a sharp rake angle that slices through material with minimal heat generation. In finishing applications, it provides excellent chip control at light depths, preventing "stringer" chips from damaging the part surface.
0.4mm Radius (The Finishing Standard): The "04" (1/64") radius is the industry standard for high-quality surface finishes ($Ra$). It provides enough strength for a stable cut while keeping radial pressure low enough to prevent chatter on precision components.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T304-MV | 9.525 mm | 3.97 mm | 0.40 mm |
| Imperial | DCMT32.51-MV | 3/8" | 5/32" | 0.0157" (1/64") |
Recommended Machining Parameters
*Cermet performs best at high speeds. Avoid heavy interrupted cuts to maintain edge integrity.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 200 - 350 m/min | 0.05 - 0.15 mm/r | 0.15 - 1.00 mm |
| Stainless Steel (Finished) | 120 - 220 m/min | 0.05 - 0.12 mm/r | 0.15 - 0.80 mm |

AP25N (Cermet): The ultimate choice for surface finish. Use this for the final pass in mass production where aesthetic look and precision are the key requirements.
NX2525 (Cermet): While NX2525 is a legendary finishing grade, AP25N offers slightly better wear resistance in high-speed applications. If you need the longest possible life for a finishing edge, AP25N is the modern upgrade.

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.
