DCMT11T304-MV NX2525
High-Gloss Cermet | MV Versatile Chipbreaker | Steel Finishing Master
Superior Aesthetics via Cermet Technology
NX2525 Cermet Grade: The NX2525 is a premium Cermet (Titanium Carbonitride) grade. Unlike tungsten carbide, Cermet does not react with steel at high temperatures. This prevents the "welding" of micro-particles to the edge, resulting in a mirror-like surface finish and excellent dimensional consistency over long production cycles.
MV Chipbreaker (Versatile Finishing): The MV (Medium-V) geometry is designed for stability. It covers a wider range of cutting depths ($Ap$) and feed rates than ultra-fine finishers. It ensures smooth chip evacuation, preventing scratches on the workpiece during high-speed finishing passes.
0.4mm Precision Radius: The "04" (1/64") radius is the perfect balance for finishing. It offers enough edge strength to resist micro-chipping while maintaining the sharpness required to reduce radial pressure and eliminate vibration.

Recommended Cutting Parameters
*Cermet thrives at high surface speeds. Ensure machine rigidity for optimal results.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045) | 180 - 400 m/min | 0.08 - 0.25 mm/r | 0.20 - 1.50 mm |
| Alloy Steel (4140) | 150 - 350 m/min | 0.06 - 0.20 mm/r | 0.20 - 1.20 mm |

NX2525 (Cermet): Best for the final finishing pass on steel to achieve a high-gloss look. It is harder but more brittle than carbide.
VP15TF (Carbide): Switch to VP15TF for roughing, interrupted cuts, or when machining Stainless Steel. Cermet is specifically optimized for continuous cuts in carbon and alloy steels.

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.
