NX2525 Cermet Grade
The NX2525 grade is a specialized titanium-based cermet (ceramic-metal composite). It provides superior resistance to built-up edge (BUE) and crater wear. Unlike carbide, cermet has a low affinity for steel, making this indexable turning insert the premier choice for achieving high dimensional accuracy and exceptional brightness in the final pass.
Chipbreaker Technology
Standard TNMG geometry provides a balanced cutting edge for general-purpose stable turning. The double-sided design offers 6 usable cutting edges, maximizing cost-efficiency for high-volume CNC finishing applications. It excels in chip control across a wide range of feed rates.
Recommended Cutting Parameters
| Material Group | Cutting Speed ($v_c$) | Feed Rate ($f$) | Depth of Cut ($a_p$) |
|---|---|---|---|
| Carbon Steel / Alloy Steel | 150 - 350 m/min | 0.05 - 0.25 mm/rev | 0.2 - 2.0 mm |
| Stainless Steel (Finishing) | 100 - 250 m/min | 0.05 - 0.20 mm/rev | 0.2 - 1.5 mm |

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.
