Mitsubishi VCMT160408 NX2525
High-Speed Cermet Solution for Mirror-Like Surface Finish
The Mitsubishi VCMT160408 NX2525 is a premium 35° rhombic positive displacement cermet turning insert designed for high-precision steel finishing. Unlike standard carbide, the NX2525 grade offers superior oxidation resistance and lower affinity for steel workpieces, making it the industry standard for achieving high surface finish and dimensional accuracy in CNC lathe operations.

Advanced Material & Chip Control
NX2525 Cermet Grade: A composite of ceramic and metal materials. The NX2525 is an uncoated grade that provides exceptional chemical stability. It is the first choice for high-speed finishing of carbon and alloy steels, as it prevents built-up edge (BUE) and maintains a sharp cutting edge for longer periods.
MV Chipbreaker: Designed for a wide range of applications. It facilitates smooth chip evacuation and reduces cutting resistance, ensuring your precision turning tool performs consistently under varying depths of cut.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Mild/Carbon Steel | 150 - 300 m/min | 0.10 - 0.30 mm/rev |
| Alloy Steel | 100 - 250 m/min | 0.10 - 0.25 mm/rev |

Use NX2525 for high-gloss finishing and stable cutting. If you encounter interrupted cutting or require more toughness for stainless steel, consider switching to VP15TF (PVD coated carbide) or US735 for better impact resistance.
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.
