Mitsubishi VNMG160408 NX2525
High-Performance Cermet Grade for Mirror-Finish Steel Machining
The Mitsubishi VNMG160408 NX2525 is a premium 35° rhombic negative-type cermet turning insert. Unlike traditional carbide, the NX2525 cermet grade utilizes a ceramic-metal composite to deliver a mirror-like surface finish and exceptional dimensional stability. This VNMG 332 ANSI equivalent is specifically engineered for high-speed finishing where aesthetic gloss and high surface precision are the top priorities.

NX2525 Cermet Grade Technology
NX2525 Cermet: Cermet (Ceramic + Metal) offers a significantly lower chemical affinity for steel compared to carbide, which effectively eliminates built-up edge (BUE). The NX2525 micro-grain grade provides the perfect balance between high-speed wear resistance and edge toughness, making it the premier choice for dry machining and high-velocity steel finishing.
Stable Geometry: The 35° profile is optimized for intricate profiling and narrow-clearance CNC lathe finishing. It ensures stable chip flow and minimizes work hardening on the workpiece surface.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon Steel (Finishing) | 150 - 350 m/min | 0.10 - 0.25 mm/rev | 0.3 - 1.5 mm |
| Alloy Steel (Precision) | 120 - 300 m/min | 0.08 - 0.20 mm/rev | 0.3 - 1.2 mm |
Tool Integration
Ensure maximum gloss and surface quality by pairing this VNMG 332 insert with high-rigidity tool holders.
Shop Compatible DVJNR/L Tool HoldersPro-Tip: Cermet vs. Carbide
NX2525 Cermet is superior for high-gloss finishing because it maintains a sharp edge longer and resists chemical welding. However, for heavy interrupted roughing, carbide grades like UE6110 or MC6025 are recommended due to their higher impact strength.
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.
