High-Speed Mirror Finisher | NX2525 Cermet Grade | FV Precision Geometry
The Cermet Advantage & FV Geometry
NX2525 Grade (Titanium Cermet): NX2525 is a premium Cermet (Ceramic-Metal) grade. It offers superior wear resistance and chemical stability compared to standard carbide. Because ferrous metals do not "stick" to Cermet, this insert is the ultimate choice for achieving a glossy, mirror-like surface on Carbon and Alloy steels.
FV Chipbreaker (Fine Finishing): The FV geometry is a sharp-edge, positive rake chipbreaker specifically designed for Light-Duty High-Speed Finishing. It provides exceptional chip control at shallow depths of cut, preventing "long chips" from scratching your workpiece surface.
0.4mm Radius: The 04 (1/64") radius is the global standard for finishing. It offers higher dimensional stability than a 0.2mm radius while still maintaining low cutting resistance to prevent vibration.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT09T304-FV | 9.525 mm | 3.97 mm | 0.40 mm |
| Imperial | CCMT32.51-FV | 3/8" | 5/32" | 0.0157" (1/64") |
Recommended Cutting Parameters
*Cermet thrives at high surface speeds. For the best mirror finish, run without coolant (dry) if the machine setup allows to prevent thermal shock.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 200 - 500 m/min | 0.05 - 0.20 mm/r | 0.10 - 1.20 mm |
| Stainless Steel (400 Series) | 150 - 300 m/min | 0.05 - 0.15 mm/r | 0.10 - 1.00 mm |

Shop SCLCR 09 HoldersPro-Tip: NX2525 Cermet vs. VP15TF Carbide
NX2525 (Cermet): The Speed Master. Use this for high-speed finishing where surface brightness is critical. It outlasts carbide in pure finishing applications.
VP15TF (Carbide): The Toughness Master. Use carbide for roughing or interrupted cuts. Cermet is brittle and will shatter if used for heavy roughing or on parts with keyways/holes.

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.
