The Science of Cermet Finishing
NX2525 Grade (Titanium-Based Cermet): NX2525 is a high-performance Cermet grade known for its excellent oxidation resistance and high hardness at elevated temperatures. Because Cermet has a low chemical affinity for ferrous materials, it prevents "welding" of the workpiece to the tool, resulting in a superior surface finish that carbide simply cannot match.
FV Chipbreaker (High-Speed Finisher): The FV geometry is optimized for High-Speed Finishing. It features a sharp cutting edge and a specialized chip pocket that ensures tight chip control even at the very shallow depths of cut required for final passes.
0.2mm Micro-Radius: The 02 (0.0079") radius is specifically designed for Ultra-Fine Finishing. It generates minimal radial force, drastically reducing the risk of chatter on thin-walled parts or long-reach boring operations.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT060202-FV | 6.35 mm | 2.38 mm | 0.20 mm |
| Imperial | CCMT21.50.5-FV | 1/4" | 3/32" | 0.0079" |
Recommended Finishing Parameters
*NX2525 Cermet performs best at higher speeds without heavy coolant. Dry machining is often preferred for mirror finishes.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Mild Steel (Low Carbon) | 180 - 450 m/min | 0.03 - 0.12 mm/r | 0.10 - 0.80 mm |
| Alloy Steel / Stainless | 120 - 300 m/min | 0.03 - 0.10 mm/r | 0.10 - 0.60 mm |

NX2525 (Cermet): Use this when you want a polished, shiny finish on steel. Cermet can run at much higher speeds than carbide but is more brittle.
VP15TF (Carbide): Switch to VP15TF if you have interrupted cuts or unstable setups. Cermet will chip under impact, whereas carbide absorbs the shock.

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.
