Cermet Milling Technology
NX2525 Grade (Titanium-Based Cermet): NX2525 is a state-of-the-art Cermet grade. In milling, heat is the enemy. Cermet's high thermal stability and low chemical affinity for steel prevent Built-Up Edge (BUE). This allows for significantly higher cutting speeds compared to carbide and produces a "jewel-like" finish on the side walls and floor of your mill-path.
H2 Chipbreaker (Milling Stability): The H2 geometry is a "Strong-Finishing" breaker. While finishing requires sharpness, milling involves constant impact. The H2 design reinforces the cutting edge to prevent micro-chipping while maintaining a positive rake angle for smooth, low-noise cutting.
Metric vs. Imperial Comparison
| System | Model Designation | Width (mm/inch) | Thickness | Radius |
|---|---|---|---|---|
| Metric | APMT1604PDER-H2 | 9.3 mm | 4.76 mm | R0.8 |
| Imperial | APMT332-H2 | 0.366" | 3/16" | 1/32" |
Recommended Milling Parameters
*Dry milling is strongly recommended for Cermet to avoid thermal cracking. Increase speed for better surface finish.
| Material Group | Speed (Vc) | Feed (fz) | Max Ap |
|---|---|---|---|
| Carbon Steels | 200 - 400 m/min | 0.10 - 0.20 mm/t | 1.5 mm |
| Alloy Steels | 150 - 300 m/min | 0.08 - 0.15 mm/t | 1.0 mm |

NX2525 (Cermet): Use for high-speed finishing passes. It produces the best surface finish but requires stable setups.
VP15TF (PVD Carbide): Use for roughing and general milling. Carbide is much tougher and can handle heavy depths of cut and shock better than Cermet.

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.
