High-Velocity Milling Specialist | Mirror Surface Cermet | H2 Reinforced Edge
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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
