Tungsten Copper (WCu) is a brittle-yet-tough composite that demands specialized tooling to maintain dimensional accuracy. The SAMHO WCu Flat End Mill is engineered to handle the abrasive nature of tungsten while managing the stickiness of copper, providing a reliable solution for the most intricate CNC operations.
Advanced Technical Features
- Specialized for WCu Alloys – Balancing Strength & Conductivity
Machining tungsten copper requires a tool that can handle “hard spots” without sacrificing the sharp cutting action needed for the copper matrix. Our optimized carbide substrate maintains cutting edge stability, significantly reducing tool wear during prolonged electrode fabrication - Mirror-Polished Flutes for Uninterrupted Chip Flow
Every SAMHO WCu mill features mirror-polished flutes to prevent copper-rich material from adhering to the tool:- Superior Chip Evacuation: Rapid removal of dust and chips even in deep slots
- Clean Cutting Edges: Minimizes burrs and material smearing on the workpiece surface
- Thermal Management: Reduces heat accumulation during dry or near-dry machining
- High-Precision Square Geometry for Sharp Internal Corners
The flat-end profile is precision-ground to deliver:- Crisp Bottom Finishes: Perfect for flat-bottom pockets and slots
- Sharp Internal Edges: Critical for precision mold inserts and EDM electrode shaping
- ±0.01 mm Tolerance: Ensures repeatability across high-volume production batches
- Ultra-Fine Grain Carbide for Extreme Wear Resistance
Constructed from premium sub-micron carbide, the tool body offers maximum resistance to abrasive grain wear. The robust core design improves radial rigidity, allowing for stable, high-speed machining in narrow pockets and complex 3D features
Target Applications & Industries
- EDM Electrode Fabrication: Precise shaping of high-density WCu electrodes
- Precision Mold Making: Milling of narrow slots and sharp-cornered inserts
- Thermal Management: Machining of WCu heat sinks and electronic components
- Aerospace & Defense: High-tolerance parts made from dense non-ferrous composites
Professional Usage Recommendations
- Tip Protection: For micro-diameters (Φ0.1–Φ1.0 mm), use non-contact measuring devices to avoid damaging the fragile precision tip during setup
- Vibration Control: If chattering occurs, decrease spindle speed and feed rate proportionally to maintain surface quality
- Machining Environment: Optimized for dry machining or MQL (Minimum Quantity Lubrication). Consult our CGS2-000 Milling Conditions for tailored parameters
