In non-ferrous metal precision machining—especially when cutting pure copper—tooling must meet extremely demanding requirements. It needs to maintain sharp cutting edges, ensure smooth chip evacuation, and resist material adhesion. Long tool life is also critical for maintaining efficiency and consistency.
The SAMHO DLC-coated 4-flute long-neck round nose end mill is specifically engineered for these conditions. It is optimized for high-efficiency machining of pure copper, while also delivering excellent performance in aluminum alloys and resin materials.
This tool features a high-performance DLC coating that greatly reduces friction. It minimizes common issues in copper machining, such as material sticking and built-up edge. As a result, it improves surface finish and maintains stable dimensional accuracy.
Advanced Technical Features
High-Adhesion DLC Coating for Extended Tool Life
This tool features a proprietary DLC (diamond-like carbon) coating engineered for red copper machining. The coating delivers an extremely low coefficient of friction and strong chemical inertness, ensuring stable performance in demanding cutting conditions.
- Excellent wear resistance: Maintains a sharp cutting edge during long, continuous machining cycles
- Strong anti-adhesion performance: Reduces built-up edge (BUE) and prevents material sticking in red copper applications
- High coating adhesion strength: Ensures stable coating performance even under high-speed and heavy-load cutting conditions
Long-Neck Corner-Radius Design for Deep Cavity Machining
The long-neck geometry combined with a corner-radius tip is designed for complex and deep cavity machining.
- Ideal for deep cavity work: Suitable for red copper molds, electrodes, and 3D contour machining
- Reduced stress concentration: Corner-radius design helps prevent edge chipping and improves tool durability
- Stable tool path control: Improves contour accuracy and machining consistency in complex geometries
High-Efficiency 4-Flute Design for Stable Cutting Performance
The 4-flute structure is optimized to balance cutting efficiency and tool rigidity.
- Smoother cutting process: Load is distributed evenly across multiple cutting edges
- Improved surface finish: Delivers high-quality finishes on red copper and aluminum alloys
- Higher machining efficiency: Supports increased feed rates while maintaining stable cutting performance
High-Strength Fine-Grain Carbide Substrate
