In non-ferrous metal machining—especially precision milling of pure copper—cutting tools must meet extremely demanding requirements. They need ultra-sharp cutting edges to prevent material adhesion, along with reliable chip evacuation and long-lasting wear resistance.
The SAMHO DLC coated 2 flute long neck square end mill (D0.1–0.8 mm) is specifically engineered for this challenge. It is optimized for high-efficiency machining of pure copper and also performs exceptionally well in aluminum alloys and resin materials.
This tool is coated with high-performance DLC, which significantly reduces friction and minimizes built-up edge formation. As a result, it improves surface finish quality and extends tool life, even under demanding machining conditions.
Advanced Technical Features
High-Adhesion DLC Coating for Extended Tool Life
This tool uses proprietary DLC (Diamond-Like Carbon) coating technology. It delivers an ultra-low coefficient of friction and excellent chemical stability, making it highly effective for precision machining of non-ferrous metals.
- High wear resistance: Maintains a sharp cutting edge during long, continuous machining of red copper
- Strong anti-adhesion performance: Effectively suppresses built-up edge (BUE) formation in copper machining, reducing abnormal wear
- Excellent coating adhesion: The DLC layer remains stable on the carbide substrate, even under high-speed cutting and complex toolpaths
Long-Neck Flat-End Design for Precision Non-Ferrous Machining
The optimized long-neck geometry provides improved reach while maintaining rigidity. It is ideal for deep-cavity and micro-feature machining.
- Optimized for copper machining: Produces clean, smooth cutting surfaces with minimal drag marks
- Multi-material capability: Performs reliably in aluminum alloys and resin materials
- Ideal for complex geometries: Suitable for deep slots, narrow grooves, and fine contour machining
High-Efficiency 2-Flute Design for Stable Cutting
The 2-flute structure is designed to balance chip evacuation and cutting load, improving machining stability.
- Efficient chip removal: Reduces chip re-cutting and clogging during copper machining
- Lower cutting load: Helps control heat generation and improves process stability
- Improved surface finish: Minimizes burrs and surface defects caused by material adhesion
High-Strength Fine-Grain Carbide with Precision Grinding
Manufactured from high-toughness fine-grain carbide and finished with precision edge grinding, this tool ensures consistent performance in micro-scale machining.
- High dimensional consistency: Suitable for micro-diameter and precision part production
- Improved edge strength: Resists chipping under intermittent cutting and stress loads in copper machining
- High repeatability: Ideal for batch production requiring stable process control
