The SAMHO DLC-coated 2-flute long neck rounded end mill (D0.3R0.05–D2R0.2 mm) is engineered for high-precision machining of non-ferrous metals. It is especially effective for finishing copper, and it also performs well in aluminum alloys and resin materials.
The tool features a low-friction DLC coating that significantly reduces tool adhesion and built-up edge during copper machining. This improves cutting stability and surface quality.
Advanced Technical Features
High-Adhesion DLC Coating for Stable, Long Tool Life
This tool uses proprietary low-friction DLC coating technology designed for non-ferrous metal machining. It delivers strong wear resistance and excellent anti-adhesion performance.
- High Wear Resistance: Maintains sharp cutting edges during continuous machining of copper and other non-ferrous materials.
- Strong Anti-Adhesion Performance: Effectively reduces built-up edge (BUE) and material sticking during copper cutting, improving tool stability and tool life.
Long Neck Design with Rounded Cutting Edge for Deep and Complex Machining
The long neck structure combined with a rounded edge geometry improves accessibility and cutting stability in demanding applications.
- Deep Cavity Machining Capability: Suitable for deep cavity machining in copper, precision molds, and complex 3D geometries.
- Rounded Edge Design: Reduces edge stress concentration, improves anti-chipping performance, and enhances surface finish quality.
- Wide Material Application: Suitable for copper, aluminum alloys, and resin materials.
2-Flute Design for Efficient Chip Evacuation and Stable Cutting
The optimized 2-flute geometry is designed for stable and efficient non-ferrous metal machining.
- Efficient Chip Removal: Quickly evacuates chips to reduce re-cutting and improve surface quality.
- Stable Cutting Performance: Reduces cutting forces and vibration for consistent machining results.
- Better Thermal Control: Limits heat buildup and helps prevent thermal deformation in copper workpieces.
