In non-ferrous metal precision machining, especially when cutting highly ductile and adhesive materials such as pure copper, cutting tools must meet extremely high standards for sharpness, chip evacuation, and anti-adhesion performance. At the same time, high-speed machining of aluminum alloys and resin materials requires a careful balance between cutting efficiency and consistent surface finish.
The SAMHO DLC-coated 4-flute square end mill series (D1–12 mm) is specifically engineered for these demanding applications. Its low-friction DLC coating significantly reduces built-up edge formation during copper machining, improving cutting stability and extending tool life.
The 4-flute geometry enhances feed rates while maintaining rigidity and cutting smoothness. This design allows stable performance in both high-speed aluminum milling and precision machining of resin materials.
Advanced Technical Features
DLC High-Lubricity Coating for Extended Tool Life
This DLC-coated end mill uses advanced Diamond-Like Carbon low-friction coating technology to deliver excellent anti-adhesion and wear resistance in non-ferrous metal machining.
Superior Anti-Adhesion Performance：When machining highly ductile materials such as copper, the coating effectively suppresses built-up edge (BUE) formation. This ensures stable cutting performance and improved surface finish.
High Wear Resistance and Longer Tool Life：The DLC coating significantly reduces wear under continuous high-speed cutting conditions, extending overall tool service life.
Strong Coating Adhesion：The coating maintains excellent bonding strength to the carbide substrate. It remains stable under high load and friction, reducing the risk of peeling or flaking.
4-Flute Flat-End Geometry Optimized for Copper Machining
This 4-flute end mill is specifically designed for copper machining while maintaining strong performance in aluminum alloys and engineering plastics.
4-Flute High-Rigidity Design：The 4-flute structure improves feed rate capability while maintaining cutting stability in medium-to-high speed operations.
Flat-End Cutting Geometry：Suitable for face milling, slotting, and contour finishing. It ensures accurate geometry and consistent machining results.
Optimized Cutting Edge for Copper：A sharp and refined cutting edge reduces cutting resistance and improves chip control, especially in sticky copper materials.
