Aluminum end mills are designed specifically for high-speed machining of aluminum and non-ferrous materials. They typically feature fewer flutes (2 or 3), large chip gullets, sharp cutting edges, and polished flutes to prevent chip adhesion. These tools enable excellent chip evacuation, smooth surface finish, and high feed rates. Aluminum end mills are widely used in aerospace components, automotive parts, and general CNC production where efficiency and surface quality are critical. When selecting aluminum end mills, focus on flute design, coating type (or uncoated), and rigidity to ensure stable performance in high-RPM machining.
