55-Degree Rainbow Coated 2-Flute Carbide Aluminum-Use Ball Nose CNC End Mill

We’ve engineered this 2-flute ball nose end mill with premium carbide, tailored specifically for aluminum machining. Its 55-degree helix angle and vibrant rainbow coating reduce friction and enhance wear resistance, ensuring smooth chip evacuation during high-speed CNC operations. The ball nose design delivers precise curved surface finishing, while the rigid build guarantees stability—ideal for achieving bright, burr-free results in aluminum parts across electronics, automotive, and aerospace manufacturing.
