3-Flute Aluminum-Specific Extended Rainbow-Coated Carbide Straight Shank CNC End Mill

We produce this 3-flute end mill with high-grade carbide, tailor-made for aluminum machining. Its extended length enables deep-cavity or long-reach aluminum processing, while the rainbow coating enhances wear resistance and reduces friction during high-speed cutting. The optimized flute geometry ensures efficient chip removal, preventing aluminum adhesion. With a sturdy straight shank for stable CNC clamping, it’s engineered to deliver precise, smooth results—ideal for aluminum parts in electronics, automotive, and aerospace industries.
