Rainbow Single-Flute Aluminum Specific Carbide Spiral End Mill for CNC Engraving Machine

We craft this end mill from premium carbide, designed as a single-flute spiral tool for dedicated aluminum and aluminum alloy machining. Its rainbow coating enhances wear resistance and reduces friction, while the single-flute structure ensures smooth chip evacuation—critical for aluminum’s soft properties. Tailored for CNC engraving machines, it delivers high-precision carving with a glossy surface finish. Built with strict craftsmanship, it’s reliable for industrial aluminum engraving tasks needing consistent, clean results.
