Air cooled CNC spindle motor delivers stable high-speed cutting with efficient heat dissipation for cleaner engraving and milling results. Built for CNC routers and engraving machines, it runs up to 24,000 RPM with dynamic balance to reduce vibration and noise. The ER20 collet interface supports common tool shank sizes for fast bit changes and consistent accuracy, while four precision bearings help maintain smooth rotation during long jobs.

Upgrade a CNC router spindle setup with a square-body, air-cooled design made for high-speed work and reliable daily operation. The 220V, 400 Hz build is intended for use with a frequency converter/VFD, helping you dial in speed for different materials and tool sizes. From detailed engraving to heavier milling passes, this spindle is engineered to stay stable, accurate, and easy to integrate into many CNC builds.
