This 1.5kW air cooled square spindle is ideal for small to mid-size CNC routers. The square-body design provides excellent rigidity and easy mounting, while the air-cooled system eliminates the need for pumps, tubing, and coolant, making setup simpler and low-maintenance.

The spindle uses an ER11 collet system suitable for finer tools and engraving work. Built with high-precision bearings, it delivers smooth rotation, accurate cutting performance, and long service life.
