We currently offer the Kress and 750W HF spindle options for the Mill-it-Mini. However we are in the process of developing a low RPM spindle low lower spindle speed milling applications.
The Kress 1050-1 spindle is a very well priced entry level routing spindle. Speeds from 5,000-25000RPM.
The HF spindle is a three phase 750 Watt motor. The motor has an ER20 collet and runs via a VFD so there is no need for three phase supply. The machine runs off a single phase mains plug. The Mill-it-Mini is more than man enough for this spindle.
