625XJS

625X Spindle Series

The patented double turbine 625XJS (3/4” / 20mm Straight Shank) delivers constant high speeds under load – 30,000 to 50,000 rpm, < 0.76 hp (0.57 kW). Speed up your cycle times with this compact and powerful spindle. Ideal for contouring, mold making, milling, finishing, and drilling with small tools. Governor control maintains constant high speed and power under load. Direct drive means no heat, no duty cycle, and super reliability. Selectable rear or side air feed.
