625 Spindle Series
The versatile and reliable 625JS (3/4” / 20mm Straight Shank) delivers governed constant high speeds under load – 30,000 to 65,000 rpm, < 0.50 hp (0.37kW). Speed up your cycle times and reduce tool breakage with the compact 625 Series. Ideal for mold making, milling, and finishing with small tools up to 1/4” / 6mm capacity. Only 2 moving parts and air circulation over] the bearings, resulting in no heat. Get the reliability of direct-drive milling with no duty cycle and no thermal expansion. Selectable rear or side air feed.
