The Foredom M.SR Flex Shaft Motor (134.189-M) is the 1/6 HP, 115V hang-up motor behind one of the most widely used flexible shaft systems in professional jewelry studios and metalsmithing shops. This listing is the motor on its own: a replacement for a worn SR motor, or the base of a setup built around a speed control and handpiece you already own. Paired with a compatible speed control it runs 0 to 18,000 RPM, forward or reverse, on ball bearings.
Note: A speed control and a handpiece are required and are not included. Do not plug the motor directly into a wall outlet.
