High Torque, Low Speed Rotary Drive. Powered by a 10,000 RPM Air-Efficient Motor with 18 to 1 gear reduction. Low-speed torque uses "shaving action" to replace the tearing and gouging of high speed sanding. Surface heat and panel warpage eliminated along with mid-sanding cycles necessary to remove damage inflicted in high speed abuse. High torque, Low Speed makes ELIMINATOR a superb polisher with the use of the Polishing Kit option for immediate conversion.
