“ Covington ” Automatic Vibrating Lap

This action replaces the circular rotation used by conventional lapping machines. Covington 's new design and grooved plates gives you faster cutting. Bumper ring prevents edge damage. Pad insert enables work-piece to be polished in the same pan. One tri-knob screw releases pan for easy cleaning. Comes complete with 110v, 50/60hz motor, polish pad, bumper ring, instructions and guarantee.
