Power polishers and power buffers rotate woven and nonwoven pads, flap wheels, and other abrasives for light material removal and final finishing. Polishers, buffers, and burnishers remove swirls, scratches, haze, and other surface imperfections from metal, wood, and plastic. Wet polishers feed water through a spindle to the abrasive to finish granite, marble, and other hard stone surfaces.
