The Performax Plus Drum Sander Features an exclusive SandSmart controlled, infinite variable feed rate from 0 to 10 feet per minute for superior finishes with no overloading. Patented, abrasive take-up fasteners mean quick paper changes while a TEFC motor prevents dust infiltration. A continuous-duty design allows heavier use for longer periods. A precision-flattened, reinforced steel conveyor bed with a no-give power feed conveyor belt offers consistently smooth feeds. The drum height and downward pressure are adjustable to eliminate snipe. The Mini sander also Features a self-cooling, machine-balanced, 5-inch by 10-inch extruded aluminum drum with zinc-plated steel tension rollers mounted next to it. An easy-to-use cast iron, height adjustment, hand wheel allows both radical height changes and minute adjustments to 1/16-inch for precise stock removal. A safety power switch with overload protection on the front of the base protects the operator from accidental starts. Operating at 1,700 RPM, the drum also Features a sealed ball bearing for permanent lubrication and smoother sanding.
