Abstract: A sander comprises a body member molded of polypropylene to which a soft pad member is integrally molded or directly bonded thereto. Preferably, the material comprising the pad member is of a thermoplastic elastomer material, such as Santoprene®.

Abstract: This manual, vacuum-enabled dustless sander provides complete debris collection from both the working surface and area extending peripherally beyond the sander head while overcoming other deficiencies of prior art by projecting an abrasive screen above the sander head to form a rectangular mound which abrades while allowing debris to be drawn through itself. The projection is achieved by placing the abrasive screen atop an air permeable cushion supported by a rectangular platform made to rotate at a position of use at the intake end of a hollow shaft. Ends of the screen are inserted between the walls of two rectangular containers which rotate on the shaft and loosely embrace the platform. Rotating the shaft moves the threaded inner down the shaft into the lower container to clamp the screen in place. Vacuumed air draws all abraded debris into the sander head and through the hollow shaft to a collection canister.
