ABSTRACT:
A sanding tool having a power driven shoe carrying a sheet of abrading material which is adhesively secured to the underside of the shoe and then extends upwardly at its forward end and then rearwardly at the top of the shoe to a position of retention of an end portion of the sheet between a spring urged clamping element and an opposed surface. The clamping element is urged toward that surface with a very light yielding force which remains the same during insertion of the sheet material as during an abrading operation, and which is light enough to enable the sheet to be pushed manually rearwardly between the clamping element and opposed surface against the frictional resistance offered thereby.
