ABSTRACT:
A disc sander implement is provided which consists of a flexible disc shaped connector between a rigid pad and a spindle that may be connected to a driving unit, so that an abrasive sheet material on a cushion member attached to the rigid pad will remain in a flat contact on a work surface and thereby smooth it without swirl with only a slight pressure and little effort when a user of the driving unit moves the sander in a pendulum motion across the work surface.
