ABSTRACT OF THE DISCLOSURE A suction plate for a vacuum sanding device is in the form of a ring or rectangular plate spaced above a back- up pad to define a chamber, the periphery of the suction plate is spaced slightly above the backup pad for the whole periphery of the plate and the outer edge of the plate is coterminous, or nearly so, with the edge of the backup pad. In one embodiment, the suction plate is formed of a relatively flexible plastic material. A series of spacers on the backup pad edge or the rim of the suction plate may be used. In a further embodiment a flexible cone or skirt is secured to the housing and extends down over the backup pad and the rim of the suction plate. Projections on the inside of the skirt serve to maintain a space between the latter and the suction plate rim.
