ABSTRACT:
A rotary surface treatment tool is attached to a rotational driver with a kit. The surface treatment tool includes a base with a middle portion around a center hole, and one or more attachment knobs are placed on the front side of the middle portion. An attachment plate or retainer nut has a flange which extends radially over the middle portion of the base. The attachment knobs mate with holes in the flange of the retainer nut. The surface treatment tool is tightened onto the shaft by turning the surface treatment tool, with the attachment knob turning the retainer nut and thereby tightening the retainer nut to the threaded shaft. Assembly and tightening without any tools is thus facilitated. The base may be made of a flexible, shape-retaining material, and recesses are provided behind the attachment knobs to permit use with a retainer nut without a mating recess. The surface treatment tool may be a brush having bristles which extend at about 90.degree. to the plane of the base. The bristles are disposed in a pattern of helical bristle curves, with each bristle curve providing a relatively continuous sweep.
