ABSTRACT:
A brush or pad (10) for a power sander for sanding surfaces includes a base (12) for mounting onto a power sander and a plurality of depending bristles (16) with the bristles having a plurality of hard particles (22), for example diamonds particles of grit 70 size, brazed or otherwise secured onto the bristle surface such that as the bristle wears down, new particle surfaces are exposed at the distal end (20) of the bristle to maintain sanding performance of the brush. The particles (22) may be spot brazed in steel with a brazing alloy to retain flexibility of the steel bristle.
