A rotary brushing tool adapted for mounting on a drive shaft in brushing machinery and suitable for sweeping or scrubbing large areas; such brushing tool comprising a plurality of similar interlocking annular brush elements joined end to end, one to the other, in coaxial alignment. The brush elements are each formed of unitary first and second members and brush bristle material held in such members by anchoring means. The unitary first member has an axial hub portion and a radial flange, as does the unitary second member, and they are mounted with their flanges adjacent one another to form a channel holding the brush bristle material therebetween. The end of the hub portion of the first member is shaped to interlock with the end of the hub portion of the second member of another brush element so that brush elements so formed are joined in this manner end to end in interlocking coaxial alignment. The brushing tool so formed is suited for construction from a variety of materials including sheet metal, but is particularly suited for plastic construction. The tool is also suited for a variety of bristle configurations including a configuration characterized by the brush bristles intersecting the brush axis at oblique angles to afford a side-to-side motion during brush rotation.
