A rotary tool for the treatment of a surface, said tool comprising:
- an annular disk of an elastomeric material selected from the group which consists of rubber and synthetic resins having an outer crown and an inner crown, said outer crown having an annular array of outwardly projecting elastically bendable teeth adapted to abrade material from said surface said teeth being of outwardly tapering frustoconical shape and having outer ends lying along a circular arc, said inner crown having a plurality of inwardly projecting formations;
- and
- a rotatable disk holder engaging said formations for rotatable entraining said disk, said formations being angularly equispaced about an axis of rotation of the tool and including axially extending passages receiving axial ribs of said holder, said holder comprising a pair of star-shaped members with axial projections forming said ribs and extending from axially opposite sides into said passages, said star-shaped members forming a socket for a drive shaft.
