ABSTRACT:
A rotary brush with removable brush elements is provided. The brush elements are disposed on a hub in a radial display. The brush elements include a resiliently flexible element which permits the brush to deflect at a greater angle from a rest position than the angle of deflection of the bristles of the brush from a normal position when the hub is rotated with the bristles in contact with the workpiece.
