A rotary brush for use with a surface finishing tool with a drive shaft for transmitting rotary motion to the brush. The brush is in the form of a circular disc that supports circumferentially disposed brushing elements, and includes a nut having internal threads for engagement with the drive shaft. The nut extends axially outward from each face of the disc an approximately equal distance to facilitate bi-directional mounting of the brush on the drive shaft. |
