(54) Disc brush


(57) A disc brush (10) has a disc (20) having a face (22) including at least a first portion (24) and a second portion (26). A plurality of abrasive filaments (40) are fixed to the first portion (24) and extend generally perpendicularly from the disc. The abrasive filaments (40) are arranged around the second portion (26). The second portion (26) is recessed from the first portion (24) to form a recess (28) having a diameter and axial depth sufficient to receive at least a portion of a raised portion of a work piece. In one preferred embodiment, the disc brush (10) is provided with an arbor hole (32) to allow the disc brush (10) to be driven by a rotary drive device and is sized to fit within a well portion of an automobile wheel (50) to allow the disc brush (10) to be rotatably driven to de-burr an interior portion of the wheel.
