A flap wheel includes an aluminum hub with outwardly opening peripheral slots. Flap clips also made of aluminum each holding a bundle of flaps fit snugly in the slots. The slots and clips include an elongated socket and knob construction. The socket of the slot and knob of the clip both have an arched or rounded bottom and straight parallel side walls terminating in opposed retaining keys projecting inwardly from the side walls of the slot or corresponding key ways in the clip. The outer ends of the clips include a thin wall U-shape flap bundle retention slot having a flat but skew or slanting bottom wall. The slots extend uniformly in a non-radial direction angled away from the direction of rotation. The flat but skewed bottom of the clips also slants inwardly toward the direction of rotation to position the outer edges of the flaps in the same skewed slanting direction exposing or splaying an outer edge portion of each of the faces or flat surfaces of the flaps to the work as the wheel rotates. The flap bundles may be held in the clips by fasteners or staples extending through the thin walls and the inner ends of the flaps. The entire wheel may be easily refilled, is light weight and may be recycled. The flap arrangement provides additional cut, less flap-to-flap wear, and less noise. The diameter, arbor hole size, and axial length may vary. The hubs may be ganged or stacked to vary the axial length or face width of the wheel. The content of each flap bundle may vary widely, such as any combination of sisal, cloth, abrasive paper, abrasive material or non-woven abrasive and the like.
