A sanding disk for use with power tools. The disk has four arms that form a cross-shaped structure about a central disk. Alternatively, four arms can be attached to a set of braces to form a cross-shaped structure with no central hub. The device is designed to fit in a standard drill chuck, much like a standard disk sander. To make the device sufficiently light weight, the face of the sander has a number of holes drilled in the face of the device. In addition, the arms are made of relatively thin stock. Support braces are attached to the back of the arms to ensure that the arms do not warp or bend during the sanding operation. Four rectangular sanding pads are attached to the face of the device. These sheets do the actual sanding. These sheets are commercially available. The device is bolted onto a standard sanding disk plate. The disk plate is then inserted in a standard drill.
