A portable belt-type sanding device adapted for use as an accessorial attachment to a portable hand-held power drill. The sander comprises a pair of laterally spaced rollers rotatably mounted within an open-bottomed elongate body member with a bearing plate interposed between the rollers and attached to the body member to provide a firm backing for the operative portion of a sanding belt looped around the two rollers. Provision is made for coupling the power drill directly to a drive axle of one of the two rollers, and the driven roller and its drive axle are offset from the plane of the bearing plate a perpendicular distance sufficient to prevent the coupled drill body from contacting a work piece against which the bearing plate is pressed as the sander is being operated. A handle adjustably attached to the top of the body member may be positioned on either side of a line through the longitudinal center of the body member to facilitate grasping the sander with either hand while holding the handle of the power drill in a manner permitting manipulation of its on/off switch with the other hand. The bearing plate providing the supportive backing for the operative portion of the sanding belt is of sufficiently small size to permit the sander to be powered by a relatively low-power drill without danger of overloading the drill motor. Provision is also included for selectively mounting the sander on a work table with the plane of its bearing plate oriented either vertically or horizontally. |
