BELT-TYPE SANDER ATTACHMENT FOR PORTABLE POWER DRILLS Abstract of the Disclosure 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 oper- ative 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.
