A sanding tool for sanding drywall corner joints is provided. The tool has
an elongated mounting plate with a swivel handle attached to one side,
and to the other side is attached one or more circular sanding disk
holders to which disks of sanding medium are removably attached to a flat
face of the sanding disk holder. The sanding disk holders are rotatably
mounted on short axles attached to the mounting plate, and are each
configured having a relatively wide edge that frictionally engages a wall
adjacent the wall being sanded. This causes the sanding disk holder to
rotate, sanding the drywall joint with a rotary motion instead of a
linear motion.
