An adapter for converting a right angle grinder into a random orbital sander which employs a sanding pad assembly, the right angle grinder having a threaded output shaft, the adapter including a cylindrical body having a bearing aperture on its front side and a threaded bore for screwing onto the threaded output shaft on its back side, the axis of the threaded bore corresponding to the axis of the cylindrical body; a bearing assembly fitted into the bearing aperture so that as to establish a second axis of rotation that is parallel to but offset from the axis of the cylindrical body; an attachment for attaching the sanding pad assembly to the bearing assembly so that the sanding pad assembly can rotate freely about the second axis; a counterweight mounted on the front side of the cylindrical body so as to be located relative to measurement along the cylindrical axis at a position that is between the center of mass of the bearing assembly and the sanding pad assembly when the sanding pad assembly is connected to the attachment means, the counterweight providing both static and dynamic balance for the adapter; and a locking mechanism located on the side of the bearing assembly that is opposite to the side on which the sanding pad assembly is mounted, the locking mechanism for preventing the attachment from rotating while the sanding pad assembly is attached to and/or disassembled from the attachment.
