A tool for resurfacing the area surrounding a protruding stud, without removing the stud from the member to which it is attached, includes a quick connect/disconnect coupler at one end thereof for attachment to and removal from a conventional rotary power tool. A central longitudinal aperture in the tool opens to a distal end thereof, and an abrasive surface preparation disc having a corresponding central aperture is adapted for removable attachment to the distal end of the tool. The tool is positioned over the stud such that the stud extends into the central aperture of the tool and the surface preparation disc is in contact with the surface area surrounding the stud. Controlled rotation of the tool in place over the stud results in a desired degree of uniform abrasion of the surface area surrounding the stud.
