The tool comprises a shank having a head at one end adjacent a square shaft portion, and a threaded portion at the other end, a deformable sleeve having a square axial hole to fit over the square shaft portion of the shank the sleeve being substantially cylindrical in shape and having at least one flat side, a flexible band, externally coated with abrasive material to fit over the sleeve, a handle member with an axial hole to receive the shank, and internal threaded member at an end of the handle member to attach to the threaded portion of the shank, to hold and compress the sleeve between the head of the shank and the handle member so the sleeve grips the flexible band.
