Abstract: A dresser for roughening the surface of an abrasive wheel has a cutter means for rotation in contact with the abrasive wheel. The cutter means includes a plurality of cutter teeth mounted on a cutter shaft. Ball bearings at each end of the cutter shaft permit the cutter means to rotate freely when held against an abrasive wheel as the wheel is rotated. A pair of hexagonal bearing supports each define a bearing receiving recess for receiving the ball bearings mounted at each end of the cutter shaft. Each of the bearing supports also defines a threaded, bolt receiving opening. A dresser body defines a cavity receiving the cutter unit and slots on opposite sides of the cavity receiving the bearing supports. The dresser body has bolt holes extending from the exterior of the body into the cavity through each of the slots. The dresser body includes a dresser handle which permits the dresser to be manipulated manually.
