ABSTRACT:
A mounting assembly for rotatably mounting a surface processing tool holder on at least one motor driven rotatable arm of a surface processing apparatus, such that the tool can spin freely as the arm is driven by the motor, includes an elongate shank having a smooth surfaced, cylindrical portion intermediate its ends adapted for positioning within an aperture in the tool holder with one threaded end portion projecting through the aperture for attachment to an elongate mounting bar adapted for attachment to the arm. A bearing supported by the tool body and surrounding the smooth surfaced portion of the shank is rotatable relative to the shank. The mounting bar includes a threaded aperture for receiving the threaded end portion of the shank and the threaded aperture includes a counterbore for receiving the end portion of the smooth surfaced shank portion which is adjacent the threaded end portion.
