An apparatus for holding a pad to a rotary pad machine. The apparatus includes a base piece and a retainer piece. The base piece includes a plurality of base teeth and is attached to a pad driver disc of the rotary pad machine. The retainer piece includes quick-release tabs having locking ribs. When the retainer piece is inserted into the base piece, the locking ribs lock into the base teeth to hold the retainer piece to the base piece. Flanges on the base piece and the retainer piece hold the pad therebetween. To tighten the rotary pad holder, the retainer piece is pressed closer to the base piece until the locking ribs lock into the appropriate base teeth. To loosen the rotary pad holder or change pads, the quick-release tabs are pressed in towards each other which unlocks the locking ribs from the base teeth and the retainer piece can be removed from the base piece. The rotary pad holder does not over tighten or over loosen because any torque applied to the pad holder is resisted by the retainer wall edges hitting against the connecting walls of the base piece.
