A pavement planing device including a rotating wheel on which cutter holders are pivotally mounted. A restraining stop member mounted on the wheel restrains outward swinging of the cutter holders as the wheel is rotated. Retraction stop members mounted on the wheel are engaged by the cutter holder members as they swing backwardly following impact with the surface of the pavement. The cutter holder members rebound from the retraction stop members to cause multiple tool impacts on the surface.
