Abstract
A tool mounting for a planing machine in which the cutting tools are exposed to high tangential forces. The tool is held on a rotary drum by a wedging action so as to be more readily replaced. The tool may comprise separate adapter and cutter bit components, or in the form of a one-piece member. The tool adapter includes a projection extending from an end opposite from the cutting tool. The projection includes a first contact surface and the mounting includes a second contact surface located outwardly from the first contact surface which first and second contact surfaces converge toward one another. In this way, the first and second contact surfaces cooperate with corresponding surfaces on the cutting head to wedgingly secure the adapter thereto. In a further embodiment of the present invention, the adapter includes a through-hole communicating with the bore for receiving the tool such that a projection on the recessed casing for the tool can enter the through-hole and the bore to rotatably mount the tool whereby disengagement of the adapter also disengages the tool from the adapter.
