Abstract: A tool for cutting a predetermined molding pattern into a work piece as it is longitudinally advanced. A molding head is adapted to be mounted to the output shaft of a motor. The head is generally-circular and includes at least one arcuate cutout in its peripheral edge for receiving a generally-circular cutter unit. The arcuate cutout is greater than semicircular so that the center of the unit lies within the peripheral edge and is therby protected from radial travel. A bayonet-type fixture and an alognment screw are provided for engaging the cutter unit to the molding head whereby multiple devices protect the operator from violent disengagement of the cutter unit from the head during high speed cutting.
