Abstract
A tool mechanism for machining a hole side surface, and for chamfering the ends of the hole, includes a boring cutter and two chamfer cutters oriented so that during an axial infeed of the cutter assembly the hole side surface is machined and a chamfer is formed at one end of the hole. The cutter assembly can be shifted transversely to position a chamfer cutter for machining a second chamfer on the other end of the hole. The cutter assembly is carried on a cutter support member that is swingably mounted on a tool body secured to the spindle of the cutting machine. An actuator device is movable along the tool body axis to adjust the position of the cutter support member.
