Abstract: A broaching cutter comprises a first shaft coupled to a cutter bit-carrying second shaft in such a way that the second shaft rotates when the first shaft rotates and is also radially displaceable with respect to the first shaft so that the second shaft revolves about the axis of the first shaft in a preselected pattern. A rotor on the end of the first shaft carries a connector in a slot in such a way that the connector is free to slide within the slot. The connector is attached to the second shaft and to a cam follower. As the connector slides, it displaces the second shaft radially with respect to the axis of rotation. The first shaft rotated within a stationary holder that has a cam race encircling the first shaft. The cam follower follows the cam race in the stationary holder, thereby varying the radial displacement of the connector. Thus, square, hexagonal or other shaped holes can be formed in a workpiece depending on the shape of the cam race.
