A device for stabilizing a workstock in a slotted broach tool guide sleeve while a key broach tool extending through the guide sleeve cuts a key slot in the annular bore wall of the workstock. In a preferred embodiment the device is characterized by a pair of top and bottom end plates, each provided with a semicircular notch for receiving the cylindrical guide sleeve at opposite ends of the workstock, after the workstock is positioned on the guide sleeve. Each end plate includes a beveled surface which engages the corresponding open end of the workstock and a plate mount bolt is extended through the end plates and the workstock bore and a nut is threaded on each end of the bolt to secure the end plates against the workstock. The guide sleeve with the assembled device is oriented in a vertical position, with the lower end of the guide sleeve typically secured between the adjacent support plates of a work bench or table and the bottom end plate resting on the work table. As a hydraulic press is operated to extend the key broach tool downwardly through the guide sleeve and workstock to cut a keyway in the annular bore wall of the workstock, the end plates assembled on the guide sleeve prevent lateral displacement of the workstock on the guide sleeve and stabilize the workstock against the cutting edge of the key broach tool. A semicircular keeper can be placed on the work table in engagement with the guide sleeve for stabilizing the key broach tool in the guide sleeve.
