摘要
A tool for guiding a push type keyway broach in the broaching of one or more keyways in a single bore of a workpiece includes a bushing fitable into the bore of the workpiece, a rectilinear guideway in the bushing for slidably receiving the base portion of a conventional push type broach, and a guide pin receivable in a selected one of a plurality of angularly spaced radial holes in the bushing and having an externally extending portion dimensioned to slidable fit into a previously broached keyway, thereby to precisely set and hold the broach at a selected, predetermined angle relative to the previously broached keyway.
