A boring tool is made from simple bar stock without significant external machining of the tool body. By providing a longitudinal bore which intersects a transverse slot, a longitudinally slidable wedge with splines can cooperate with a disc carried by a tool bar slidably received in the transverse slot. To ensure the most precise alignment between splines of the wedge and splines of a cooperating disc in the tool bar, the disc of the tool bar is attached to the tool bar with epoxy cement while the splines of the disc are engaged with the splines of the wedge. With the splines of the wedge being angularly offset from the longitudinal axis of the wedge, translation of the wedge will ensure accurately controlled movement of the tool bar.
