Abstract
Abstract A boring bar having an end face extending transversely to the longitudinal axis of the boring bar with a slot extending completely through the boring bar and diametrically across the end face. First and second slide blocks are disposed in side-byside overlapping relationship in the slot. The slide blocks have first ends which are disposed in the slot and extend radially in opposite directions outwardly of the boring bar to oppositely disposed second ends. A cutting element is attached to the second end at each of the slide blocks. At least one threaded fastener extends through an elongated slot in each slide block and threadedly engages the bottom of the slot in the boring bar for attaching each slide block to the boring bar and for adjusting the radial position of each slide block independently of the other. The slot in the boring bar is generally T-shaped to define guide grooves and the slide blocks are identical in configuration and include guide flanges disposed in the grooves of the slot. In one embodiment each of the slide blocks includes a gauging recess and a gauge block having gauge ends is attached to the boring bar for radially positioning the slide bars.
