ABSTRACT:
A honing tool having an elongated tubular body adapted to be supported for rotational movement about a longitudinal axis in a bore of a workpiece, and adapted for reciprocation in said bore. A transverse slot is formed in said body for the reception of a pair of diametrically disposed honing stones, and wherein the outer face is convexly formed. A spring biased retainer means is mounted in said body for individually retaining each of said honing stones longitudinally in said body. An expansion wedge-like cam means is operatively mounted in said body for pushing the honing stones outwardly into an operative honing engagement with the surface of a bore in a workpiece. Each of the honing stones includes an elongated, inverted T-shaped holder having a raised central front portion and which is formed with a rear flat face in which is formed at least one rectangularly shaped recess that communicates with an inclined expansion angle or inclined surface. The expansion angle is adapted to be engaged by the expansion wedge-like cam means. The abrasive material is U-shaped in cross section and is bonded to the raised central front portion of the holder.
