Abstract
A nozzle for sandblasting or shot peening a workpiece comprises a base and a finger, The finger having diameter small enough to allow it to be inserted into an aperture in the workpiece. The finger has a lateral opening therein to allow peening fluid to exit and impinge an interior wall of the aperture. The base has a bypass orifice therein which allows excess shot to exit the nozzle so that the nozzle will not clog with shot. A method for using the nozzle is contemplated wherein the nozzle is reciprocated and rotated within the aperture so as to subject the entire interior wall to the peening process.
