ABSTRACT:
A roll peening device includes a shank having a head with an annular groove that carries at least one ball which is held therein by a retainer such that the application of the ball to a workpiece in combination with rotating motion causes deformation of the workpiece and is particularly useful in a process of retaining a part in an opening.
