ABSTRACT:
A generally cylindrical, rotatable housing contains, against material axial shifting but with limited permissible lateral shifting, an approximately coaxial peening stem as a peening tool. An outer end of said tool, projecting from the housing, is formed with an encircling, continuous peening groove. The housing is formed with an uninterrupted circular series of inwardly facing projections within which the peening stem extends somewhat loosely. Upon rotation of the housing, forceful holding of a workpiece's metal edge in said groove while the workpiece is moved translationally, causes the peening tool to be rapidly hammered laterally, successively by the projections of said series; this hammering effect being transmitted by said tool to said metal edge whereby said edge is peened and deburred.
