ABSTRACT:
A generally cylindrical, vertically vibrating peening tool has an integral, small diameter, cylindrical pilot at its lower end, adjoining a larger upper body portion of said tool at an annular juncture area having an outwardly concave surface at all circumferential points therearound. Supported below said peening tool is a resiliently yieldable anvil having a cylindrical top opening receptive of said pilot with a close sliding fit. The top of the anvil is flat and supports a workpiece between the tool and the anvil with a hole in the workpiece aligned with said pilot, enabling the latter to extend through said hole and into the anvil's said top opening. The workpiece is shiftable horizontally upon the anvil to enable all portions of the upper edge of said hole to be brought into peening, deburring engagement with said concave juncture area of the peening tool.
