    Abstract: An impact generating hand tool for setting gem stones in a ring mounting or the like and which is configured to facilitate accurate guidance of the workpiece engaging portion of the tool to guard against striking and possibly fracturing the gem stone. The tool includes a downwardly directed handle, and a hammer having a workpiece engaging portion at the lower end thereof which is spaced from the handle a distance sufficient to permit the operator to contact and guide the workpiece engaging portion with his little finger. The hammer is reciprocated to provide the desired impacts on the workpiece by a mechanism which includes a reciprocating shaft positioned to strike or impact the hammer at the lowermost portion of its movement, a variable speed electric motor for reciprocating the shaft, and a motor speed control switch carried on the handle whereby the frequency and intensity of the impacts on the hammer and thus the workpiece may be controlled.
