Abstract
A drilling tool for use in machining a conductive work piece is provided. The tool includes a body portion, a forward electrode coupled to the body portion, and at least one side electrode coupled to the body portion. When electric current is supplied to the forward electrode and the at least one side electrode, material adjacent to the forward electrode and the at least one side electrode is removed from the conductive work piece. Further, the forward electrode and the at least one side electrode are selectively operable to form a bore hole having a variable geometry that extends through the conductive work piece when the material is removed therefrom.
