The tool further includes a radial bearing having an inner race, an outer race, and rolling elements, wherein the outer race is secured to the first cylindrical wall of the first cylindrical cavity. Still further, the tool includes a central shaft having proximal and distal sections, wherein the proximal section is secured to the inner race, and wherein the distal section extends from the first cylindrical cavity and includes external screw threads. The tool additional includes a chuck threadably coupled to the external screw threads, wherein the chuck includes self-centering jaws for selectively gripping a tungsten electrode along an axis of rotation established by the radial bearing.
