Abstract
A drilling tool for use in machining a conductive work piece that includes a forward electrode tip including an outer radial portion and an inner radial portion. The outer radial portion includes a forward face, and the inner radial portion extends from the forward face of the outer radial portion. The drilling tool further includes a dielectric sheath that extends circumferentially about the outer radial portion, at least one side electrode coupled to the dielectric sheath, and a protective sheath that extends circumferentially about the dielectric sheath. An opening is defined in the protective sheath such that the at least one side electrode is at least partially exposed.
Claims10
A drilling tool for use in machining a conductive work piece, said drilling tool comprising:
- a forward electrode tip comprising an outer radial portion and an inner radial portion, said outer radial portion comprising a forward face, and said inner radial portion extending from said forward face of said outer radial portion;
- a dielectric sheath that extends circumferentially about said outer radial portion;
- at least one side electrode coupled to said dielectric sheath, the at least one side electrode configured for machining the conductive work piece, the dielectric sheath separating the forward electrode tip from the at least one side electrode;
- and
- a protective sheath that extends circumferentially about said dielectric sheath, wherein an opening is defined in said protective sheath such that said at least one side electrode is at least partially exposed through the opening for machining the conductive work piece.
