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.

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;
- 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.
A drilling tool for use in machining a conductive work piece, said drilling tool comprising:
- an electrode assembly 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 a portion of said forward electrode tip;
- and
- at least one side electrode coupled to said dielectric sheath;
- and
- a protective cap positioned at least partially over said electrode assembly, said protective cap comprising a first opening and a second opening defined therein such that said inner radial portion of said forward electrode tip and said at least one side electrode are at least partially exposed.
