Abstract
An electrical discharge machining electrode for small hole machining. The electrode is of a rod shape and includes a spiral shaped groove extending along the electrode body with a length greater than the thickness of the workpiece. The groove terminates proximate the electrode machining face for receiving a stream of liquid coolant and promoting its flow through the gap during machining. The electrode machining face is blunt and relatively planar in shape.
