Abstract

The hand-held electro-discharge machining fastener removal device of this invention brings an EDM electrode and its supporting ground pin and dielectric fluid structure to a fastener in a workpiece, such as an aircraft fuselage. The hand-held device brings the dielectric fluid, power supply, and control system structure to the fastener in a compact tool to permit EDM machining to be brought to large structures.
