Abstract
An electrode for use in an electrochemical machining process comprising an outer metal skin of corrosion resistant material, an inner core of conductive material, and an insulating coating disposed on an external surface of the outer metal skin. The external surface is partially coated with the insulating coating so as to define a pattern of raised areas to be formed on an internal surface of a predrilled hole in a workpiece.
