Method of electrochemical drilling of the type in which an insulating tube which surrounds the tip of a hollow electrode is positioned in closely spaced relation to an anodically charged workpiece and a cathodically charged electrolyte is passed through the electrode to impinge on the workpiece, utilizing a pulsating negative voltage on the electrolyte, the voltage having a substantial negative DC component and negative pulses superimposed thereon. |
