ABSTRACT:
An electochemical drilling device in which the plurality of electrode tubes are guided into hole drilling position by guide elements, one for each tube, which are resiliently moved into engagement with the workpiece, thereby compensating for irregularities in the workpiece. These guides move generally substantially at right angles to the tubes and may have notches for engagement with opposite surfaces of the workpiece adjacent to the position of the holes to be drilled therein.
