<p>An apparatus for producing holes in dielectric workpieces in the form of thin sheets and substrates, in particular of glass or glass-like materials and semiconductors is provided. The apparatus includes individual high-voltage electrodes that are symmetrically arranged on an electrode holder around the hole to be produced in the workpiece. The apparatus also includes individual counter electrodes that are arranged on a counter electrode holder. The electrodes and counter electrodes can be connected in a permutating manner to a high-voltage source for the discharge of high-voltage flashovers.</p>
