An apparatus producing an aperture through a workpiece of brittle material such as ceramic or glass which includes a piezo electric transducer to generate longitudinal vibrations at a frequency within the range 20-40 kHz, and transmit the vibrations to a tip adapted to contact the workpiece. Additionally a motor generates small amplitude movements of the tip at a frequency in the range of 10-100 Hz in a plane transverse to the direction of the longitudinal vibrations.
