In fabricating plasma display panels, a pair of glass plates or substrates have conductive lines formed thereon which are then overcoated with a glass dielectric. In high resolution gas discharge displays, repair of open or shorted lines is frequently necessary, requiring access to the lines from the dielectric. One method of accomplishing such repairs at the plate level is to bore a hole to the dielectric over the area to be repaired, using an abrasive unit to effect the boring.
