Within this article a novel hybrid machine tool is presented that unifies the micro-manufacturing processes Laser Helical Drilling and Electrical Discharge Machining. Hereby a flexible and highly precise fabrication of cylindrical and conical micro drill holes is possible. Furthermore the machine tool provides an opportunity for fabrication of drill holes with freeform geometries at high aspect ratios and short machining times. Application fields of these drill holes are located e.g. in the automobile and aircraft industry, mold and die making and the plastics processing industry. Besides a detailed explanation of the machine tool, the article also includes a presentation of machining results and potentials related to combined machining
