This paper deals with production of micro polycrystalline diamond (PCD) drill by wire electrical discharge machining and drilling to quartz glass with 0.3mm diameter PCD drill. In the production test the relation between electric conditions of wire-EDM to PCD and surface roughness and edge quality of PCD drill was shown. In the drilling test, tool wear, generated chips, chipping at hole entrance and inner surface of holes were investigated. As a result, it was found that roughness of PCD by wire-EDM is governed by uneven distribution of Co and electric current and that voltages less than 60V cause the unstable machining condition.
