Micro Hole Drilling

Micro Hole Drilling

Small hole EDM drilling is ideal for creating injection nozzles in molds and coolant holes in tooling, as well as start holes for wire EDM operations. Since both processes are types of electrical discharge machining (EDM), it is often more economical to use this combination for hardened materials.

micro hole drilling

Product detail

Most EDM drilling machines are CNC-controlled, however, few are actually mounted on the table of a CNC mill. By retrofitting an EDM driller onto a CNC mill, KLH offers micro hole and small hole EDM drilling services on parts over 2,200 lbs and in excess of 40" long. Size and weight are rarely a restriction when popping or drilling fast, small holes at Goldcattle.


Small hole EDM drilling is ideal for creating injection nozzles in molds and coolant holes in tooling, as well as start holes for wire EDM operations. Since both processes are types of electrical discharge machining (EDM), it is often more economical to use this combination for hardened materials.

Sinker EDM is hypothetically also capable of producing small holes, but would be more expensive and is typically 10 times slower than micro hole EDM.


Small hole EDM drilling uses the EDM principal of spark erosion to burn fast, micro holes into electrically conductive material. Unlike sinker EDM, which uses custom electrodes, small hole EDM drilling uses a brass or copper tube as an electrode. As the charged electrode is lowered into the work piece, a spindle rotates the tube to evenly distribute electrode wear, remove debris, and assure uniform roundness.
