EDM Small hole drilling is the production process for the forming of holes in hardened and exotic materials such as Inconel and Carbide.

EDM drills bore holes with a long brass or copper tube electrode that rotates in a chuck with a constant flow of deionised water flowing through the electrode as a flushing agent and dielectric.

Drilling can be between 0.5mm and 4mm in diameter and up to a maximum depth of 300mm

Small hole EDM is also used to drill rows of cooling holes into the leading and trailing edges of turbine blades used in jet engines. The high-temperature, very hard, single crystal alloys employed in these blades makes conventional machining of these holes extremely difficult, if not impossible.

EDM is also used for start holes for WIRE EDM particularly in hardened material.
