Small Hole EDM Materials Cut

Materials Cut

Most all electrically conductive materials can be drilled using small hole EDM. However, aluminum can prove to be especially difficult. During the drilling process aluminum oxide formation will stop current flow and the ability to drill. We have to take a close look at aluminum parts to see if they are feasible to drill with small hole EDM.
