    Copper Multi Channel Electrodes

    This is a consequence of the unique challenges presented by blind hole EDM drilling. Blind hole EDM drilling as opposed to through hole drilling penetrates a material but does not exit through the material. A single hole EDM electrode does not spark where the hole is, and consequently leaves a nipple in the drilled hole. Multi channel electrodes are built such that no one part of the target material is left unaffected by the sparking electrode as it spins.
