Brass Multi Channel EDM Tubes

  • A line of single hole brass EDM electrode tubes.

    Multi Channel

    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.

    Please note that the following parts list is not representative of our entire electrode selection. This
    list is meant to be used as much for reference as for actual purchasing, and represents a range, rather
    than a comprehensive list, of the products we offer. If the dimensions of a desired electrode are not
    found on this list, but lie between listed dimensions, we are capable of manufacturing it.

    Ordering Custom EDM Electrodes

    If an electrode in the desired size cannot be found in the parts list below, do not hesitate to contact us. Custom electrodes can be requested
    conforming to the following standards:

    • Tolerances for electrodes are from +.00mm to -.02mm (+.0000″ to -.0008″).
    • Lengths may be from 100mm to 700mm (4″ to 28″).
