Electrical Discharge Machining Tube Electrodes
With One Channel
With Two Channels
Create very small holes, including pilot holes to run EDM wire through. For use in hole-popping EDM machines.
Also known as spark machining, electrical discharge machining (EDM) uses electrical current to erode a metal workpiece to a desired shape.
Brass electrodes can be used at a faster machining rate but wear out quicker than copper electrodes.
Electrodes with one channel are best for creating through holes.
Electrodes with two channels are best for creating closed-end holes. The internal channels disintegrate material left at the bottom of a closed-end hole.
