Build Your Own Electrical Discharge Machines

Learn more about Electrical Discharge Machining (EDM) and the tools available to make beautiful custom jewelry, remove broken bolts and taps, and "burn" unique shapes into your workpiece.


Electrical Discharge Machining (EDM) is a process that uses electrical discharges from an electrode to erode an electrically conductive material. As a result, it is possible to erode or "burn" the shape of the electrode into the workpiece. If you need a square hole, (or other unique shape) in a part make a square electrode and burn it into the part. This machine is great for removing broken bolts, taps, easy outs, drills, and studs etc. from expensive work pieces!
