Both models are available with and without (AEC) Automatic Electrode Changer Units and come standard with LCD touch screen monitors to allow input of drilling and cutting programs and parameters.  Dielectric fluid filtration units are also available as an option.  These Small Hole EDM Machines can use electrodes from .003-.156-inch diameters without the optional AEC unit and from .012-.118-inch diameters when ordered with the optional AEC unit. 

Portable Tap Buster or Broken Tap Remover EDM Machine  

Also know as the EDM-DR, this unique EDM Machine can be brought directly to wherever you need to EDM out a broken tap or drill.  This means you never need to remove and lose the positioning of your big or small parts just to be able to remove a broken tap or drill.  This Tap Buster/ Broken Tap Remover uses normal tap water as the dielectric and with its standard internal pump it can use brass or copper single hole or multi hole electrodes from .039-.256-inch diameter.  This EDM machine uses 220VAC, 5A single phase power and with the optional 110-220VAC buck boost transformer allows you to plug into any 110VAC wall outlet in your facility.
