Notes about EDM:

  • Doesn’t stress the work piece as with grinding or milling
  • Keeps it cooler, limiting expansion of workpiece (which would harm accuracy)
  • EDM drills for holes too small for a drill bit
  • EDM drills for holes on angles
  • EDM drills for holes within recess
  • EDM drills for deep, small holes
  • Wire EDM for cutting squares
  • Wire EDM for cutting through thick material
