Small Hole EDM Advantages

Small hole EDM is in many ways similar to a drilling operation but offers the advantages of EDM machining.

  • Very low machining forces that make it ideal for drilling delicate parts
  • Workpiece hardness has no detrimental impact on performance
  • Angle of entry is unimportant because there is no contact between the tool and workpiece
  • Burr-free finished holes
  • Part heights up to 14”are possible, depending on part configuration
  • Maximum XY travel: X-22″ & Y-14″
  • Other sizes may be available with lead time and/or large quantity orders.

Common EDM Hole Drilling Applications

  • Coolant holes in hardened machine tool bits for taps, end mills, and drills
  • Addition of wire EDM start holes after heat treating
  • Removal of broken drill bits and taps
  • Placement of holes too small/difficult for conventional drilling
  • Burr free holes
  • Wire safety holes
