Small Hole EDM Advantages


When your job requires very small holes, small-hole EDM is the solution. Conventional drilling techniques simply can't match the accuracy and tolerances required for these types of jobs, especially for hardened materials.

Small hole EDM is particularly good for:

  • Deep hole drilling
  • Angle hole drilling
  • Removing broken drill bits and taps
  • Adding wire EDM start holes after heat treating
  • Close proximity placement of small holes too small or difficult for conventional drilling
  • Placing coolant holes in hardened machine tool bits (taps, end mills, drills etc.)
