Small Hole EDM (Hole Pop EDM)

High-precision EDM drilling for aerospace, defense, and medical applications requiring tight tolerance micro-hole production.

Small Hole EDM Hole Popper Machine

Small hole drilling EDM (hole pop EDM) uses a hollow electrode to create precise high aspect ratio holes in conductive materials using controlled electrical discharges.

Ideal for hardened metals and precision components where conventional drilling would cause stress or distortion.

Hole size is determined by electrode diameter, ensuring repeatable accuracy and tight tolerance control.

Dielectric fluid continuously flushes debris for clean, deep, and stable hole formation.

Applications

  • Wire EDM start holes
  • Cooling channel drilling
  • Vent and ejector pin holes
  • Deep blind hole machining
  • Fastener / tap removal

Key Benefits

Burr-free drilling in hardened materials without mechanical stress or tool wear.

High repeatability and precision for mission-critical aerospace and medical components.
