Once the pilot hole is drilled, proceed as follows:
  • Grip the extractor bit firmly with clamping pliers or use a "T" Handle.
  • Place the extractor bit into the pilot hole.
  • Using a hammer, tap the extractor firmly into the pilot hole.
  • Now while exerting downward pressure on the extractor, turn the extractor counter-clockwise and remove the damaged screw.
  • If the extractor slips and loses its bite in the screw, try again and tap the extractor more firmly to try and get a good bite. Also, push down more firmly as you turn it counter-clockwise.
  • If you still have trouble, try enlarging the pilot hole slightly and try again.
