2. Drilling a Hole

Bolts and screws rust after a particular time if it is not made with stainless steel. Sometimes the old screws get damaged due to rust, which it is not possible to extract them naturally. In this situation, you may need a bolt extractor.

The first operation with the bolt extractor is making a hole on the screw, and below I mentioned how you should do it.

  • Measure the screw you want to extract and then put the same size drill bit on the drill machine’s head. If you try to do it with the wrong drill bit, the screw can be more damaged.
  • Drill a hole along the middle, and it should be straight. If the hole is not straight, it will be much more challenging to extract.
  • Try to make the hole deeper. In this way, the bolt extractor will be able to rotate effectively and will quickly extract the screw in a short time. Also, it makes the possibility of slipping much less.
