These instructions can apply to a micro or standard sized spiral fluted extractor with drill out ends.
Equipment you will need:
Depending on the size of the screw or bolts being removed you will need:
Drill
Micro or standard spiral fluted extractors with drill out ends
Adjustable spanner or mole grip pliers
Vice
Step 1 – Attach extractor to drill
Place the extractor into the drill with drill out end facing out. Set the drill to reverse or anti-clockwise.
Step 2 – Place and use drill out
Place the tip of the drill out on the screw or bolt as close as you can to the centre. Squeeze the trigger to start making a hole; make sure to keep lifting the drill out to make sure you are in the centre.
Step 3 – Change to opposite end of extractor
Once you have created a suitable hole, flip the extractor to expose its opposite end.
Step 4 – Use spiral extractor
Keep the drill in reverse or anti-clockwise. Place the spiral extractor into the pre-drilled hole and lightly pull the trigger of the drill.
Step 5 – Extract screw or bolt
Once it is has gripped the screw or bolt you can carry on until it is completely removed.
Step 6 – Remove screw or bolt
Sometimes the extractor can get stuck in the screw or bolt. If this happens, place the screw or bolt into a vice and tighten it so it’s held securely upright. Grip your adjustable spanner or vice grip pliers and twist the extractor clockwise to remove it from the screw or bolt.
