So, rotating it counterclockwise unscrews the broken screw such that you can eventually remove it from the hole by hand. What makes the extractor an exciting tool is that it has reverse threading. As a result, the tapered end of the extractor penetrates the broken screw and firmly attaches to the head or shank. Once the extractor firmly fits into the pilot hole, turn it as you would fasten in a screw. Then, with adequate pressure, place the extractor into the pilot hole and tap the extractor into the hole with a hammer. It may be a convenient T-handle or locking plier. The pilot hole is set, so what next? Attach a grip to a suitable extractor. Also, to prevent overheating the drill bit, you may need to apply a few drops of cutting fluid before drilling.
