Installation Notes

Use with a reversible drill or brace; always set the drill to reverse before engaging the extractor. Drill a pilot hole with the appropriate HSS drill bit before inserting the extractor. Wear safety glasses during use, as HSS bits and extractors can fracture under high stress. If the extractor breaks inside the fastener, removal becomes significantly more difficult, so avoid applying excessive force.
