What happens here

With the appropriate Millner-Haufen left-hand drill bit secured in a Milwaukee impact driver, position the bit over the center of a seized or stripped fastener. Crucially, ensure the impact driver is set to operate in reverse (counter-clockwise). Apply steady, firm pressure and activate the tool. The left-hand cutting action of the bit will gradually bore into the damaged fastener while its reverse rotation simultaneously works to unscrew and extract the bolt or screw. This is effectively shown on a seized bolt in a metal disc (e.g., a brake rotor) and then on several smaller, hard-to-remove fasteners from a metal plate, demonstrating the bits' ability to grip and back out even challenging pieces.

Goal: Successfully extract specific stripped or seized bolts/screws from a workpiece.
