No, urs not a revrese drill. Its a stuf=d extracor - essentiall a hard
steel self tapper with a reverse thread. You drill the end of the bolt,
and then screw this in backwards. The harder tyou try to unstock teh
bolt, the toghetr the self tap stud extractor winds itself in.

Used extensively to remove sheared studs from cylinder blocks. Standrad
piece of kit, tho probly not at B & Q.
