Review on 22-Piece Screw Extractor Set - Easily Remove Stripped Or Damaged Screws With HSS Broken Screw Remover Kit, Magnetic Bit Holder, And Socket Adapter From Nuovoware by Dave Sapp

I was hoping to use this to remove a screw with a 2.5 hex hole that was stripped. The head form the set fit perfect and locked in the hole and as soon as I turned it broke off in the screw leaving me with a disaster. It broke off easily but of course was made of very hard steal and therefore impossible to drill out or remove. Fortunately I was able to get the screw to turn by tapping the side with a chisel and rotating the screw. A technique that would only work with a screw with a large head.
