I managed to break off a 6-32 tap in a 304 SS block last week, and searched for several hours trying to find an easy method to reclaim the part. The tap was in over 1/2 inch deep when it snapped and it was stuck solid! I know, 6-32 is a weak tap, and the hole was far too deep, but that is what the customer wanted. At least it was a through hole.
I finally resorted to chemical methods (Nitric Acid) in this case, and the part was saved without damaging anything other than my wallet.
I attached 4 files file with the details of the chemical method I used, plus some other methods that are possible. PLEASE read the "Read Me First" file and be careful if you try any of these chemical methods, since serious injury or death is possible if proper procedures are not followed. I also recommend downloading and following the MSDS procedures for safe handling and disposal of any chemical used. These can be found easily with a simple internet search (Google Nitric acid MSDS for example)
