Only other soloution i have involves a workshop set up with a pillar drill.
If you can't get a drill into the Tap, it's hard steel so may well break and blunt cheap drill bits, a trick i learnt for drilling larger holes was to use a masonary bit on a very slow rpm and it nibbles it way through rather than cut's through.
Would need a pillar drill.
Ferric Chloride sounds exciting........ soooo if some of that ended up on say.... the roof/bonnet of a car, as long as it's steel it would eat through.

You'd have to scrape through the paint to bare metal first. You need about 6 times the mass of anhydrous ferric chloride as the amount of iron you want to dissolve.
