Comes in a set with many different sizes big and small.
The problem is the set I have is they are designed for taps with 4 flutes and I have a lot of taps with 3 flutes.

The part was too exxy to scrap, so off it went to an engineering shop with a spark eroder.

I was being a bit hyperbolic then. It's only happened once to me too. I ground and bent the jaws of my old long nose pliers to fit and It came out easily. Should have borrowed the pliers, Then I could ave told the lender he owed me a Schooner for the new tool.

Billy, maybe the previously shown honeymoon pliers could have been used.

Tap removal tools are like easy outs ,only work if the bolt or tap is loose otherwise as Rick said Spark eroder

I started my Apprenticeship in 1971. Dilating fluid was already in use, so Although I had seen Honeymoon Pliers I only handled them to move them out of the way. That's a bit sad when you think about it.

Sorry all, I posted the answer to the mystery device when I got home from my nightshift, went to bed, got up and went to work again, effectively killing this thread for 24 hours which is pretty much what nightshift does to me too.
Just got home and about to go to bed again so here's a quick one, it will be easily recognisable to some but I want a certain specific detail in the answer.
