27mm 1.25 Pitch Tap

I have worked on a lot of different types of machinery in my life lifetime. Everything from air conditioning to Nuclear power plants on Navy surface ships and submarines to gas turbine powered generators and cogeneration plants as a civilian, and there have been countless times a tap like that would have been a dream!
I'm almost ready to retire now and I think that i just might have to try making some of those for m y sons who are in the trades.

I always seem to need a special tap like this for blind holes. sucks to be me.
