Description
This one is looks like new old stock to me and it is super sharp, dirty from shelf time2&1/2" CUT and 2-1/2 tpi threads per inch.
RIGHT HAND THREADS.
US made by PRATT & WHITNEY.
Overall length is approx. 16"
It says Bronze HS-334 and H-9 on it.
It is a 6 Flute tap.
I measured it and it looks like it starts out cutting at 2.440" for the first few threads, then it drops to 2.070" and tapers up the the major diameter again like a taper tap.
The largest cutting diameter is 2.525"
