Can plug tap sometimes mean second and sometimes bottoming?
Here is RS's plug taps selection, some of them look like they get close to the bottom, others less so.

The names seem to vary from website to website.

when I was serving my engineering apprentceship many moons ago, I was
told that taps are named as First, Second, and Plug taps
A plug tap does not have any tapering of the threads, while the first
tap has quite a bit, and the 2nd tap has about half as much.
I hope that helps
