I have a few Ridgid pipe threading tools that I brought home last week
1) Ridgid 12-R, 1/2 to 2" dies.
(Amazon.com product link shortened)
This is a Ridgid manual threader set.
2) A bunch of Ridgid heads 65-TC like this:
I am trying to understand what I need out of this. My own guess is
that I do not really need these 65-TC heads at all, as they do not
give me any bigger pipe threading capacity, and that I can do
all my threading with set 1).
Am I missing anything?
