Just as it says, what do you guys use a 3/8" impact for? I've never had any quality air tools so I have a habit of never using them. Takes a long time to do things but I trust my hands and feel better than air tools. But if I am going to the dealership I know I'll need to use them to save time and get the job done. So I am looking at what air tools I will need. Thinking, 1/4" Air Ratchet, 3/8" air ratchet, 1/2" impact, but do I really need a 3/8" impact? Only thing I can think is since the IRs I am looking at are 180 and 280 ft-lbs. I could use them to tighten things and just leave it at that, still like the idea of finishing tightening by hand.
