Gentleman,I used a mans battery operated 1/4 Dewalt impact driver (18 volt) and fell in love with it. My question is do any of you use a tool of this type? I have a 1/2 drive air operated impact gun along with a 3/8 air ratchet.My primary use will be small engine repair.I was nosing about on line and I am unsure what drive (1/4 or 3/8) to get! the 1/4 has 1550 inch pounds of torque.I think this one would do.Anyone have an opinion? Thanks, Ken
