I'm thinking with the Milwaukee battery tools I could up it a little just tossing in a 3/8 impact wrench to accompany the standard tools. Figure if I need the 1/2 " wrench it might be more than I want to be messing with roadside
and the Milwaukee 1/2" is big and heavy but has gobs of torque. Rarely use mine here at work, 3/8" does most. Could throw a 1/2" breaker bar in the bag if concerned.
