I'm looking at buying a drill to use at work as an auto mechanic. I wouldn't use it very often, most likely to drill out broken bolts or minor fabrication. Should I go for milwaukee m12 fuel 1/2 drill? I already have a M12 3/8 impact that I could use the batteries for. On the other hand, since I wouldn't use it very often, and only in a shop setting, Should I spring for an air drill? I was thinking of the IR 7803RA model. I figure this would last pretty much forever, the batteries wouldn't wear out, and be more durable being shuffled around in my toolbox. However, I've never used an air drill, only cordless, and am not sure if i'd be happy with it. any opinions?
