Ok so to get everyone pissed, has anyone considered the Makita 1/2 18v I know they have several different 1/2 impacts. I have the Makita 4.5" 18v grinder, and yard blower. My brother has the 3/8 drill and 1/4" hex impacts. I don't want a different battery, I f a bunch of tools use the battery it will stay exercised and last longer. Imo.
