I only have mini diggers but wouldn't be without my makita drill adaptor grease gun. Way easier to do on your own. Bought a few M12 bits (die grinder, 90 degree die grinder and 90 degree 1/2" impact wrench'; and and I gotta say they are s**t hot. My Makita top of the line 18v impact driver has just dies after two years, so I'm thinking about going M18 for it's replacement. Milwaukee's top of the range model is way cheaper than the Makita and has more power! I can almost get the impact driver, two batteries and the charger for the cost of the bare Makita unit! WTF?? Pains me to say it after years of blue till I die, but these M12 tools have swung me.
Trouble is I need to find a battery adaptor to Makita cause I can't be doing taking two sorts of battery to every job.
