I have a Milwaukee M18 FUEL 2780-20 Cordless Brushless Grinder 4 1/2 5" 18 Volt. I love it. It runs a long time. Gets in hard to reach spots. I also have the
Milwaukee M18 2663-20 Cordless 1/2" High Torque Impact Wrench 18 Volt. Not Cheap but worth the investment! Again, the Batteries last a Long Time. (Same batteries ONE charger!)
Good Luck & Merry Christmas.
