I've just stripped the gears in my close-quarter 379-1 Milwaukee drill again so it's time for something a little
heavier. Primary use is drilling 5/8" up to 1" holes through studs and joists for house wiring. The idea of 4 1/2"
capacity for the odd drain or whatever is nice. These are my possibilities so far. Prices are close enough not to care.
