going to drill 6x6 beams with 1/2 holes probably 12-16 of them. using an
auger type bit. low speed, steady light pressure,..just needed to know if
a variable speed 1/2 drill motor would do the job..

I've used a 1/2" drill to put that many holes in concrete with no problem.
This should be no sweat at all. Good that you are using an auger bit as
most all of the spade bits are really crappy and will take longer..
