A perfect reason for a magdrill, the milwaukee is variable in 2 speed ranges 0-250 and 0-500, its major drawback is its 75lb weight. Sometimes it takes two people 5 minutes to get it lined up for a 30 second hole. I have a smaller, lighter, evolution mag drill but it doesn't have enough stroke to run the bigger standard bits without blocking it up, so I leave it set up with the 3/4" weldon arbor for annular cutters, no matter what you do, there is always someplace you cant use what you have.This is true, We did have a 3/4” chuck corded Milwaukee that only turned 550 rpm vs the 850 rpm for the 1/2” setup. The bigger drill was also threaded on top to take a pipe bender handle. You needed that with a bigger bit on thicker steel because you couldn’t stall that sucker.
