Here's my 2 cents worth. I'd use a small bit for a pilot hole and then use
a step-drill (e.g. Unibit) to get it to the desired size. Those
step-drills will enlarge it to a nearly perfect round hole in short order.
What are you building that you need 140 holes for? Sounds kind of
ambitious - hi.
Cheers,
