OK .... I have a bit of an unusual approach to making holes. It differs in the details, rather than the basic way others use.
I'm a real convert to using an impact driver for drilling. To bore in wood, these bits are absolutely dyn-o-mite! when used with an impact driver:

They'll get you to a 1-3/8 diameter hole. I've never had one twist or break. If they hit a nail,they just stop drilling. It usually takes several nail hits to make a noticeable difference in the drilling efficiency. BTW, I can use extensions without problem.
What about larger holes? You know, those you might consider 'hole hog' territory? Well, I just received Milwaukee's impact with the
7/16" Hex chuck. It's designed for these bits:

I expect to be able to test this out in the next few days.
