For construction of Decks and Pergolas, what size Impact gun to use?

Building a trellis then a Pergola, then deck replacement. As I am using 6x6 posts, then 2x10x16, I will be needing to bore a hole pretty long and don't think my electric drill will be up to handle the task. Have read that an impact driver might be more for the task. Looking for suggestions on what is being used out there. Thanks.
