given the way everything is set up, I do need to go through the poured

the sill plate etc.

I have been looking at information online about hammer drills and possibly
rotary hammers. *I can find YouTube videos etc. that show people drilling
concrete, but I don't see any the show people drilling through poured

My plan is to rent a hammer drill or a rotary hammer to create the hole.

Can anyone give me an idea of how hard this is to do? *Will a hammer drill
or rotary hammer work for this? *I am thinking that maybe I can drill
several smaller holes through the poured concrete and then chip out the rest

Which is better to rent for this job -- a hammer drill or a rotary hammer?

Rent the rotary hammer to begin with. If you rent a 'hammer drill'
you will go back for the rotary. BTDT. You aren't going to make a
neat round hole with anything but a coring machine. Using the rotary
hammer drill a series of holes around the outline of your big hole and
knock out the webs with a hammer. Expect a big mess for cleanup.
