Little help for industrial guy from residential

I'm the first to do that too. But from what the OP is saying about the joist bay above the concrete block that has been firred out and finished, I run into that, and that little drill will let you reach in and drill up through the shoe at the outside wall into the bay. I use a short 4" auger that will fit up in 2x12 joist bays. I suppose if you had 2x10 joists you could cut the auger bit shank off by a couple of inches.

At the very least you can use that drill to drill down through a hole cut in the sheetrock, smaller than what you would need with a regular right angle drill and extension bit.

I've used those flexi-bits and find them useless. Might as well cut out the sheetrock because that's what you will be doing anyway after you use one of those... if the auger doesn't break off.
