If you had a handheld core drill and the right bit you wouldn't even be asking, it's so quick!

The Bosch stuff will work fine and in this case the sizes work out fine...

this one is listed wrong on the HD site but it's the part number for the 17" extension

If the wall is over 18"- 20" thick it gets a little harder and it's best to sub it out.

That's what I use for service pipe. I bought a 2 piece set off eBay, 2-9/16" for 2" pipe and a smaller one for 1-1/4" pipe. I found a great price and their still going strong.

I usually go thru block but I've gone thru brick plenty of times with no problem.

But going by this thread, I should have subbed out those 30+ holes
