What kind and size of bit for concrete?

I need to drill a hole through a poured concrete wall in my basement to get a hose bib in the back yard.

I have a hammer drill so I figure all I need is a good bit. I figure all I need is a concrete bit, but I'm unsure if I need any special kind of bit. Also would I be better off going with 1/2, 3/4 or 1 inch hole? In addition to the hose bib at the house, I'm thinking about about running a line to my shed, which would be about a 200ft run.

If you are installing a frost proof sillcock, the inside/outside threaded end on it will require a 1 1/4" bit. If you have the hammer drill (electric, not battery) buy a 1 1/4 SDS bit. Get your pocketbook ready, as it will cost you about $50, but it will do the job.

crabjoe -

Thanks for asking that question. I just bought a hammer drill last weekend to have on hand for some work I'm doing on my basement and have the exact same question.

So just to be clear, regular old masonry bits you can get at the big boxes can be used? I'm not talking for extended, contractor type use, just the occaisional around-the-house-need-to-mount-something type use
