I need to drill one (4") hole through my poured concrete foundation wall (8"), and two holes through my (4") slab. I plan to use an electric hammer drill w/ 1/2 inch bit, drilling holes then chiseling out. Does this sound like a good approach? Would perhaps a drill powered by an air compressor be more effective? Thanks.

This should work as long as you have a fairly decent hammer drill. I have discovered that it is best to use a smaller bit such as a 1/4" or 5/6" They seam to drill faster than a larger bit. Also, when you purchase your masonry bits make sure they are percussion bits.

It would probably be best to spend a few bucks to rent a heavy duty rotary hammer drill. Would drill much faster and hold up better.

A standard hammer will probably burn up on you.
