What is the best and cheapest way to drill twenty 1/2" holes through a standard slab floor, probably 4". Some of the holes will be drilled at a slight angle.

Just a though. I once worked for a retail store. They built a new building at a mall. It was the only building in the mall with a basement. Someone decided they needed to drill a hole in the floor for some electrical work. Did I tell you the mall was built on an old swamp. They drilled the hole and ended up with at 12 in fountain. It took them several days to get that patched up.

My house is not on top of a swamp. However, I may get the same "fountain effect" when/if I hit a water line under the slab. :(

After many hours of trying to drill a couple of holes and going through many drill bits, I purchased one of the SDS type masonary drills at a Harbor Freight store for about $50 and the drill bits (special type) were about $12 for a pack. This setup goes through concrete like a knife goes through butter. It's not commercial quality but it works. No more standard masonary bits for me !

As some have mentioned here before: ...avoid the re-bar....
If your "standard slab floor" is like mine you certainly want to avoid a "tension cable" in the foundation if you "happen" to have one.

Paint a really good rendition of an Iranian Tank on the roof, and convince a passing A-10 pilot to shoot at it for about
1/10th of a second.
