How can I take a 1 inch dia concrete drill bit and drill down 100' using a standard 1/2 electric drill..
I need to get through this limestone substrate.

Are you looking for a stupid answer?
Poking holes in my ideas is always welcome.
How do you plan to set and seal the casing into the bedrock so that you don't get surface water and silt into the casing?Getting through the 20' of overburden is the easy part.. I can easily wash down a 2" PVC pipe..
That still does nothing to reduce the mass. What hammer drill do you think will move the mass of 100 feet of drill steel? A tiny little hammer inside the drill won't telegraph down to the drill bit because of the mass. As I said, I worked on drill rigs and know what it takes.The weight of a rebar shaft / bit assembly can easily be overcome with a 4" x 4" gantry type set-up with pulleys. They also sell some high quality hammer drills out there that could make small work of calcium carbonate shell bedrock.
Good luck with that. This is a public forum and I can post to it even though I am a naysayer.Naysayers, go beat meat in some other forum.. I am only interested creative ideas from creative brains
