Not sure how hard your rock is, but we had to drill a lot of holes in basalt on the current job, for form stakes, etc. I used my Bosch hammer drill quite a bit (it's a sissy SDS Plus tool) with the garden-variety bits. Basalt is quite hard but it's a lot easier than drilling old concrete.

Lots of petrified wood, but that's way too hard (too much work) for me. Anyhow, when you get something made, please post it.
