The nut driver that I posted about was for SDS+ drills. Adapters
probably don't exist for the larger size of drill that you were trying
to rent.

I'm pretty sure this one is SDS+. I tried to call them back to find out
for sure but they were closed. I'm going to find out today.

You're still thinking too big, Rick. "A bigger hammer" is not always the
answer.

Right, but this is the only one I've found available for rent, so far.

NOTHING will drive a ground rod into solid rock, for one very simple
reason: a ground rod is not a rock drill! No matter how hard or how
often you hit the thing, it will either bend like a bow or curl up at
the point.

Bending like a bow is OK with me. I knew up front that there was no way
to drive it in straight down, so I drove it in at about a 45 degree angle.
If it hits a rock and bends, that's OK, at least it will all be in contact
with the earth.

If I can find the socket adapter I'll rent this one and see how it goes,
like I said the worst that can happen is I'm out $60 plus the cost of the
adapter.
