Yup, it's the Hilti TE-76-ATC.

Nobody I ever heard of... but it sure works nice.

Thanks, Rick - - I guess if you knew the part number for the "right fitting"
you would have told me. Can you describe what it looked like?

Yeah, I have no idea what the part number is, there wasn't one on the
fitting. It has an SDS Max (that's the next bigger one than SDS Plus,
right?) shaft that goes into the chuck of the drill, then that is fastened
to a sort of a cup fitting that fits over the end of the ground rod.

Rick,

I see on Hilti's web site he TE-76-ATC, and its accessories include a TE-
Y driving shank and a series of adapters TP-TKS ground rod driving
adapters for different diameters.

Hilti BTW are suppliers of expensive quality tools to the construction
industry, you probably won't find their tools in home handyman stores.

The tool you rented is a little lighter than the one I used, and that is
probably why driving times were a little longer. My Hitach PH-65 machine
with home made driving adapter will drive a 16mm diameter 2.4m earth rod
into dry clay in less than a minute.

Pleased it worked for you. It is the way to go, isn't it!

The numbers above might help people looking to rent a device.
