Need to install some ground rods, is there a hammer drill adapter tool
for this? really hate the sledge routine.

At the phone company, we recently switched from using 4-ft galvanized ground
rods to 8-ft copper-clad rods. I have an "official" post driver that works
amazingly well, identical to the item pictured he

When the rod is far enough into the ground that the driver contacts the
ground, I simply invert the driver and finish pounding the rod the rest of the
way (another foot or so?). After all the rods I've driven using a hand sledge
hammer, this tool is a godsend. Good luck!
