Gary many of the big names hammer drills have the ground rod adaptor. The trick
is to find the rental co who has them both. I use to use a home brew dual
handled piece of 2" od 1/2" wall X 36". But scraped that when I found about
the Hammer drill routine .
I put in 26 8' roofs in a four hour rental So I second the use of this tool.
