My dad had a TE54 sent down to me. It's been used, but it still works. I'm wondering how many of you have used the TE54, and whether or not it can handle driving 5/8" ground rods. I realize it depends on the type of earth/rock you're driving into, but I'd like to know how the tool fared. What are it's limits (what have you subjected it to) for drilling? I plan on buying a rod driver attachment right away, but don't want to waste my money if the tool can't handle the job.
