ECN Forum Forums General Topics of the Trade General Discussion Area Hammer drill for driving ground rods

HILTI TE-76, the best there is!

Not sure about you guys in the US, but up here we use the ground electrode plates instead of the ground rods. Sooooo much easier. We get the GC to dig the hole with one of the machines on site. Or, if necessary we dig by hand.

Are ground plates allowed under NEC rules?

***edit*** I realize that you guys may be talking about ground rods as required for grounding xfmrs. If so, please disregard my post.

I use a Milwaukee "Thunderbolt" spline drive hammer drill with a homemade ground rod driver attachment.

Big improvement over a sledgehammer.

Cost me about $450 3 yrs ago with 3 drill bits,and 2 chisels.

If you can find one try using a kango demolition hammer. I am probably one of 5 guy's on this site that know this but there is not a better demo hammer made period.
