I know this has been covered in other threads, I did a search through the archives. I'm looking at Hilti demolition hammers, but would really prefer a combo unit in case I want to core or drill. For the price of these ($1200-$1450) I'd like it to do more than pound ground rods.

The soil around here (swampland, Illinois) is better than Arizona. I can get a ground rod in with a 4 lb. hammer in about 30 minutes when it's tough. I don't know how anyone uses a sledge. I'd probably miss the rod & hit my leg. I may also opt for the cheap pipe with sledge head welded on.

So the question is what model do you have, how is it holding it 8' up with ground rods? If you use it for drilling or coring, what size holes, etc.? Any info would be greatly appreciated.

I've never used these before & its about triple what I usually spend on tools. I want to make sure it will be my new best friend.
