This is the best tool I've ever bought! My wife and I are renovating our house. When we bought the house, the foundation had cracked in a dozen places. Many thought the earth was moving, so we made good money. Before we bought it I inspected it and found the foundation was only 3 inches thick and there was no grout in the block. We excavated 380 tons of hard clay with this demo hammer. We move 18,000 5 gallon buckets. I think for this tool that breaks this tone we could not succeed. We now have new solid basement walls and foundations as well as a full basement. I have lent this hammer to several friends. day and bought it.
