I keep forgetting to post new automotive tools in this section, but here is one I just got, to dig out a couple of rotten fence posts that were set in concrete. One of those posts was between a subsequent retaining wall and the fence, leaving little room to work, and the retaining wall was built about 2 feet above the previous grade, so, not only was there little room to work laterally, I had to get about 4-5 feet down to break up the concrete. Hammer drill that has a pure hammer mode. Shown with a lengthy drill bit, because depth of “cut” mattered more than anything, but I got an 18” chisel bit that worked better.
It’s narrow enough to fit, where the 20lb Makita demolition hammer that I had rented would not fit. I got the cordless just for convenience, so I didn’t have to run 100’ of extension cord. While it didn’t have the power of the Makita, it had more than enough power to chisel out the concrete.
Scooping out the broken up concrete and soil was yet another challenge, that couldn’t be solved with a power tool, and involved a few hours laying on my side, reaching down with a trowel…
