I initially bought a cheaper all metal adapter, not DeWalt. Then I thought, hey, come on. It wouldn't hurt to have two in case the first one breaks. The DeWalt is slightly longer, bulkier, and has a plastic head instead of metal. I hope it holds up over time. But I was a bit puzzled when I saw the "MAX" hammer, which was partly made of plastic. It didn't inspire confidence. But let's see.
