I've just tried the SDS drill a couple of times, and the first time it went in an inch and then stopped. The second time it went 4 inches in and showed no signed of creating a split, so I stopped.
On both occasions I had to use the wedge and hammer to free the chisel bit from the wood.
So, nope, it doesn't work. One would need a very powerful pneumatic jack-hammer with a bit designed for splitting wood.
So, back to using my feeble arms & shoulders - trained on computer keyboards for decades, not sledge-hammers! :-(
"Ooh, me back..."
