Over at Facebook, Casey asked whether these SDS to socket adapters would work well with his Dewalt rotary hammer (that new brushless one), for breaking free hand-tightened lug nuts that his compact (low torque) impact wrench couldn’t loosen.
I don’t have any experience with these adapters, which are used an SDS rotary hammer to turn sockets.
I don’t think that using a rotary hammer would be much help in loosening stuck lug nuts. It just doesn’t seem that there would be enough impact energy transferred via a socket, unless maybe you could somehow bottom out the lugs, but I still don’t see it working. Am I wrong?
Update: Check out comments to see why hammering on lug nuts is potentially a very bad idea.
Casey mentioned seeing reviews by people using their rotary hammers to drive in rebar, and I remember seeing similar mentions or recommendations over the years. They’re also used to drive in grounding rods and other similar shaft-like materials.
I suppose that, with these adapters and appropriate sockets, a rotary hammer could be used for driving in Tapcon wall anchors, or other such fasteners, when in rotary-only mode – in a pinch.
As Steve mentions in the comments, you don’t have any torque control, so you would have to be very careful to not over-torque anchors or fasteners. Tapcons, for example, strip out their self-threaded holes if overtightened.
If you’ve used SDS to square drive socket adapters, how’d they do?
And if not, well, at least you’re reminded that they exist.

These adapters are offered by Tonsiki and a dozen other brands I’ve never heard of, for around $10 per 1/4″, 3/8″, and 1/2″ set.
