Often on Holmes Inspection and This Old House, the workers use what appear to be

Impact driver. Yes, I suppose it is a bit like a hammer drill. I've
not torn mine apart yet to see what is impacting, but they sure make
Tapcons, lags, and Phillips screws work wonders.

Here is some information: type "impact driver" in google. These things
are all the rage, but it would be the first tool I would replace if lost
or dead.
