SDS's on low speed are great and will drive almost anything in.
That applies to any mains drill that can go slow enough. Nothing to do
with it being SDS.

Many SDS drills have their gearing set such that their top speed is in
the 900 - 1200 rpm range. That tends to be somewhat lower than ordinary
single speed drills, and closer to the low gear on a two speed gearbox
drill.

Indeed. Of course 1000 rpm is too fast for screwdriving. But most SDS are
vari-speed?

The good ones are, and a fair proportion of the cheapies. Some are still
single speed though. 1000rpm is not that fast for screw driving in some
circumstances...
