, and torque slip sds vs those without.

Hmm , got a dewalt sds at work with a clutch, infuriating, only possible use
is up a ladder or single handed

IMHO - the one drill that should get a lookin is the bosch sds with quick
change chuck and rotostop - just so versatile and buy once last a lifetime.
The problem is most people have never drilled masonary with sds - I used one
at work for the first time 6 years ago and it was such a revelation I had to
buy one.
