That is my experience of them (but not with my Fat Max drill etc).

Have an ancient B&D screwdriver, has a gear box between motor and bit
drive and gives plenty of torque. The trade off is that it doesn't
spin things in or out particulary fast. It's still quicker and easier
than a manual screwdriver. As the gear box locks when not driven by
the motor it also makes for a very powerful, by virtue of the large
grip, manual screwdriver as well.

Don't use the ordinary drill/driver to drive screws. The control of
speed and torque is far too tricky. Give it enough "go" to get a fast
drive, when the screw gets tight the torque shoots up as the motor is
stalled and the bit chews the screw head or cams out and bounces
across the work...

Can you get a linear screwdriver style impact drivers or are they all
pistol grip type things?
