Hi All,

I was nearly tempted to get one of the impact screwdrivers as
mentioned here a while back but I couldn't really see a need and
wasn't sure how / when I would use it?

Every time you stick a screw in basically. (also leaves you drill free
to have a drill in it without continuous bit swapping)

It also looked like it was a hex drive and so limiting what sort of
things you could drive with it (compared with a chuck)?

Yup, although if you really want drill bits with hex shank you can get
them.

At the market yesterday I picked up a set of hex drive to square drive
adaptors (1/4, 3/8 and 1/2") with the thought of using them in my
Stanley Fat Max cordless impact drill (on speed one) as a form of
electric nut runner (mainly for removing machine screws / nuts) and I
wondered what the RW difference would be between that and the impact
driver?

Max torque on the drill will be significantly lower. Many 18V drills top
out at about 60Nm, and 18V ID will do north of 150Nm (although for
comparison a full on cordless impact wrench will usually do several
times that). Also the rotational impact action can be better at freeing
stuck fastenings than continuous torque.
