The message
from "Dave Plowman (News)" contains these words:

I see these in the Screwfix catalogue, Impact Drivers. Anyone know what
that is? Does the drill hammer? Is it just a drill/driver without a
chuck? What is the advantage? Also, Drywall Drivers, also in Screwfix,
what do they do over a drill/driver? If a tool can save me time, effort
and produces a better quality job, then I am always interested.

An impact driver is usually a screwdriver which can take a variety of
bits
or sockets and has a cam mechanism within. It's purely mechanical. You
engage it on the screw or nut and whack it with a hammer. Most commonly
used on cars rather than houses.

Until drivels brother posed the question I thought such information was
common knowledge. ;-)

seems half you lot are confusing two very different tools, and the intended
use.

since the OP also asked about Drywall Drivers its reasonable to assume the
former.

Wow, what a thread when I came back. A good assumption, I did say
drill, so it was the power drill. Thanks for all the links and
explanations. If my drill/driver can't cope with large screws, then I
use a mains drill. That always does it. These impact drivers appear to
have the ability to ram in heavy screws without pilot holes all in one
go. That would be handy and save me time too. They sound good. When the
drill driver goes west I will definately go for one of these "impact
driver drills".

A cheap drywall drill would be handy, as I consider that a luxury, as I
don't board up all day.
