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.

Of course Screwfix may mean something else - if so a reference would help.
