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.
If it looks like a miniature grease gun, its a thing you put a bit of
some sort in the front, hold firmly over a nut or screw and whack very
hard with a hammer on the large end.
The wack is converted into rotary motion and combined with the force
of the whack, frees the nut/screw. ( you hope)
That is exactly what I would have said an impact driver was. Probabley
the very first tool that I ever bought 40 years ago as it was
absolutely essential to get the very tight screws of a motorcycle
engine.
