It is more likely for a project of this nature that there would be a
significantly larger volume of drywall screws than there would be 4"
screws.

Typically, one does not use 4" screws for attaching drywall.

You are guessing as usual.

Are you just being stupid or do you really believe that 4" screws are
used to fit drywall?

Matt, you must read.

An impact driver is completely unsuitable for drywall screws because
there is not the level of control required to avoid either leaving the
screw proud of the surface or pushing it right through the board.

An Impact Driver and drill/driver can be had for the price of one of those
overpriced and overrated DeWalts.

It doesn't matter what you can get it for if it's not suitable for the
job

Matt, you don't know anything about them at all, so your opinion is useless.

Impact drivers have no clutch in the way that a conventional
drill/driver does and the only controls are the amount and time of
trigger depression. This means that the operator must gauge both
accurately for every screw. This is going to become very tedious.

You get used to it very quickly. The professionals use them.

Not for fixing drywall, they don't.

Did I say use them on drywall? I'm sure they can easily drive drywall
screws though.

A screw gun gives the easiest and fastest way of putting in a lot of
drywall screws. I know, by the way, because I have done it.

Not worth it unless you are doing it all day and every day.

For 7000 screws it could be.

They are NOT 7000 drywalls screws. It ism like talking to child here.

The 18v DeWalt or a Makita 18v drill driver is the sensible purchase
for the job.

Absolute nonsense. The Ryobi Impact Driver and drill/driver

Matt, you clearly haven't a clue what
and how an Impact driver does things.

I know precisely how an impact
driver does things.

You clearly don't.

I tried out several different products
a few months ago because I was
considering buying one.

Matt, now stop porkie telling.

Although they are not that expensive, their application is quite
limited through lack of control.

You are porkie telling.

If I were installing wooden decks for a living I might consider using
one for the lag bolts. I have seen contractors using them for the
purpose. However, they don't use them for attaching the boards -
another job involving a lot of screws. They use a screw gun with a
flooring extension so that they don't have to kneel all day.

Those who have them swear by them,
and occasionally many use a small 12v
drill/driver for the odd small screws.

"The odd small screws", possibly - not thousands of them.

They also use the Impact Drivers for
drilling too, which zips through wood. Battery Impact Drivers give the
same
performance as a mains powered tool, which no drill/driver can. Impact
Drivers are also very small, which those large 189v DeWalts are clearly
not.
The 18v and 24v battery drills are "heavy" and cumbersome.

The Techtronics Ryobi product that you mention earlier weighs 1.6kg.
The DeWalt 18v drill driver weighs 2kg

Nearly half a kg does make a differnece. IMpact Drivers are also very small
with excelent balance, which at times is what matters rather than weight.

It is best you go out and buy an
Impact Driver and play with it. Another
manual under the pillow.

Already investigated and considered.

Matt? Now stop the porkies.

not worth having unless one
regularly needs to drive large
screws of different kinds without being
too concerned about accuracy.

That confirms you know sweet FA about them. The Panasonic is switchable from
Impact to drill driver. And here is what some one on this forum said about
the Panasonic, and they are available a lot cheaper from the likes of Ryobi:

for the last 9 months I've been using a Panasonic cordless impact driver to
sink screws. its great no slippage no chewed up screw heads and you can sink
the screw head just as far as you want. definitely recommended if you use a
lot of screws.
p.s. Panasonic make great tools 3 amp hour batteries last for ages and they
are small and fairly light.

no they are still pretty much the same. the panasonic has a 1/2" squre drive
on it and will undo the wheelnuts on my van no probs.
it also has a 1/4" snappy chuck to take regular hex bits. the great thing is
that instead of trying to snap screws it gently coaxes them in. even soft
brass ones. oh i think its called a multidriver. 15.6volts about £250.
worth every penny
