build a small deck. Of course, every new project requires a new tool,
right? And my trusty Bosch cordless drill is showing its age a bit, or
to be more precise, the batteries are showing their age -- building a
deck, I'll definitely drain the batteries in much less time than it
takes to recharge them. So I'm looking at other options,
including compressed air drills (e.g. saw one at the Borg this evening
for $45 or so). But I got to wondering... almost every cordless drill
has a multi-position clutch to prevent overtightening, or sinking
screws too deep. Does anybody make an air drill with such a clutch?
Despite what others have been saying I have recently bought an air
impact driver. Of course as with any tool you get the quality you pay
for. Although as far as I know there are few really cheep quality air
tools yet. For me the advantages are clear 1) there are no
batteries that will die if not used for a months and any way in about 3
years. 2) Smaller than any battery impact driver.

Nonsense. Have you looked at a Bosch Impactor? Any smaller and it would
be useless.

Of course it it small however it is also low powered. Size for power air
wins every time.

So you're saying that an air impact driver with a power level
appropriate to driving deck screws is necessarily too small to be
usable? Because that's what it sounds like.

3) The air hose is far more flexible and longer than any corded driver.

Again, nonsense. How long is a string?


nonsense? Not at all.

cables for a corded driver are almost never over 3M however since all my
air tools have a QR on the tool. Any length (in my case) up to 50M
without junctions is usable.

Don't they have extension cords in your universe?

4) The service life is much longer than any electric powered drill.

More crap.

In your opinion.

If electric impact drivers were so good then tyre shops and garages
would use them.

Tyre shops and garages have to remove stuck or rusted on fasteners, not
drive deck screws.

Try driving deck screws with one of the impact wrenches that a garage
uses and get back to us on how you make out.

With sanders exactly the same is true though they need a high airflow,
so few non professional workshops have the compressor power to use them


5) Over haul when eventually needed is it is easy and fast

Only because it needs it.

Which part of the word "eventually" did you miss?

by the time an air impact can use an overhaul it will have outlasted 2
or 3 equivelent electric impact drivers

By the time my electric impact driver wears out in the use I give it my
grandchildren will have inherited it.

You seem to have some kind of religious devotion to pneumatic tools.

If you can find a pneumatic tool purpose-designed for driving wood
screws please do provide a link to it.
