The spindle that goes in the middle, and connects the hole saw with your
drill. It also has the pilot drill in it.
Yes.
Depends what the material is. You'll need a 13mm chuck.
While I'm usually pretty relaxed about handling asbestos, you should be
aware that cutting it with a holesaw will produce *huge* amounts of
dust. Unless you fully understand the precaustions you need to take,
don't do it.
It's a very hard material to cut, so will take you a while to get
through it.
Also, I don't think you'll get away with using your 2 speed, you'll need
a variable speed.

Only if you get a holesaw with a shank bigger than 10mm. Otherwise a
10mm chuck will do!

| Grunff replied to Lurch on 20 May 2004 |
Yes, but the only arbors I've seen for larger holesaws (~40mm+) have
bigger shanks. I'm sure you can get large arbors with small shanks, but
they're not that common.

Assuming that it is asbestolux -a mixture of cement and white asbestos
(quite soft when new but hardens with age) you should wear a good mask
but you might try drilling through a bag taped to the ceiling. Whatever
you have for a ceiling, that will cut down on the debris that flies
around.
Asbestolux is by no means as dangerous as asbestos sheets -which I doubt
very much you have. Asbestolux is smooth on one side and dimpled on the
other. Why does everyone assume you have that and not the white faced
hardboard most often seen in portacabins?

If the ceiling is hardboard, then it requires replacement more urgently
than asbestos, as it is a serious fire risk.

On the positive side, assuming one were to wish to get rid of the stuff,
we have removed all but two of the Asbestos (sounds like your "lux"
stuff, but the council man just called it Asbestos cement) ceilings in
our house. Commercial companies want to hire you a skip at some £300 to
£400 a time, but we found our local council would take the stuff away
for £15 a "wrap" where the guy reckoned our 3m by 5m lounge would take
3 or 4 wraps.
Taking it down was a horrid dirty messy job (it had been up there for
70+ years and accumulated a lot of muck, though of course we kitted
ourselves out with disposable suits, goggles and dustmasks) and
replacing the ceilings does involve a bit of cost (plasterboarding then
getting the Artexer in), but IME well worth it. The other two ceilings
are coming down as soon as we are ready to do that half of the house.
Hwyl!
