I know don't do it.

But I was planning on drilling a pilot hole though a wall. Then replacing
the pilot drill with a long metal rod, so that two pilot holes would keep
the rod straight.

I'd have to replace the first pilot hole I drilled out, so That I still had
two when drilling the other side. Hole size is 5" and material is drywall on
one side and some kind of fibreboard on the other.

Anyone tried this?

If you're talking about a fly cutter, then I'll be proud to nominate
you for a 2007 Darwin Award (Woodworking Division).

If you're talking about a hole saw, then you may be able to use some
type of drill guide with a long bit to drill both pilot holes.

Yup... let's mount a bar with a sharp end onto a bigger bar with an
attachment and mount the whole contraption and spin the sucker at 300
(the usual minimum speed on a drill press) and then feed it into a
piece of material, which usually isn't clamped down and sell the whole
killer tool combo for $ 9,99 to the great unwashed, who don't have a
clue.
People who SELL those things should be liable.

Better yet... let's screw one onto a radial arm saw!!!

Are you serious about this? That sounds too wierd to be true.

It's true, I had one. I think it came as a freebie with something
else. As I recall it went directly into the trash.

I do! I do!. I would describe the blade as shaped like a shallow bowl or
like the bell found on a fire alarm. It usually required removing
or modifying the circular saw guard to be mounted. By varying the depth
of cut and bevel angle of the saw, curves of different radius could
be cut.

Had forgotten it till you jogged my memory with your post.

Got some swamp land in Arizona to talk about if you are a candidate for
a triangular saw blade.grin

I am assuming here that you are talking about using a shallow can-shaped
holesaw. They almost always use a 1/4" drill bit for a centering
device. You certainly should be able to do exactly what you are
talking about, considering your medium is drywall.

Drill a pilot hole thru both sides of the stud cavity .. .. replace the
drill on the hole-saw assembly with a 6"-7" piece of 1/4" smooth rod ..
... place the 1/4" guide now attached to the hole-saw thru both guide
holes, and drill away. A hole-saw will NOT be any hazard used in this
manner drilling an aligned hole in drywall. People do it all the time
for dryer ducts, dust collector ducting, etc.

Bill, Bill, Bill. You you already say you know not to do it. So
why do it?

Something like that, that you've obviously thought out, you "never"
ask if you should do it or not. What I'd do is, go ahead and do it,
then post about it. Think I'd have ever got anyone to say using my
power planer on a piece of wood in my runing lathe? I don't think so.
But it worked great, altho it did take wood off a lot faster than I'd
anticipated. Sure worked find for rounding off a sliglyly of balance,
square chunks of wood.

For what i's worh, I think it'd work, and I'd be willing to try it,
if I needed a hole drilled. On the other hand, I beleve one of my hole
saws is about that size, so might not need to.

another slick approach is a rotozip- or just buy the rotozip cutter
and use it in a laminate trimmer or small router. set it up with a
circle cutter/ trammel base and have at it. it'll do a very nice job
on the drywall and fiberstuff, but not the studs.

You mean one of the "fly cutter" type circle cutters?

I tried that freehand, once. It didn't work out too well.

I'd think that in drywall, which is quite soft, the pilot would enlarge
the pilot hole as the cutter imparts a lateral force on the pilot (you
can easily experience this by chucking up the cutter in your hand drill
and spinning it at low speed). It might be less of an issue with a
smooth rod, but I do think it would be a problem.

Can't you find a hole saw the proper size?

Hoe Depot sells a circle cutter designed for installing recessed
lighting fixtures in drywall ceilings. But the Rotozip/trammel
approach is also viable. I suspect your concern is to get the tow
openings parallel one to the other (hence the idea of drilling the
pilot hole through both surfaces in one go. If you use th trammel
approach, this "one go" pilot hole should serve, but it might be
better to use a smaller (1/8") bit unless you can replace the little
RotoZip Trammel guide pin with a 1/4" guide.

(as someone else commented) Let us know how it goes.
