Yeah, that's the gist of it. I was half kidding about the hole saw,
but I'd give it a shot if I could find one relatively cheaply. I'm
just going through drywall, sheething and siding, so it's no big
deal. I've seen some sort of abrasive saw that's 6.875", but no seven
inchers even on google.

Even then, a 7" class A flue pipe will need 2" clearance from combustibles
so that would make the hole 11" in diameter. If he is cutting wood, he needs
a chimney fitting designed to fit into the wall to provide the necessary
clearance and to cover the gap with a finished ring inside and outside.

It doesn't make sense. A 3" flue plus 2" clearance on both sides can be 7".
I don't know much about pellet stoves, but don't they need an insulated
flue, at least 1" of insulation would give a 1" inside diameter on a 3"
outside diameter flue. You cannot be just installing a 3" naked metal pipe
through the walls or ceiling. Please clarify.

You have that right. I bought a 4 1/8" at Lowe's about 5 yrs ago and it was
$37! Choose another alternative.

First off... newbie alert. I may as well jump in though.
Most any of the suggestions so far will work fine. I've done it with recip.
saw, jig saw, and router (and dremel with a router bit). The router
requires a short piece of wood screwed to the router base and then the
other end tacked in at the center of the circle. Obviously it takes a few
passes and extra care on the final pass.

Starrett doesn't make a 7" saw, but they do make a 6-31/32" saw.
Close enough?
The sizes over 6" are for specific purposes, rather than a range of
sizes incrementing by sixteenths or eigths. Largest is 8-9/32".

The two inches around the three inch pipe is the insulation clearance
required for a zero clearance flue system. This insulation is
accomplished by inserting the three inch flue pipe inside the seven inch
through hull pipe. The two inch space between the inner and outer pipes
provides room for cool air to flow and prevent the hot combustion gases
inside the 3 inch pipe from causing charring and burning of the wall
material.

Through what material? If there are studs in the way a
reciprocating saw is likely the right too. If not a sabre saw, or
if a really clean hole is wanted, I've used a spiral saw (RotoZip)
w/circle cutter with good results.

I think he just wants a permanent hole. ;-)

Draw a line around the stove pipe and use a jig saw.

A compass, drill and jigsaw (or Sawzall or keyhole saw).

Note that it is a pellet stove. The take a 3" flue so that works out to 7".

Kidding about what? I have a 6" hole saw. It takes a bit of work to use
but it's not impossible. Check woodworking stores and big box lumber
yards. You should find a 7" saw. It won't be cheap though.

Understand; however, 7" is a long way from 6" when you're talking
about hole diameters.
BTW, 6" is the largest shown by Morse,
BTW, sure hope you have a SLOW right angle drill to handle that
beast<grin>.

Lew;
You are correct, it is a beast. Fortunately I only had to cut through
about 1" of wood. Just use a light pressure and rock the saw in a
circular motion.
