I am planning to install an over-the-range ventilated hood in the kitchen. The stove is against an exterior wall so it should be a "snap" to vent through the rear of the hood via a hole in the exterior wall.

I haven't yet purchased a hood and will be sure to purchase one that can be vented to the rear (I think most can).

I have checked the stud location in the wall and the area directly behind the middle of the hood is open, i.e., just dry wall, insulation, sheathing and siding.

What's the best way to go?

I'd guess locating the hole on the inside drywall and then running a long drill bit through the wall at the center of the cutout/hole.

Then going outside I can see how this location fits into the clapboard siding. Assuming there are no complexities with the "lay of the clapboard" what is next, cut the hold from the outside using a drill in the corner to start a saber saw? If the hole is round, I am sure it is much larger than any hole drill I have, guess the hole will have to be cut with a "hole" saw of some type.

I'd appreciate all tips.
