Brian, I am planning to do a wood burning stove but I figured on using a jigsaw to make my holes through the exterior wall. The stove pipes I planned to use were single wall from the stove into a insulated through the wall transition to a double walled stainless. I think by tracing the diameter of the pipe on the inner wall and the making a pilot hole through the center to the outside I could do a decent job with a jigsaw. Consider alternatives.
I won't take credit for these suggestions since I read them on another site having to do with this exact problem. First was to drill a 3/4 " pilot hole big enough to allow for a long sawsall blade to finish the hole. Next was to use a 6 1/4/ 6/1/2" self feed bit which you are looking for and use a small chainsaw to plunge out the rough material inside. Could you use a small chainsaw to plunge cut a square opening and then use a filler to seal and flange to finish?
