Somewhere out there somebody has a giant holesaw(or 2) that has been passed around for the past year. It may be warn out by now, but send it back to me and I'll weld on a new blade tip so we can keep it going around. The important thing is to cut slowly and straight. I did run one out the side of a muffler
(OOPS!) by not being careful with tool alignment.
