I have a 4" and a 6" diameter hole saw from Vermont American that are supposedly capable of cutting sheet metal. At least the packages indicated that these could be used for wood, fiberglass and sheet metal. I have smaller hole saws that should not be used on sheet metal though, I can't recall the brand names of these. ---------------- Bill Gallik E-Mail: [EMAIL PROTECTED] - "Nothing changes your opinion of a friend so surely as success - yours or his." - Franklin P.
