I need to drill a hole 1" in diameter through a 3" X 3" X 10" piece. It has to be close to center and 10" long. All my 1" bits are 5" or less in length. I know, I can drill it half way, then turn it over and drill it again, but I'd like to do it in one pass. I've got 20 or
30 of these to drill at the same time.- posted
