Again, if you use one of those, make sure the work is well clamped and use slow speed. I also have one and seldom use it, preferring a hole saw that gives you 360* contact on the work piece. You also might find that on 'glass that you could have more chip out especially if one of the cutters is a bit dull.

IC2, I have that concern, too, especially thinking about the imbalance of my single cutter unit. I'll go back into town tomorrow and see what kind of 360* hole saws I can find, knowing now that I want to cut a bit small and sneak into the final size. I figure I can cut a test hole in wood, and "tune" the saw a bit with a flat file & drill press if it is cheating big. When I stopped in Saturday I was looking for exact sizes.
