I am using a 4 inch hole saw on a Wen 10 in variable speed table top drill press. I want to keep the plug that comes out of the hole saw and don't want a hole in the muddle of the plug from the arbor it. I have my workpiece (1/4 inch MDF with walnut veneer) clamped down at multiple points. My RPM is 600. I have had some luck with no arbor bit, but I have ruined a lot of pieces as well. I need 60 plugs. I have used Diablo hole saw and Hole Dozer hole saw. IT seems that both of these have a good bit of wobble (the drill press is fine). My questions:
Am I crazy thinking I can get away with a 4 inch hole saw giving me a clean cut plug with out an arbor bit?
Should I expect 4 inch hole saws from Diablo and Milwaukee to not have run out? Because theya re very wobbly. My drill press runs true. chuck is good. other bits are fine, and smaller hole saws dont have as exaggerated of a wobble.
