The aluminium sheet is 8mm thick, and I plan to run the saw in a large pillar drill and use a slow speed, gentle pressure and lots of lubrication. (hehe, sounds quite dirty) Will that work or will i just screw the saw up? Thanks.

it does not center correctly leaving a lip on one side. i also tried a 5/8 hole saw and adjusted the notcher still off center..any tips appreciated.

When I use the hole saw with the teeth in a more aggressive "forward" position, they grab and it jerks the drill out. When I reverse the drill I can keep the saw in the hole, but it barely cuts at all. This is a piece of 5/8" siding I'm trying to cut through if that makes a difference.

i need to install a reverse osmosis water system for my apartment. but i need to make a hole for the faucet and tap the water pipe for the tubings. where can i rent these tools in chicago? can i go to home depot or ace hardware or something? i already got the ok from my property manager ...so i can install. i just have to replace the pipes whenever i move thxs for all of you alls help
