If you have no other way and need precise vertical hole, dremel make s drill press attachment.

I have one (gift from inlaws) and a real drill press which is what always gets used for holes. I also use the AC verison of the dremel.

He already has that...




You'll be fine drilling with the dremel, and better off if you can use that press attachement. I've been considering one of those... Carbide tipped bits are definately the way to go, and just take it slow.

Didn't see that, please forgive my oversight

You don't need carbide tipped bits to drill alum, waste of money unless you going to drill something thats hardened. High speed steel drill bits will be more than enough to drill alum.

Don't need highest rpm either. Use medium RPM and feed it at a rate that generates good cutting. If its not 7075 alum, the cuttings will be long pieces at optimum rpm/feedrate. If its 7075, they will be smaller, but clean distinct pieces.
