What type of bit do I need to drill through aluminum? 1/8-inch holes.
Thanks!

How thick is the aluminum?
As far as metals go, aluminum is a relatively soft metal and does not require any special drill bit.
A more important question might be how many holes are you planning on making?
If you're going to be making more than 10 or 20 or so, it might be worth the $5 investment for a cobalt drill bit.

A regular high speed steel HSS drill bit will work fine. What's more important is the speed at which you drill and the type of drill your using. A drill press at slower speeds will work best. You will want some type of cutting fluid to keep the bit cool, especially if you're cutting thicker than 1/8" aluminum.
If you' re having to use a hand held drill you might want to pick up a couple extra bits. It's real easy to tweak a bit in a drill hole and snap it off. Again, the thicker your material the more likely this will happen.
Hope this helps.
