A note of caution: I believe aluminum tends to stick to the titanium nitride coating.

I just use a little bit of kerosene when I'm drilling enclosures and it stops it from sticking.

These are a good deal for occasional drilling. For serious pedal building I go for the Unibits, I like the skinny #1 that go up to 1/2". If you get the ones that go past 1/2", you can space out and make the hole too big, thus ruining your box.
