I've also heard of people mounting the blade backwards so the teeth face
away from the work to cut aluminum. Not sure how this helps, but others
say it works.

Perhaps I should have said 'backward' rather than 'reversed' as the latter
may imply reversed rotation. Mounting the blade opposite to its normal
orientation is what I meant and that has worked for me on light gauge
metal. For thicker Al and brass, I have used the dremel slitting saw
method.
