The normal carbide wood cutting saw blade does a fine, safe job
cutting non ferrous metal. I've use it for aluminum, copper, and
brass. Steel requires a different blade - I've used Tenryu, DML,
and Morse. The steel blades work better with a slightly slower
RPM, but will work on a worm drive.
The aluminum will still require a bit of filing or sanding, the
result is not a smooth cut, but much faster, cleaner, and safer
than fiber blades.
