I cut metal all of the time on my 10" Delta Contractor's Table saw. I use blades from my 14" chopsaw that have worn doiwn to about ten". I use some of mine and also a supply that I get from a friend who has a machine shop. My table saw has a 1 hp Dayton motor with a belt drive at 3,450 rpm.

It will cut most any thickness of metal up to 1/2". I use it mostly for long cuts in 1/8" sheet. Of course, you need a face mask, gloves and long-sleeve shirt to be safe.

I blow the saw off now and then to keep it clean. It willl still cut wood nicely whenever I want.
