Do you have a (motorized) scroll saw? I can use the same blades on
mine as on my jeweler's saw. (But not vice versa -- the jeweler's saw
only takes pinless blades, the scroll saw accepts either pinned or
pinless 5" blades.) I've cut lots of wood, paper, and plastic on my
scroll saw, typically with a 15 or 20-tpi blade, and small amounts of
steel with a 40 tpi blade (0.012" x 0.022" cross section). The steel
was 1/20" sheet and I advanced it only about 1 IPM with the saw running
at about 600 strokes per minute, which gave a milled-looking cut surface.
With thicker metal, heavier blade, and higher SPM, you might be able to
race along at 2 IPM!

The short answer is no. I considered buying one and asked around about
its performance on steel. The consensus was that for 3/16" plate it
was a waste of time, money and a lot of blades.
