For non-ferrous metal (aluminum, brass) a very fine-toothed blade can be
used. I have one for my miniature table saw that's about 160 teeth per
inch. They're sometimes referred to as "slitting saws".

For ferrous (iron, steel) metal the abrasive approach is your only
practical option for a power saw (don't think you'll find a horizontal
bandsaw that will fit on a table). A diamond blade would be nice...
