Yeah that's not a bad blade to have if you’re doing a lot of fabricating. The saw it self is just a woodworking chop, the blade will work on any brand chop saw. Evolution also has a compound version for about a hundred more and that feature would really come in handy if you were fabricating frames, suspension, roll bars etc., where you needed different angles.
Those blades run just under $100 and they claim they will make 750 cuts in 2" box tubing.
Those blades came out a decade or so ago, I've used them mounted on a Skill saw also, scared the bejeebers out of me the first time. But they will cut thru 1/4" alum plate like it was butter. Then again I've cut the same aluminum plate with a carbide blade mounted in a Delta table saw, you just had to be careful feeding it so you didn't chip the carbide.
I never tried cutting steel plate or solid bar stock with those metal-cutting blades. I don't imagine they would last very long cutting plate or bar stock or any heavy steel as far as that goes with out a coolant. The cut shop where I worked had an industrial strength chop saw dedicated to cutting bar stock but it was set up with coolant.
If you have a chop saw for your wood working then just buy the blade for $100 and don't try cutting anything real heavy in it. But it would work great for your tubing projects. At home I would still stick with the horizontal band saw for solid stock.
