    I've used them quite a bit. Sure beats buying slitting saws and such....Of course, I did have to make an arbor for the ones I have...
    Feed it slow, or it'll start shedding teeth, though. And lots of lube...

    I've even sawed through hot and cold rolled steel with mine.

    Den, here's a pic of mine; it works great! It has a homemade arbor with a 3/4 shaft. I just used it last weekend and kept going up on the d.o.c. and speed. I stopped at .5 in @ 800 rpm in 6061 in my little X3. Much better than any of my regular slitting saws. Mine is 3 3/8 dia and it looks like it has the FTG grind you refer to. I haven't used a 'normal' slitting saw since getting this one over a year ago.

    I've used ordinary Skilsaw blades to cut Al on the Mill. They work great. Just do the math to get tip speed right for the metal you are cutting.

    Makes sense
    [pedant]So it's really FT grind ?[/pedant]

    ISTR there was a thread about this a while ago, not tried it myself.
    What's FTG grind?
