Milwaukee 44-7/8" 18 TPI Standard Deep Cut Portable Band Saw Blade

That is exactly what the 44-7/8 inch length is for. It is a Standard Deep Cut portable band saw blade, so it is sized for deep cut portable band saws rather than the shorter compact/sub-compact models, which take a different blade length. Check the blade length stamped on your saw or in its manual before ordering, since a compact saw will not take a 44-7/8 inch loop.

The 18 TPI tooth count is matched to common materials 5/32 in. to 3/16 in. thick, and very hard materials 3/16 in. to 5/16 in. thick. Thinner wall stock than that, like light conduit or thin tube, needs a finer tooth pitch so at least three teeth stay in the cut; thicker solid stock cuts better on a coarser blade.

Most likely yes. This blade is an 18 TPI pitch aimed at common material 5/32 in. to 3/16 in. thick. Thin wall EMT is well under that, and running too coarse a pitch on thin wall strips teeth and leaves a ragged cut. For thin wall tube, step up to a finer TPI blade in the same 44-7/8 in. deep cut length.

Yes. The teeth are Matrix II high speed steel, which is a metal cutting tooth material, on an alloy backing steel body for blade life. That is the combination electricians and mechanical trades run for strut, rod, conduit and tube. Keep the stock thickness inside the 5/32 in. to 3/16 in. range for common materials, or up to 5/16 in. on very hard material.
