Review on DEWALT DW3984 24TPI Portable Blade by Jorge Maertz

I bought a new Dewalt portable band saw and this set of 3 replacement blades. The saw's blade lasted quite a long time, cutting 2 7/8" hardened oil field tubing. The new blade didn't make a single cut in the 1/8" and 2" angle iron before the teeth were fully worn out. Since the blade without is heat treatment, I will look for blades from other manufacturers.
