This may be the stupidest DIY question ever, but I want to make sure before I return it: is this non-ferrous metals saw blade faulty ? In the picture, see where one of the titanium carbide teeth seems to be too large and to extend into the expansion slot. BTW, I had made 4 cuts of 9-15" or so, in 3/16 aluminum plate, before I noticed this; it cut ok, seems like it could have been smoother, but I've never cut aluminum with a power saw before, so I don't really know what to expect.

Here is the blade:
