Homebrew PCBs

Why would fiberglass dull blades any faster than yellow or red brass or 
any other metal for that matter?

If you want to cut boards on a tablesaw, I would recommend a plastics 
and phenolics ready triple chip grind neg rake blade such as this one

For cutting PCBs are other plastics I use a Freud Diablo non-ferrous cutting 10" blade on a table saw (carbide, 80 tooth as I recall) it has a very interesting tooth profile and a low, if not negative "hook".  Cuts plastic and aluminum plate like butter...virtually no burrs.
