I have occasion to cut baseboard flex moulding. It is urethane, dense

answer. "we use a spatula", but any blade will work....

I found plenty of info about material and blade selection, but nothing
specific to urethane (6" flex baseboard).

Using 60T or 80T blades.. this stuff kills my 12" miter saw blades. It
has become the last material cut

Any suggestion on a blade type, tooth count, or a better type of
blade? Mine are all ATB blades.

Look for a triple chip grind with no more than 5 deree hook,0L degree
hook angle would be optimum, anywhere from 80-100 teeth should do
well for that saw.
ATB blades just don't last so long in plastics which tend to be
abrasive.
There are also special grinds for plastic very similar to a tcg with
the usually straight tooth also having eased corners but I doubt you
will need one for this application.
