I have a blade for fast rips in hard wood that performs well, within
it's parameters. it has maybe 20 teeth, flat top. it never burns, but
the edge it leaves needs to be surfaced- plenty of visible tooth marks.
for roughing out in thick hardwoods, it's great. it cuts fast, almost
no effort to push 3" thick oak through it. I forget, but I think it's
either amana or wkw. I think wkw.
if you need a better cut, the blade will likely have other than a flat
top tooth configuration. and be fussier.
have you contacted forrest about the performance you're getting with
the blade you have? their service is supposed to be pretty good. they
also make blades closer to the configuration you're looking for.
bottom line is that matching the right blade to your application will
make it go faster and better, which means you save money. the cost of
the blade is insignificant in the long run. don't be afraid to try a
few blades to figure out what works best on your machine, in your shop,
by your operators, in your materials. there is no magic one blade does
everything best solution, forrest junkies notwithstanding.
