I'm very happy with my Infinity Tools Miter Max
12" 90 tooth blade. I don't see much room for
improvement in the smoothness of the cuts. With
a 5 degree negative hook it's ideal for a sliding CMS
and it's on sale from time to time. Infinity is about
the only company I buy any of my blades or bits
from anymore because of the great prices and, in
my opinion, unbeatable quality.
