Of course, there are some who clean the carbide and touch up the faces with
600 diamond file prior to routing, and sometimes during long runs. Process
is exactly the same as your HSS.

Carbide is needed to prevent burning? Would you care to elaborate on that?
Of
course you realize that, although it will hold an edge longer, carbide is
more
difficult to sharpen, and HSS bits will often take a better edge. That at
one
point, having trouble with some burning on a particular piece of cherry, I
switched from carbide to a freshly sharpened HSS bit and eliminated the
burning. And you know that the combination of speed, feed rate and depth
of
cut will have the greatest influence on burning. So, given that, what's
your
point on carbide?
