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?

Use a carbide tipped router bit or you probably will burn your stock.
