I cut about a hundred cedar signs, plus many other cedar projects a year at 12k rpm at 5ips (figuring 3/4" thick material). 2 passes. First pass is climb cut and leaves a 1/16" skin. Second pass is conventional and I cut 1/32" thru. Down spiral is my bit of choice. 2009 PRSAlpha.
Beware that even a brand new, super sharp carbide bit will leave it a bit ragged on end grain. I use a oscillating edge sander to smooth it out.
