Review on Whiteside Spoilboard Surfacing Router Bit by William Bell

I use this to finish a chipped CNC router plate and the cut edges were very sharp and I was surprised that all the cut edges were perpendicular to the vertical. axes and all in the same plane by 0.0005 inches! The result was a finish that performed as well as bits that cost a lot more. On passes with 40% overlap I could see NO tool marks on the very fine grain MDF surface.
