Why So Many Radii?
Q I am about to buy a flush-trim router bit. I was checking various websites and noticed that flush-trim bits come in several diameters. As all of them serve basically the same purpose — trimming one wood surface to match another wood or template surface — why do they come in different diameters when they do the same thing? Is there any advantage?

A 1/2" flush-trim bit has a 1/4" radius. A 3/8" flush-trim bit has a 3/16" radius, and a 1/4" flush-trim bit has a 1/8" radius. Forgive
