For instance, a ¼” radius round nose bit, has a cutter diameter of ½”.

Fine Wood Working had this to say about Whiteside in their May June 2007 Router-bit review: "At the end of the day, the Whiteside and the Eagle bits had risen to the top of the mix, tying for the highest score. Lee Valley had the second-highest score, followed by Southeast and Woodtek in a tie for third. By the way, Whiteside also had the best bit when we reviewed straight bits in our August 1999 issue (FWW #137). We named the Eagle and Whiteside bits best overall. And, since the Whiteside had one of the lowest prices of the top bits, we also named it best value."
