Corner Rounding Router Bits w/ Ultra-Glide(TM) Radius Bearing
This unique tool produces a true 180o bullnose in two passes. Make the first pass with a regular 1/4' x 5/8" steel bearing (optional). Switch to the Ultra-Glide™ radius bearing for the second pass. This unique bearing follows the curved surface, eliminating the flat track typical of the two-pass cut with the regular bearing. This is also called a double roundover bullnose.
