A bullnose router bit offers a more efficient way to mill a bullnose on countertops, stair treads, window sills and shelves than with a round-over bit, which may leave a small flat spot at the apex of the radius. Some bullnose bits can also be used to make bead profiles on the edges of boards. Radius size ranges from 3/32" to 29/32", to a depth from 3/8" to 1 11/32".
