Before we can get into how to use a bullnose router bit on your piece of wood, let’s discuss what a bullnose router bit is first and how it can be used on a handheld router. 

A bullnose router bit is typically used on a router to make curved types of edges with ease and accuracy in comparison to a round-over bit and a beading router bit. The shape of bullnose edges can be used for making bead profiles in woodwork, dividers on draws and other woodworks which require smooth edge cuts. 

The router bit can further be used for making impressions in stone and other building materials where you need curved edges.

In comparison to a roundover router bit, they also allow you to have a completely smooth edge in curved pieces without an annoying flat spot at the top of your edge radius due to their style of cutting.
