Trimming a workpiece to size using a router bit with a bearing fitted and template is the easiest way to get a good smooth finish. The cutting action of a spiral bit makes this job easier on the router, and leaves a better finish. These two flute solid carbide spiral bits have two ball bearing guides. Great for use where chipout is a concern with plywood, melamine or other laminate surfaces. These upcut bits are for use with handheld router applications.
