Trimming Router Bits

Cut layers of material flush to one another or make cuts along a template.
Use carbide bits for longer tool life and faster cutting speeds than high-speed steel. Micrograin carbide bits provide superior wear resistance, long tool life, and a cleaner finish than bits made of other materials. Ball-bearing pilots guide the bit for accurate cuts and produce less friction than solid pilots for smoother operation.
Pilot location describes the position of the pilot when the bit is used for hand routing. The pilot location is reversed when using the bit with a router table. Bottom-pilot bits trim material from an upper layer of the workpiece so that it is flush with the layer below. In addition to flush trimming, they can be used to cut along a template placed below the workpiece.
Bits with straight flutes are for general purpose use. They quickly remove material, leaving a rough finish.
Choose a bit with one flute for a faster cut; bits with more flutes produce a smoother finish.
Bits with an overhang cutoff edge remove most of the excess material from the edge of workpieces such as countertops and sink cutouts, but they leave some material leftover for precise trimming after the installation. This process minimizes the risk of chipping laminate during installation and produces a clean, professional finish.
