Abstract
The router bit includes an upper and a lower cutter, axially aligned and separated by a fixed longitudinal displacement. No substantial portion of the bit extends beyond the lower end of the lower cutter. In some embodiments, the lower cutter may be configured with bottom face blades to allow the router to be used as a plunging bit. The cutters may use wing blades or spiral blades. The portion of the bit intervening between the upper and lower cutters may also be configured as a cutter. In some embodiments, the router bit is integral. In other embodiments, it comprises separate elements that may be axially secured.
