Improvements made to a router relate to a router chuck and collet mounting system. In a preferred embodiment, the present mounting system comprises mating a top face of a router chuck with the lower surface of an inner race of an armature shaft bearing and mating an inner diameter of the chuck with an outer diameter of the armature shaft to align the chuck with the shaft. Additionally, a cavity through the chuck may be used to accept a router bit shank so that it extends up into a lower end of the shaft in order to permit the shank to extend upward, closer to the armature shaft bearing. This arrangement reduces router bit run-out.
