A router includes a base for supporting the router on a work piece surface, a motor housing coupled to the base for movement along a first axis relative to the base, a motor supported by the housing and operable to drive a tool element, and a cantilevered shaft rotatable about a second axis and oriented substantially parallel with the first axis and offset from the first axis. The shaft includes a first end supported by the motor housing, a second end, and a threaded portion between the first and second ends. The threaded portion is engaged with the base. Rotation of the shaft about the second axis causes movement of the housing relative to the base along the first axis.
