1. A router comprising:
a motor unit including a motor and a spindle configured to output a torque supplied by the motor; and
a base configured to selectively receive the motor unit to support the router on a work piece surface, the base including
an input shaft configured to selectively couple to the spindle, the input shaft including a first pulley;
an output shaft laterally offset from the input shaft, the output shaft including a second pulley and a tool holder; and
a belt wrapped around the first and second pulleys to rotationally couple the input shaft to the output shaft; and
an adapter bit configured to attach to the spindle and configured to couple the spindle to the input shaft, the adapter bit including a first connection member and a threaded bore that threadably receives the spindle;
wherein the input shaft includes a second connection member that engages the first connection member to couple the adapter bit to the input shaft; and
wherein when the motor unit is received into the base, the spindle couples to the input shaft.
