Abstract: Routing apparatus comprising a frame which at one end is connected, or adapted for connection, with electric motor drive means. The frame at its other end has an arm which provides a location for a bearing defining with the drive means the axis of rotation of a shaft having a routing cutter thereon. The arm has side faces which lie in respective planes which extend parallel to the axis of rotation and have an included angle of 90.degree. or less, and at least that part of the frame adjacent the arm and the routing cutter is confined between the respective planes.
