A tool for gaining lateral access to a well includes a head portion configured to advance axially forwardly relative to a lateral access passage. The tool includes a first shaft and a shaft assembly including a second shaft. The second shaft is at least partly received in the first shaft so as to be axially forwardly moveable therewith. In use, axial forward movement of the first and second shafts causes forward advancement of the head portion. The second shaft is axially forwardly moveable relative to the first shaft. The first shaft includes an internal thread and the shaft assembly includes an external thread engaging the internal thread of the first shaft so that relative rotation of the internal and external threads causes the axial forward movement of the second shaft relative to the first shaft without rotation of the second shaft relative to the first shaft.

A convertible power tool that can operate in first and second configurations. The tool includes a base unit configured to receive at one time either a first module or a second module. The different modules provide for different levels of functionality. The first module includes one or more components that provide for a first level of functionality. The second module includes one or more components that provide for an advanced second level of functionality. Each of the base unit and first and second modules may include interfaces that provide for physical engagement as well as power/data engagement. In use, one of the first and second modules is connected to the base unit to provide for the desired functionality incorporated with the tool. The tool may also be reconfigured by removing the attached module and replacing it with the other module thus providing for a different functionality level.
