Cutting tool for a tunnel boring machine and a tunnel boring machine

Abstract

In a cutting tool (106) for a tunnel boring machine, a tool head (115) equipped with at least one wear sensor (315) is present that is detachably connectable to a tool holder (206, 321). A line arrangement having a wireless, connector-free coupling module (312) between the tool head (115) and the tool holder (206, 321) is provided for connecting the or each wear sensor (315) to an evaluation module (330). In this way, in the event of wear, a tool head (115) to be replaced may very easily be removed from the tool holder (206, 321) and a new tool head (115) may be connected to the tool holder (206, 321) very easily and in an electrically safe manner. A tunnel boring machine equipped with at least one cutting tool (106) of this type is thus operable in a very efficient manner.
