Abstract

The cutting ring (201) can be moved along the roll hub (200) in the axial direction. An Independent claim is also included for a method for increasing the diameter of a tunnel using a tunnel boring machine with its drill bit modified to take the above cutting roll (20), in which the drill bit is first of all fitted with a first cutting roll to increase tunnel diameter to a first size and then fitted with a second cutting roll to increase tunnel diameter to a second size.
