Abstract

Apparatus for rotary boring in the surface of ground formations with a boring head having several cutting rollers mounted in bearing elements and a drive shank which is provided with wear projections. In order to simplify the replacement of the bearing elements and the wear projections at the work site, means are provided which enable these parts to be welded at the boring head or at the drive shank without previous preliminary heating.
