Abstract

A drilling tool for enlarging previously drilled horizontal bore holes. The tool has a guide surface forward of the drilling means to engage in the previously drilled hole and a stabilising surface behind the drilling means to engage in the larger hole to support the drilling means. The guide and stabilising surfaces may include ribs, helical ribs, rings or rollers. A mud motor may be placed between the drilling means and the stabilising surface.
