Apparatus for mounting a drill on the pipe comprises a platform (9) carrying a mounting member for a drill stand (37). The mounting (37) may slide along a frame (25) which carries a plurality of elongate holes (35) therein. The longitudinal movement allowed by this relative sliding permits a drill (51) mounted on a drill stand (43) to be selectively positioned in order to bore a hole in a pipe (7) upon which the platform (9) is rigidly clamped. By provision of such a facility, there is no need to loosen the clamping force of the platform (9) upon the pipe (7). |
