ABSTRACT:
Apparatus and associated methods of using provide convenient and economical forming of an opening through a tubular structure in a subterranean well. In a preferred embodiment, a milling guide has a guide profile formed thereon which is operative to guide a cutting tool to contact the tubular structure. An anchor portion of the milling guide grippingly engages the tubular structure to thereby axially and rotationally align the milling guide with the tubular structure.
