ABSTRACT:
A well tool having a body with a plurality of sections which are joined together without welds or threads. The sections form telescoping interconnections with adjacent sections and each interconnection includes a male and female part with an outer end. The parts are telescopically joined and rotationally aligned and sealing means are positioned between each male and female part. A hole is drilled through the female part and into the male part between the ends and a removable plug is positioned in the hole for providing for the transfer of rotational and longitudinal forces. Aligned eccentrically positioned fluid passageways extend through each of the sections.
