The Liner hanger setting tools are used to run, set, and manipulate liners, and is designed to bear weight of liners after setting. The roller-bearing race and reverse-nut provide the most reliable system for releasing drill pipe from liners.
The thrust Bearing ensures positive release from liner top.
A longer polished nipple helps to judge if the sinistral-threads ware released or not.
With a trapezoidal-threaded joint, the setting tool is convenient to disassemble and carry drill pipe thread at top.
