It is a lifting tool used to hang the drill string and connect the water hoses in petroleum drilling and well workover.

The drilling swivel is a critical component of the rotary drilling system, serving as the mechanical link between the traveling block and the drill string while enabling continuous rotation and high-pressure fluid circulation. Manufactured in compliance with API Spec 8C, this device incorporates a high-capacity main bearing that supports the entire weight of the drill string while allowing free rotation of the stem relative to the stationary housing. The swivel includes a gooseneck connection for the rotary hose, a washpipe and packing assembly that seals the rotating connection, and a bail for suspension from the drilling hook. Engineered for reliable performance under extreme loads, pressures, and rotational speeds, the swivel enables simultaneous rotation and circulation during drilling operations.
