It is used to suspend the swivel and other drilling tools. It can also be used to suspend the lifting ring and the elevator in a round trip.

The drill hook is a heavy-duty lifting device suspended from the traveling block, designed to support and connect the swivel or top drive to the drill string during rotary drilling operations. Manufactured in compliance with API Spec 8C, this hook incorporates a robust main hook body for supporting the swivel bail, along with optional elevator links for handling drill pipe and casing. The hook features a rotating mechanism that allows the supported equipment to swivel freely, preventing torque transmission to the traveling block. Safety latches on all hooks prevent accidental disengagement of bails or elevators during operations.
