It is a tool put into the rotary table bushing to lock and hang the drill string in well drilling.

Drill collar slips are specialized rotary tools designed to suspend and secure drill collars in the rotary table during tripping, making up, or breaking out operations. Manufactured in compliance with API Spec 7K, these slips feature a segmented, hinged construction with extended length to distribute the heavy load of drill collars over a larger contact area, preventing damage to the collar surface. The slips are equipped with interchangeable, non-marking gripping inserts that provide secure holding without gouging or stress concentration on the drill collar. The handle design facilitates easy installation and removal while maintaining positive engagement during operation.
