Description:
Drill pipe slips have a taper of 4"/foot on diameter and other suitable dimensions to permit operation in standard master bushings. The right size drill pipe slips must always be used for the size drill pipe being handled. Slips that are smaller than the drill pipe will damage the pipe and the corners of slips as well as risk dropping a string of drill pipe entirely.
