n: the tendency of a body, such as a length of drill pipe, to be bent by the action of a tool, such as the slips, applied to it with a great deal of force. In the case of drill pipe, if the slips are allowed to stop the drill stem as the driller lowers it into the hole, the slips can swage, or deform, the body of the pipe by the force they apply against the pipe when they settle into the master bushing.
