Abstract
A drill bit includes a first tubular member including a pin end and a second tubular member including a box end. Each of the first tubular member and the second tubular member includes a respective thread structure that has, respectively, a crest extending between a top edge of a respective first flank and a top edge of a respective second flank, and a root extending between a bottom edge of the respective first flank and a bottom edge of a respective adjacent thread turn. A width of the root of the box end is less than a width of the root of the pin end such that, when the pin end and the box end are threadedly connected, the box thread structure experiences reduced maximum stress and plastic strain to prevent stripping under high torque or high tension.
