Abstract
A tool joint connection includes a first tool joint and a second tool joint. The first tool joint has a male connector portion with a lobed polygonal profile extending longitudinally from one end of the first tool joint toward an opposing end thereof. The second tool joint has a female connector portion having a lobed polygonal profile extending longitudinally from one end of the second tool joint toward an opposing end thereof. The lobed polygonal profile of the male connector portion corresponds to the lobed polygonal profile of the female so the male connector portion of the first tool joint is non-rotatably receivable in the female connector portion of the second tool joint to form a connection between the first tool joint and the second tool joint.
