A drill string on a drilling rig is a column, or string, of drill pipe that transmits drilling fluid (via the mud pumps) and torque (via the kelly pressure or pinnacle drive) to the drill bit. The term is loosely utilized to the assembled series of the drill pipe, drill collars, equipment and drill bit.
