Tool joints are critical short sections of pipe affixed to the tubing portion of a drill pipe using a sophisticated flash welding process. The internally threaded tool joint is known as a 'box', whereas the externally threaded tool joint is termed the 'pin'. This differentiation is crucial for their application in precision API drill pipes.
