The tool used for cutting external pipe threads is called a pipe _______________.

AI Explanation
The correct answer is D) stock and die. A stock and die is the tool used for cutting external pipe threads. It consists of a metal stock that holds the die, which is the threaded cutting tool. The die is rotated around the pipe to cut the threads. This is the standard tool and process for creating external pipe threads as specified in industry standards and regulations. The other options are incorrect because: A) a pipe cutter is used to cut pipes, not create threads; B) a ratchet cutter is a specialized pipe cutter, not a threading tool; and C) a threader is a tool for cutting internal pipe threads, not external threads.
