External threads on pipes are cut with which tool?

External threads on pipes are cut with which tool?

• A. Tap
• B. Reamer
• C. Die
• D. Chisel

Answer: (C)

The main idea is how to create threads on the outside of a pipe. A die is the tool used for external threading, cutting the ridges around the outside surface as you rotate it around the rod or pipe. Taps, by contrast, are designed to cut threads inside holes. Reamers are used to enlarge or finish holes, not to cut threads, and chisels aren’t used for threading at all. In pipe work, the die (often used with a die stock) shapes the external threads so fittings can screw on securely.
