Q

When cutting external threads on a steel pipe with a die, you should __________.

🔍 Key Concepts

• Proper use of a pipe threading die (how it’s aligned and how far it should go onto the pipe) • Use of cutting lubricant when threading steel to protect the tool and improve the cut • Safe methods for removing chips when cutting threads

💭 Think About

• Think about what happens to the die and the pipe if you strike the die with a hammer while it is cutting—does that protect or damage the tool and threads? • Consider whether steel threading is normally done dry or with some kind of oil—what is the purpose of cutting oil? • When starting threads, should the die be square (perpendicular) to the pipe or at an angle if you want clean, accurate threads? What would angled starting do to the first threads?

✅ Before You Answer

• Verify which option describes good tool care and safety rather than potentially damaging practice. • Check which option matches standard shop practice of using cutting oil or lubricant on steel threads. • Confirm that proper thread cutting requires the die to be started straight and square to the work, not cocked or angled.
