Q

It is necessary to 'chalk' a file when the metal you are filing is __________.

🔍 Key Concepts

• Loading of file teeth when working on different metals • How soft, gummy, or non-ferrous metals behave when filed • Why chalking a file helps prevent clogging and scoring of the work

💭 Think About

• Think about which of the listed metals is most likely to clog or pack into the teeth of a file instead of producing clean chips. • Which metal on the list is softer and more prone to smearing rather than cutting cleanly when worked with hand tools? • When would you want chalk as a barrier between the file and the work so the file does not "pin" or load up?

✅ Before You Answer

• Identify which option is a soft, non‑ferrous metal among the choices. • Ask yourself: For which metal does the file most easily clog or load up, requiring chalk to keep the teeth clear? • Eliminate any metals that are harder structural steels where loading is less of a problem.
