🔍 Key Concepts

• Cutting fluids and why they’re used when threading metal • Differences between lubricants used on steel/iron vs non-ferrous metals like brass • Properties you want in a lubricant for hand threading (cooling, lubrication, chip removal)

💭 Think About

• Think about which option is traditionally recommended for machining or threading brass rather than for heavy steel work or rust protection. • Ask yourself which substance on the list is commonly known as a cutting oil used with hand tools like taps and dies. • Consider which fluids might be too thin (mostly cleaning, not lubricating) or not commonly used as a cutting lubricant for brass.

✅ Before You Answer

• Identify which choice is widely recognized as a machining/cutting lubricant, not just a general-purpose oil or coating. • Eliminate any option you know is mainly used for corrosion protection, sealing, or electrical purposes rather than for cutting. • Make sure your final choice is something you could realistically see in a machine shop or maintenance shop specifically for cutting threads by hand.
