🔍 Key Concepts

• Match each tool shape (A–G) with the finished workpieces in Figs. I–VI to see what each tool is used for. • Identify what kind of cut is shown in Fig. VII (grooving, threading, facing, or turning). • Think about which tool would give a flat-bottom groove with square sides versus an angled or pointed profile.

💭 Think About

• Look closely at the cross‑section of the groove in Fig. VII. Are the sides straight and parallel, angled, or V‑shaped? • Which tool tip has a shape that would reproduce that same cross‑section if plunged straight into the rotating stock? • Among A, B, D, E, which tools are clearly meant for threading or general turning, and which one is specifically for cutting a groove or shoulder?

✅ Before You Answer

• Verify the tip profile of each candidate tool against the shape of the groove in Fig. VII. • Eliminate any tool that would leave a V‑shaped or angled-bottom cut, since Fig. VII does not show that. • Confirm that the chosen tool could be used in a straight plunge cut to form the full width of the groove in a single pass.
