🔍 Key Concepts

• Lathe tool shapes and their typical uses (turning, facing, threading, grooving) • How a grooving (parting) tool is drawn compared to a general turning tool • The direction of tool movement for right-hand turning vs. facing operations

💭 Think About

• Look at how tool "O" contacts the workpiece: is it cutting along the axis, across the face, or into a narrow slot? • Compare tool "O" with the other labeled tools that are clearly used for threading or general turning — does "O" look thicker, narrower, or more like a special form tool? • Ask yourself which operation requires a tool that is relatively narrow and cuts straight into the diameter of the workpiece rather than along its length.

✅ Before You Answer

• Verify whether tool "O" appears to be cutting a narrow recess or slot rather than a long surface. • Check if the cutting edge of tool "O" is square to the axis of the work instead of angled for threading or longitudinal turning. • Confirm that options involving threading or turning along the length would require a different tool shape than what is shown at "O".
