🔍 Key Concepts

• Lathe tool geometry – notice the shape of the cutting edge and which direction it would feed along the workpiece • Difference between a roughing/turning tool and a cutting‑off (parting) tool • How a facing tool is ground to cut toward the center of the work

💭 Think About

• Look at figure B and imagine it mounted in the toolpost: in which direction would the sharp edge remove metal if the work rotates toward you? • Which of the choices describes a tool used mainly to cut a groove all the way through (to separate a piece), and does figure B look narrow like that or more like a broad turning edge? • If this were a facing tool, would its cutting edge be arranged mostly across the face of the work or along the side? Compare what you see.

✅ Before You Answer

• Verify whether the tool in figure B has a narrow blade centered on its width (typical of cutting‑off tools) or a broader side-cutting edge (typical of roughing/turning tools). • Check the angle of the cutting edge to decide if it is meant to cut when feeding left‑to‑right or right‑to‑left along the workpiece. • Confirm whether the nose is rounded or pointed, which helps distinguish a round‑nose turning tool from the others.
