🔍 Key Concepts

• How the cutting edge of tool Q is shaped and oriented compared to tools P, R, and S • Difference between roughing tools and finishing/smooth-surface tools on a lathe • How a tool’s nose radius and angle affect the finish on the workpiece

💭 Think About

• Compare tool Q’s shape to the other tools: which ones look designed to remove a lot of metal quickly, and which look designed to leave a smoother surface? • Look at the direction tool Q would feed along the work: is it mainly working on the side, the end, or along the diameter? • Ask yourself whether Q seems intended for a special operation (like cutting off) or for general longitudinal turning along the shaft

✅ Before You Answer

• Verify whether tool Q’s cutting edge is narrow and straight (typical of cutoff tools) or broad with a radius (typical of finishing tools). • Check if the tool is clearly arranged for left-hand or right-hand feed; eliminate any choice that doesn’t match that feed direction. • Decide if Q looks more like the tools labeled for rough turning or more like one intended to leave a smooth, finished surface.
