Diagram for question 142
AI Explanation
The correct answer is D) knurling tool. A knurling tool is a lathe tool that is used to create a textured pattern or "knurling" on the surface of a workpiece. This is commonly done to provide a better grip on cylindrical parts, such as handles or knobs. The illustration GS-0090 clearly shows a knurling tool, which is the correct identification based on the function and appearance of the tool depicted. The other answer choices are incorrect as they do not accurately describe the type of tool shown in the illustration. A curling, hurling, or furling tool would not be the appropriate identification for the lathe tool depicted.
