Which lathe tool shown in the illustration would best be used on a work piece to perform a right hand facing operation? Illustration GS-0090

Correct Answer: Option C — R

Tool R is a right-hand facing tool, designed for cutting from the outer diameter toward the center of the workpiece. Its geometry allows for efficient material removal on the face of a rotating part while the lathe carriage is fed transversely, ensuring proper clearance and chip flow during the facing operation.
