The lathe tool shown as figure "T" in the illustration is commonly known as a/an __________. GS-0090

Correct Answer: Option D — right-cut roughing tool

Figure T represents a right-cut roughing tool. Its geometry is optimized for heavy material removal, feeding from right to left toward the headstock. This tool design maximizes structural strength at the cutting edge, allowing for efficient stock reduction before applying a final finishing pass on the component.
