Which type of machining tool has one cutting edge and is primarily used on lathes?

• A. Single-Point Cutting Tools
• B. Multi-Point Cutting Tools
• C. Drills
• D. Milling Tools

Answer: (A)

The type of machining tool that has one cutting edge and is primarily used on lathes is the single-point cutting tool. This tool is specifically designed for tasks such as turning, which involve removing material from a rotating workpiece. The single-point design allows for precise control over the cutting process, making it ideal for creating specific shapes and surfaces on cylindrical workpieces. Single-point cutting tools can be used for various operations, including shaping, facing, and threading. The simplicity of having just one cutting edge enables the tool to focus on a specific area of the workpiece, allowing for greater accuracy in cutting depth and surface finish. This characteristic makes single-point cutting tools integral to lathe operations, as they can be adjusted easily for different machining requirements. In contrast, multi-point cutting tools have multiple cutting edges and are used for operations like milling, where a broader surface needs to be machined simultaneously. Drills are specifically designed for creating holes and have a different structure and application. Milling tools, used in milling machines, typically feature multiple cutting edges also designed for producing flat surfaces or complex shapes on a workpiece. Thus, the unique design and application of the single-point cutting tool is what establishes it as the correct answer in this context.
