Cutting tools may be classified according to the number of major cutting edges (points) involved as follows:
• Single point: e.g., turning tools, shaping, planning, and slotting tools (parting tool), and boring tools
• Double (two) point: e.g., drills
• Multipoint (more than two): e.g., milling cutters, broaching tools, hobs, gear shaping cutters, etc.

Which one of the following is a single-point cutting tool?a)hacksaws ...
Single-point cutting tools are tools that have a single cutting edge or point that is used to remove material from a workpiece. These tools are commonly used in machining operations to shape and finish parts. Among the given options, the correct answer is option 'D' - parting tool.
A parting tool is a type of single-point cutting tool that is used to create deep grooves or cut off sections of material from a workpiece. It is typically used in metalworking applications, such as turning or lathe operations, where the tool is held rigidly and forced into the material to create the desired cut or groove.
Here are some key points about the parting tool:
1. Purpose: The primary purpose of a parting tool is to create deep grooves or cut off sections of material from a workpiece. It is often used to separate a finished part from the remaining stock or to create deep channels or slots.
2. Design: A parting tool typically has a straight, narrow blade with a single cutting edge. The blade is held in a tool holder or tool post and is positioned perpendicular to the workpiece. This design allows for precise and controlled cutting.
3. Cutting Process: When using a parting tool, the blade is forced into the workpiece to create the desired cut. The cutting edge removes material by shearing or scraping, resulting in a clean and accurate cut.
4. Material Compatibility: Parting tools are commonly used on materials such as metal, plastic, and wood. The specific tool and cutting parameters may vary depending on the material being cut.
5. Safety Considerations: When using a parting tool, it is important to follow proper safety precautions. This includes wearing appropriate personal protective equipment, such as safety glasses or goggles, and ensuring the workpiece is securely held in place to prevent movement during the cutting process.
In conclusion, a parting tool is a type of single-point cutting tool that is used to create deep grooves or cut off sections of material from a workpiece. It is commonly used in metalworking applications and is an essential tool for machining operations.
