A single point cutting tool is one of the most important tools used in machining work. It is widely used in lathes, shaping machines, and planning machines. As the name suggests, this tool has only one cutting edge that removes material from the workpiece.
This tool is very popular in workshops, industries, and technical training centers because it is simple to use, low cost, and effective. Beginners also find it easy to understand and operate. In this article, you will learn everything about single point cutting tools in easy English.
2. What Is a Single Point Cutting Tool?
A single point cutting tool is a tool that has one sharp edge to cut metal or other materials. It removes unwanted material in the form of chips to give the workpiece the desired shape and size.
Unlike multi-point tools like drills or milling cutters, this tool works with a single cutting edge. It is mainly used for turning, facing, threading, and grooving operations.
3. Main Parts of a Single Point Cutting Tool
A single point cutting tool has several important parts. Each part has a specific function.
3.1 Shank
The shank is the main body of the tool. It holds the tool firmly in the tool holder.
3.2 Face
The face is the top surface where chips slide after cutting.
3.3 Flank
The flank is the side surface that faces the workpiece.
3.4 Cutting Edge
This is the sharp edge that actually cuts the material.
3.5 Nose
The nose is the small rounded tip where the side and end cutting edges meet.
4. Types of Single Point Cutting Tools
Single point cutting tools are available in different types based on their use.
4.1 Turning Tool
Used to reduce the diameter of a rotating workpiece.
4.2 Facing Tool
Used to create a flat surface at the end of the workpiece.
4.3 Parting Tool
Used to cut off a part from the main workpiece.
4.4 Thread Cutting Tool
Used to cut threads on bolts, screws, and rods.
4.5 Grooving Tool
Used to make narrow grooves on the workpiece.
5. Materials Used for Single Point Cutting Tools
Different materials are used to make cutting tools, depending on the job.
5.1 High Speed Steel (HSS)
HSS tools are strong, durable, and easy to sharpen. They are commonly used in small workshops.
5.2 Carbide
Carbide tools are very hard and last longer. They are used for high-speed cutting.
5.3 Ceramic
Ceramic tools are used for high-temperature and high-speed operations.
5.4 Diamond
Diamond tools are extremely hard and used for very fine finishing work.
6. Working Principle of Single Point Cutting Tool
The working principle is simple. The workpiece rotates or moves, and the cutting tool remains fixed. As the tool touches the workpiece, its sharp edge removes material layer by layer.
The removed material comes out as chips. The size and shape of chips depend on cutting speed, feed rate, and depth of cut.
7. Advantages of Single Point Cutting Tool
Single point cutting tools have many benefits.
- Easy to design and use
- Low cost compared to complex tools
- Simple sharpening process
- Suitable for many operations
- Good control over cutting process
Because of these advantages, they are widely used in basic machining tasks.
8. Disadvantages of Single Point Cutting Tool
Like every tool, it also has some limitations.
- Cutting speed is slower
- Not suitable for mass production
- Tool wear can be high
- Less efficient than multi-point tools
Despite these disadvantages, it is still very useful for small and medium jobs.
9. Uses of Single Point Cutting Tool
Single point cutting tools are used in many industries.
- Machine workshops
- Automobile industry
- Tool rooms
- Training institutes
- Repair and maintenance work
They are mainly used on lathe machines for turning and shaping work.
10. Safety Tips While Using Single Point Cutting Tool
Safety is very important during machining.
- Always wear safety glasses
- Use proper tool holding
- Do not touch chips with bare hands
- Keep correct cutting speed
- Stop the machine before adjusting the tool
Following these tips helps avoid accidents.
