Here, in this article we will discuss about each and every aspect like definition, nomenclature, pros and cons etc. of single point cutting tool. So, stay tuned till end, you will definitely learn a lot today.

What is single point cutting tool?

Single point cutting tool is the most prominent tool in machining industry that helps to perform several operations like facing, turning, planning etc. on lathe, shaper or planer machine.

Materials used for single point cutting tool

There are many materials which can be used for the single point cutting tool. Some important are discussed below-

  • High speed steel (HSS)
  • High carbon steel
  • Ceramics
  • Cermets
  • Polycrystalline Diamond
  • Cemented carbide
  • CBN (Cubic boron nitrite)
  • Cast alloys (such as stellite)

What are the different angles used in single point cutting tool?

Single point cutting tools are comprised of various different different angles. It becomes easier to understand the working of single point cutting tool.

The angles are given below:

  1. Back Rack angle
  2. Side rack angle
  3. Side cutting edge angle
  4. End cutting edge angle
  5. Side relief angle
  6. End relief angle

Nomenclature of single point cutting tool

There are many different terms used in single point cutting tool. These terms describes the entire construction of the single point cutting tool.

The different terms are given below-

  1. Shank

Shank is the main part of the tool. This is used to hold the tool that’s why it is also known as tool holder.
It is the back portion of the tool which is supported by tool post.

  1. Face

Face is the top surface of the tool. It is the horizontal surface adjacent of the cutting edges.
After the cutting, the chips passes on it.

  1. Flank

It is the vertical surface adjacent to the cutting edge. Flank is also known as the cutting face.
We can divide it as side flank and end flank.

  1. Heel

It is basically the intersection of flank and the base of the tool. You can recognise this as the curved portion at the bottom of the tool.

  1. Nose

It is the point where the side cutting edge and end cutting edge meets. It is situated at the front end of the tool.

  1. Base

Base is the bottom surface of the single point cutting tool. It is observed as the opposite surface of the face.

  1. Nose radius

The curved radius of the nose at it’s sharp point is termed as nose radius. Nose radius provides long tool life and better surface finish.

What are the pros and cons of single point cutting tool?

Everything in this entire universe has the pros and cons. Similarly, single point cutting tool also have some pros and cons.


  • This is simplest type of machining tool.
  • The price is comparatively cheaper.
  • Design and manufacturing is easier.


  • Single point cutting tool is comparatively less productive.
  • The metal removal rate is also low.
  • Here the tool wear is quite high.
  • Tool life of single point cutting tool is comparatively shorter.
