Types of cutting tools Used in Machine Shop

Meaning of Cutting Tool:

A cutting tool in metal working can be defined as “any tool that is used to remove metal from the work piece by means of shear deformation”. Frequently, it also refers as a tool bit. In order to perform effective cutting operation, the cutting tool must be made of a material harder than the work material to be cut. Also, the tool must be able to withstand the heat generated during machining process.

The tool must have a specific geometry (known as tool geometry) for effective cutting and smooth surface finish. According to the tool geometry, the cutting tools can be classified into solid cutting tools and carbide tipped tools.

Types of Cutting Tools:

Various cutting operations require various types of cutting tools. To achieve good surface quality, proper cutting tool selection is very important.

Following are some important parameters to be considered while selecting a cutting tool for particular machining operation:

i. Geometry.

ii. Material to be machined.

iii. Shape and Size of part.

iv. Type of operation required.

v. Machine tool quality.

vi. Surface finish required.

vii. Holding facility.

viii. Machining parameters such as feed speed and depth of cut selected.

The various types of cutting tools are shown in Fig.
