3.  Defination
 Cutting tools are tools used to remove material
from a workpiece in the form of chips. They are used
in a wide range of manufacturing and machining
processes, such as drilling, milling, turning, and
grinding. The selection of cutting tools is crucial to the
efficiency and quality of the machining process. There
are many different types of cutting tools available,
each with their own unique characteristics and uses.

4.  Materials of Cutting Tools
 High-Speed Steel (HSS): It's a type of tool steel that contains elements
like tungsten, molybdenum, chromium, and vanadium.
 Carbide: It is also known as Tungsten Carbide. Carbide cutting tools
are made by combining tungsten carbide particles with a binder, usually
cobalt.
 Ceramic materials: such as alumina and silicon nitride are used when
high-speed machining of hardened steels, superalloys, or heat-resistant
materials is required.
 Polycrystalline Diamond (PCD): It is another synthetic material used
for cutting tools. It is made by sintering diamond particles with a binder.

5.  Cutting-tool Nomenclature
 Cutting edge: leading edge of that does cutting
 Face: surface against which chip bears as it is separated from work
 Nose: Tip of cutting tool formed by junction of cutting edge and front face
 Base: Bottom surface of tool shank
 • Flank: surface of tool adjacent to and below cutting edge
 • Shank: body of toolbit or part held in toolholder
 Nose radius: radius to which nose is ground
- Size of radius will affect finish
 Rough turning: small nose radius (.015in)
 Finish cuts: larger radius (.060 to .125 in.).
 Point: end of tool that has been ground for cutting purposes.

6.  Types of Cutting Tools
1. Based on the Number of Cutting Points
a. Single-Point Cutting Tool
b. Double-Point Cutting Tool
c. Multi-point Cutting Tool
2. Based on Material Used for Cutting Tool
a. High Carbon Steel
b. High Speed Steel
c. Ceramic Tools
d. Cemented Carbide

7.  Importance of Cutting Tools
 Cutting tools play a pivotal role across industries. They enable precise shaping
and resizing of materials like metals, wood, and plastics. Accurate cutting is crucial
for manufacturing components, creating intricate designs, and maintaining quality
standards. Well-maintained cutting tools enhance efficiency, reduce waste, and
ensure safety, making them indispensable for production, construction, and
craftsmanship.
