Cutting-tool technology is a crucial component of the manufacturing sector because it has a direct impact on the efficacy, precision, and affordability of machining processes. This chapter offers a succinct review of cutting-edge technology, emphasizing its importance, essential elements, and most recent developments. The introduction of the abstract highlights the significance of cutting tools in a variety of machining operations, including turning, milling, drilling, and grinding. Cutting tools are in charge of actually removing material and reshaping the workpiece to the required standards. Cutting speed, surface quality, tool life, and overall productivity are all directly impacted by how well they work. The chapter then goes over the essential features and traits of cutting instruments. It examines the components used to make tools, such as polycrystalline diamond PCD, high-speed steel, carbide, and ceramic. Each material has distinct qualities including toughness, wear resistance, and hardness that make them ideal for particular workpiece materials and applications. The chapter also emphasizes the significance of tool geometry. Rake angle, clearance angle, cutting edge shape, and tool coatings are only a few examples of the geometric features of cutting tools. Cutting pressures, chip control, heat generation, and tool life are all impacted by these aspects. For effective and precise machining, choosing the right tool shape and designing it properly is essential. The chapter also discusses current developments in the field of cutting-tool technology. It mentions the development of cutting-edge coatings that lengthen tool life, lower friction, and increase wear resistance. Examples include titanium nitride TiN, titanium carbonitride TiCN, and diamond-like carbon DLC.
