Which material is commonly used for manufacturing cutting tools?

The most commonly used materials for manufacturing cutting tools are high-speed steel (HSS) and carbide. High-speed steel is known for its ability to withstand high temperatures without losing hardness, making it ideal for cutting tools that operate at high speeds. It can be easily shaped and holds a sharp edge, which is crucial for efficient cutting performance.

Carbide is another common material used for cutting tools, particularly for applications that require greater hardness and wear resistance. Carbide tools can maintain their cutting edge longer than steel tools, increasing their longevity and reliability in demanding machining conditions. These materials are specially designed to endure the stress and wear encountered during cutting operations, thus making them the preferred choice in the manufacturing of cutting tools.

In contrast, aluminum, plastic, and wood do not possess the necessary hardness or durability for effective cutting tool applications. While aluminum can be used for some tooling components, it is generally not suited for cutting tools due to its relatively soft nature. Plastic and wood do not have the structural integrity or sharpness retention required for cutting applications, rendering them unsuitable for this purpose.
