Question

Quizplus · Accepted Answer

Cemented carbides are commonly used as cutting tool material because of their high hardness, wear resistance, and toughness. They are made by combining tungsten carbide with a metallic binder such as cobalt. High-speed steel is also a common choice, but it may not be as durable as cemented carbides in some applications. Ceramics and synthetics are less common choices for cutting tool materials. High-volume steel is not a material commonly used for cutting tools.
