What is High Speed Steel primarily used for in engineering?

High Speed Steel (HSS) is primarily used for cutting tools and tool bits due to its unique properties that allow it to maintain hardness and edge retention at elevated temperatures. This characteristic is particularly beneficial when cutting materials at high speeds, as it enables efficient cutting while reducing wear on the tools.

HSS is designed to withstand the rigors of machining processes, making it ideal for drill bits, milling cutters, saw blades, and other cutting instruments. The ability of HSS to resist softening when exposed to heat generated during cutting operations is crucial for tool performance and longevity.

This focus on cutting applications is what distinguishes HSS from materials used for electrical components, construction materials, or insulation purposes, which require different mechanical and thermal properties. Hence, the application of HSS in making cutting tools and tool bits highlights its significance in engineering and manufacturing processes.
