High Speed Steels (HSS)

What Are High-Speed Steels (HSS)?

High-speed steels (HSS) are special alloy steels that maintain their hardness and durability even at high cutting speeds, and they exhibit exceptional wear resistance. These steels perform well at elevated temperatures and are particularly suitable for cutting tools and machining operations.

Where Are High-Speed Steels Used?
High-speed steels are used in various industrial and manufacturing applications. Main applications include:

  • Cutting Tools: Drill bits, mills, lathes, and other cutting tools.
  • Drilling and Cutting: High-speed drilling, cutting, and chip removal processes.
  • Turning and Milling Operations: Cutting tools that operate at high speeds in machining processes.
  • High-Performance Operations: Cutting tools that work under high temperatures and severe conditions.
