High Speed Steel

Introduction to High Speed Steel (HSS)

High Speed Steel (HSS) is a versatile cutting tool material known for its toughness, heat resistance, and ability to maintain sharp cutting edges at moderate speeds. Unlike carbide, HSS tools can be used in less rigid machining environments and are well-suited for applications where cutting conditions are less stable. Their durability makes them ideal for general machining, drilling, tapping, and milling across a wide range of metals. HSS tools are widely used in aerospace, automotive, and hydraulic component industries, providing a cost-effective solution for manufacturers who need reliable performance without requiring the ultra-high speeds necessary for carbide tools.

Why would you choose High Speed Steel Tools?

HSS tools (High-speed steel tools) offer a combination of durability, flexibility, and cost-effectiveness, making them an excellent choice for many machining applications. HSS performs well in unstable cutting conditions, where vibrations or interruptions might cause carbide tools to be less effective. Additionally, HSS tools can run effectively at lower cutting speeds, making them ideal for machines that lack the high-speed capabilities needed for carbide. Their toughness and resilience allow them to withstand heavy loads and varying conditions, making them a great choice for drilling, milling, and tapping applications. For manufacturers looking for a balance of performance and affordability, HSS tools remain a good choice.

What would you use High Speed Steel as a tool for?

HSS tools are widely used for machining metals where toughness, flexibility, and lower-speed capability are essential. Unlike carbide, HSS performs well in unstable cutting conditions and is effective for interrupted cuts or machines with lower spindle speeds. 

Commonly machined materials include:

  • Aluminium
  • Titanium
  • Cast Iron
  • Alloy Steel
  • Steel Express

HSS is used in drilling applications, milling tools, and high-speed steel drill bits, making it an excellent choice for machining mild steel and high-speed steel components in aerospace industry and automotive industries.

What industries are High Speed Steel Tools used in?

Aerospace industry Icon

Aerospace Industry

HSS tools are used for machining aluminium wing panels, ribs, stringers, and flying controls, as well as titanium pylons and load-bearing structures. In military aerospace, HSS tools are also used for landing gear, older aircraft structures, and various components where machining conditions are less stable.

Automotive Industries Icon

Automotive Industries

Essential for cutting aluminium turbo housings, pump housings, cylinder heads, and gearbox housings. They are also used in cast iron engine blocks, brake callipers, and steel steering systems and drive shafts. HSS tools are also essential for machining mild steel, tool steel, and high-speed steel for manufacturing processes involving deep hole drilling and accurate drilling.
