High Speed Steel Cutting Tools Operate At Cutting Speed

High speed steel cutting tools operate at cutting speed.

Once heat treating was perfected it became the tool material of choice because it would run at high speed compared to carbon cutting tools. Softer metals like aluminum and mild steel have higher cutting speeds than do nasty metals like titanium or inconel. High speed steel hss or hs is a subset of tool steels commonly used as cutting tool material. So too can carbide and ceramic cutting tools achieve higher speeds regardless of the workpiece material than do ones made of high speed.

These include better and more capable machine tools and cnc processors that allow the machine to accurately cut at increasingly higher speeds and feeds. High speed steel hss was developed in the second half of the nineteenth century. What was considered high speed machining just a few years ago is regarded as conventional today. Crucible steel was awarded a patent for the first recognized high speed steel in 1910.

Many factors are driving shops to faster metal cutting rates. High speed steel is a high carbon tool steel containing a large dose of tungsten. All cutting tools have a recommended cutting speed for any given material. Hss high speed steels still playing a very significant role in metal cutting.
