High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is superior to high-carbon steel tools in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel.
High-carbon steel (HCS) is used for softer materials such as wood, laminated particle board, and plastics due to its flexibility. [citation needed] High-speed steel (HSS) withstands higher temperatures and can cut many types of metals. [citation needed] Bi-Metal (BIM) blades contain a combination of high-carbon steel and high-speed steel. The ...
Cutting tool materials must be harder than the material which is to be cut, and the tool must be able to withstand the heat and force generated in the metal-cutting process. Also, the tool must have a specific geometry, with clearance angles designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the ...
After other high-speed steels were produced, T1 remained one of the most commonly used commercial high-speed steels for the next century. [ 23 ] [ 24 ] The next year Crucible formed the Pittsburg Crucible Steel Company, purchasing a 423-acre (171 ha) site from Midland Steel on the Ohio River near Pittsburgh for $7.5 million to build a new plant ...
Steel of about 0.8% C gets as hard as steel with more carbon, but the free iron carbide particles in 1% or 1.25% carbon steel make it hold an edge better. However, the fine edge probably rusts off faster than it wears off, if it is used to cut acidic or salty materials.
The milling process removes material by performing many separate, small cuts. This is accomplished by using a cutter with many teeth, spinning the cutter at high speed, or advancing the material through the cutter slowly; most often it is some combination of these three approaches. [2]

The mechanism used for this process is known as a planer. The size of the planer is determined by the largest workpiece that can be machined on it. The cutting tools are usually carbide tipped or made of high speed steel and resemble those used in facing and turning.
