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.
CPM REX T15(HSS) [55] is super high-speed steel made by the CPM process. It is a tungsten type high speed containing high vanadium for excellent abrasion resistance, and cobalt for good red hardness, and is used for cutting difficult-to-machine materials where high frictional heating is encountered.

Cold saw blades are used to cut metal using a relatively slow rotational speed, usually less than 5000 surface feet per minute (SFM) (25 m/s), and a high chip load per tooth, usually between .001"–.003" (0.025–0.08 mm) per tooth. These blades are driven by a high power motor and high-torque gear reduction unit or an AC vector drive.
For several decades now, hacksaw blades have used high speed steel for their teeth, giving greatly improved cutting and tooth life. These blades were first available in the 'All-hard' form which cut accurately but were extremely brittle. This limited their practical use to benchwork on a workpiece that was firmly clamped in a vice. A softer ...
Rotary cutting tools include drill bits, countersinks and counterbores, taps and dies, reamers, and cold saw blades. Other cutting tools, such as bandsaw blades, hacksaw blades, and fly cutters, combine aspects of linear and rotary motion. The majority of these types of cutting tools are often made from HSS (High-Speed-Steel).
High-speed steel (HSS) The whole saw blade is made of High-Speed Steel (HSS). HSS saw blades are mainly used to cut steel, copper, aluminum and other metal materials. If high-strength steels (e.g., stainless steel) are to be cut, the blades made of cobalt HSS (e.g. M35, M42) should be used. Tungsten carbide
