High-Speed Steel Square End MillsSquare End Mills
High-speed steel square end mills offer good wear resistance for basic milling applications. They re more flexible and can absorb more shock and vibration than carbide powdered-metal or cobalt end mills. Sometimes called square-nose end mills square end mills have a square nose and are rotated against a piece of stock to create a flat

The cutting speeds for high speed steel listed below are recommended for efficient metal removal rates. These speeds may be varied slightly to shift factors such as the condition of the machine the type of work material and sand or hard spots in the metal. The RPM at which the lathe should be set for cutting metals is as follows

High-speed steelWikipedia
High-speed steel (HSS or HS) is a subset of tool steels commonly used as cutting tool material.. It is often used in power-saw blades and drill bits is superior to the older high-carbon steel tools used extensively through the 1940s 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

Tool Considerations for High Speed Cutting Modern
Metal removal rates are faster today than ever before. What was considered high speed machining just a few years ago is regarded as conventional today. Many factors are driving shops to faster metal cutting rates. These include better and more capable machine tools and CNC processors that allow the machine to accurately cut at increasingly higher speeds and feeds.
