Why is it called High Speed Steel?
High-speed steel is highly alloyed tool steel capable of maintaining hardness even at elevated temperatures. High-speed steel is named primarily because of their ability to machine materials at high cutting speeds. The carbon and alloy contents are balanced at levels to give high achievable hardening response, high wear resistance, high resistance to the softening effect of heat, and good toughness for effective use in industrial cutting operations.

Especially suited to applications involving complicated tool shapes: drills, taps, milling cutters and broaches. High-speed steel is superior to the older high-carbon steel tools used extensively through the 1940’s in that it can withstand higher temperatures without losing its temper (hardness).
