Analysis of High Speed Tool Steel

Cutting tools and blades are made of so-called tool steels, which are categorized into carbon tool steels (SK), alloy tool steels (SKS, SKD and SKT), and high speed tool steels (SKH). These steels are widely used for files, press punches and dies, gauges, and tool bits. Tool steel is required to have resistance to heat and wear, as well as toughness and hardenability according to the intended use. High speed tool steels in particular are suited to high speed cutting and used for high speed drills whose cutting edges need to be resistant to heat and wear.
