Since 1910, HSS high-speed steel has been used as a cutting tool for more than a century. It is currently the most widely used and cheapest cutting tool material. High-speed steel drill bits can be used on electric drills or A more stable environment such as drilling machines. Another reason for the endurance of high-speed steel may be that high-speed steel tools can be re-grinded repeatedly. Because of their low price, they are not only used to grind into drill bits, but also widely used in turning tools.

HSS M35 with cobalt has better hardness and red hardness than high-speed steel, and the increase in hardness also improves its wear resistance, but at the same time, it also sacrifices part of its toughness.
