High-Speed Steel

A high- speed steel tool is a tool with a special ability. This ability allows for machining at high cutting speeds. It also yields an unusually high resistance to heat. It can resist softening at temperatures of up to 600 degrees Celcius, 1112 Fahrenheit.

This high heat resistance means high wear as well as toughness. Additionally, it can retain its hardness for longer. It has a low weldability factor as well as lowered ductility.

Center drills are made of high speed steel. They are useful for creating holes for a lathe center. They have a 2 part tip. It has a small pilot as well as the larger countersinking area of the bit.
