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.

This is a Sherline high-speed steel countersink. It is perfect for cleaning holes, enlarging holes or countersinking holes. It is for use in a wide range of materials such as aluminum, metal, plastic, steel, wood, and brass. They provide a smooth finish on a variety of materials.

As it is made from high-speed steel, the single flute countersinks are ideal for:

  • chambering
  • deburring
  • countersinking

They have a 100° cutting angle. Featuring 1 flute.
