Cutter Material

• Carbide resists abrasion and high cutting temperatures. It can run at higher speeds and is harder than high-speed steel.
  
• Cobalt steel is used for tough machining applications and on materials such as cast iron, cast steel and heat-treated steel. Cobalt steel resists abrasion and high cutting temperatures and has higher feed rates compared to high-speed steel.
• High-speed steel is a common general purpose steel for cutting tools, is compatible with a variety of materials, and tends to be lower in price.
