Finish

  • Aluminum chromium nitride combines good hardness in high heat with high oxidation resistance and reduces the coefficient of friction. This coating has excellent wear resistance, and is good for use on ductile cast iron and carbon steel.
  • Black oxide is a blue gray-colored coating that combines good hardness in high heat with high oxidation resistance. This coating has excellent wear resistance. Good for use on ductile cast iron and mild and high carbon steels.
  • Black and gold oxide is an appealing surface treatment which combines the benefits of both black oxide and gold oxide.
  • Gold oxide is a low temperature heat treatment which reduces grinding stress within the tool, and has an appealing, easy-to-identify gold color. Gold oxide is commonly used to identify cobalt steel tools.
  • Titanium aluminum nitride (TiAlN) is a rose-colored ceramic coating that is tough and has high oxidation stability, and extends the life of the tool. It becomes self-lubricating at higher speeds, making it ideal for cutting without coolant ("dry machining"). Good for machining titanium, nickel-based alloys, cast iron, and stainless steel.
  • Titanium carbonitride (TiCN) is a blue gray-colored ceramic coating that is harder than TiN and has lower friction. It combines toughness with good wear resistance. Good for use on items made of ductile cast iron, stainless steel, aluminum, carbon steel, and plastic.
  • Titanium nitride (TiN) is a gold-colored ceramic coating that combines hardness and low friction to extend cutting tool life and permits faster cutting speeds than with uncoated tools. Good for use on items made of alloy steel, carbon steel, plastic, and aluminum.
  • Uncoated (bright) tools have no finish or coating. They are a common choice for general use applications.
  • Uncoated (bright) with TiN tip have titanium nitride only at the tip of the cutting tool. TiN is a gold colored ceramic coating that is hard and has low friction, permitting faster cutting speeds than uncoated tools.
