Finish

• Aluminum chromium nitride (AlCrN) coating provides good hardness and better resistance to chemical breakdown in high-heat applications than TiAlN, TiCN, and TiN coatings.
• Aluminum titanium nitride (AlTiN) coating lubricates the end mill for high-temperature stability and abrasion resistance at high cutting speeds, offering better heat resistance than TiN, TiAlN, and TiCN coatings. Gold oxide is a low temperature heat treatment which reduces grinding stress within the tool, and is commonly used to identify cobalt steel tools.
• Titanium aluminum nitride (TiAlN) coating resists heat better than TiN and TiCN coatings, increasing tool life and performance. It also offers increased hardness compared to TiN and may reduce the need for lubricants based on the application.
• Titanium carbon nitride (TiCN) coating lubricates the end mill for high-temperature stability, and offers increased hardness and greater abrasion resistance than uncoated or TiN-coated tools.
• Titanium nitride (TiN) coating combines stability at high temperatures with hardness for wear protection, increasing tool life and performance compared to uncoated end mills.
• Uncoated (bright) tools have no finish or coating. They are a common choice for general use applications.
