- 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
- Uncoated (bright) tools have
no finish or coating. They are a common choice for general use applications.
