- Aluminum titanium nitride (AlTiN) coating has high surface hardness at elevated temperatures, suitable for machining titanium, nickel-based alloys, cast iron, tool steels, and stainless steel.
- Chromium nitride (CrN) is a low-friction
coating, with high surface hardness that helps improve edge sharpness
and helps prevent buildup of material on the tool’s cutting edge. It is
suitable for machining aluminum, copper, and steel.
- Titanium aluminum nitride (TiAlN) resists
heat better than TiN, which helps increase tool life and performance. It
also has increased hardness compared to TiN and, at high cutting
speeds, may reduce the need for lubricants, based on the application. It
is suitable for machining titanium, nickel-based alloys, cast iron, and
- Titanium diboride (TiB2) is a compound composed of titanium and boron, which is harder than steel, has a high melting point, and has high electrical and thermal conductivity.
- Titanium nitride (TiN) 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 additional surface treatment or coating. They are a common choice for general use applications.
