Benefits of Aluminum Titanium Nitride Coating

With the right coating applied, your cutting tools can last longer, perform better, and save you time and money. Coatings are a common and cost-effective addition to a reamer, end mill, thread mill, or drill. Using a vacuum process called physical vapor deposition, or PVD, different combinations of materials are applied to cutting tools to coat them for specific performance benefits.

One of the more common tool coatings is AlTiN, a combination of aluminum (Al), titanium (Ti), and nitride (N). AlTiN is a good coating option if you are working with hardened steel, high-temperature alloys, low carbon steel, carbon steel, martensitic stainless steel, PH stainless steel, and titanium.

The Right Coating

AlTiN coating provides a variety of benefits, including:

• Abrasive wear resistance
• Added lubricity that can aid in chip removal
• Oxidation resistance
• Heat reduction in high-speed and high-temperature operations

The Right Process

While choosing the right coating is important, it’s also critical to choose a cutting tool manufacturer with the knowledge and experience to apply any coating properly. MITGI offers several in-house coating options using processes that create the proper coating thickness for each tool, each time. When we apply coating to cutting tools, we batch tools of the same cutting diameter to apply the optimal amount of coating for the tool size. By coating our tools in-house, we also make sure that, for example, the coated reamer we supply six months from now for your work will have the exact same coating thickness as the reamer you’re currently using. We know that coating thickness can impact the tool size, and we consider that when making our cutting tools.

Since AlTiN is a popular coating, we can accommodate AlTiN tool coatings with a lead time of just a day or two. If you want to consult with experts on tool coatings, reach out to MITGI, and we will be happy to help you select the right coating for your application.
