Coating Guide: TiN vs. TiAlN vs. Nano Blue – Which Coating Fits Your Cutting Tool Needs?

At Saikeiny Tools, we understand that coating plays a critical role in tool longevity, cutting performance, and resistance to heat and wear. As a trusted manufacturer and global distributor of high-performance cutting tools, we offer a wide range of coating options for our end mills, taps, drills, and chamfer cutters—including TiN, TiAlN, and Nano Blue coatings.

In this article, we break down the key differences between these popular coatings to help you choose the best solution for your specific application.

What is TiN (Titanium Nitride)?

TiN-coated tools are widely used for general-purpose machining. This classic gold-colored coating provides:

• Excellent wear resistance
• Lower friction
• Increased tool life in standard-speed cutting

Recommended for: Mild steels, aluminum, and non-ferrous materials.

Available on: Saikeiny's HSS drills and cutting taps.

What is TiAlN (Titanium Aluminum Nitride)?

TiAlN coating offers advanced thermal stability and hardness, making it ideal for high-speed machining:

• Great oxidation resistance (up to 800°C)
• Superior performance in dry cutting
• Longer tool life in high-temperature environments

Recommended for: Stainless steel, cast iron, titanium alloys.

Available on: Saikeiny’s carbide end mills and corner radius cutters.

What is Nano Blue Coating?

Also known as Blue Nano Coating, this modern coating technology combines beauty and performance:

• Ultra-smooth surface for minimal friction
• Excellent hardness and heat resistance
• Eye-catching blue finish that reflects quality

Recommended for: High-speed finishing, aluminum alloys, carbon steels.

Available on: Saikeiny's signature series HRC55° and HRC65° carbide end mills.
