419Carbide Coating Guide

Here’s an overview of the coatings we recommend based on our expertise and experience, along with their applications:

Coating Descriptions and Applications

AlTiN (Aluminum Titanium Nitride)

  • Applications: The top all-purpose coating for most machining tasks.
  • Advantages: Exceptional heat and wear resistance.
  • Materials: Ideal for machining steels, stainless steels, cast iron, and heat-resistant alloys.
  • Recommended Tool: 419C General Purpose End Mills and 4 Flute VX End Mills..

TiAlSiN (Titanium Aluminum Silicon Nitride)

  • Applications: Perfect for demanding high-temperature operations.
  • Advantages: Upgraded performance in tough machining conditions.
  • Materials: Excels with cast iron, aerospace materials, and pre-hardened steels.

TiN (Titanium Nitride)

  • Applications: A classic option for non-ferrous materials and light-duty machining.
  • Advantages: Good wear resistance with a signature gold finish.
  • Materials: Suited for some steels and non-ferrous materials.

TiCN (Titanium Carbonitride)

  • Applications: Designed for high-speed machining.
  • Advantages: Higher hardness and better heat resistance than TiN.
  • Materials: Excellent for hardened steels and abrasive materials.

TiAlN (Titanium Aluminum Nitride)

  • Applications: Optimized for high-speed machining.
  • Advantages: Superior heat resistance and wear resistance.
  • Materials: Perfect for steels, stainless steels, and high-temperature alloys.

TiSiN (Titanium Silicon Nitride)

  • Applications: High-temperature machining and adhesive wear resistance.
  • Advantages: Combines benefits of TiN and TiAlN.
  • Materials: Excellent for high-temp applications.

Diamond Coating

  • Applications: Extreme high-speed machining.
  • Advantages: Unmatched hardness and wear resistance.
  • Materials: Ideal for graphite, carbon fiber composites, and other abrasive materials.

Choosing the Right Coating

When selecting an endmill coating, consider these factors:

  1. Material Being Machined: Different coatings offer specific advantages based on material properties.
  2. Cutting Speed and Feed Rate: High-speed operations often require advanced coatings like TiAlSiN or Diamond.
  3. Machining Requirements: For extreme heat resistance, opt for coatings like AlTiN or TiSiN.
