AlTiN+ (nACo)

  • Best for: Steels, stainless steels, titanium, and high-temp alloys

  • Choose it when: You
    need a proven, versatile coating for ferrous applications.

  • Helps with: Heat resistance, wear
    resistance, and longer life in tough cuts.

Zirc (ZrCN)

  • Best for: Aluminum
    and other non-ferrous materials

  • Choose it when: Built-up edge and finish quality are your biggest concerns.

  • Helps with: Reduced built-up edge (BUE), cleaner finishes, and smoother cutting.

Onyx DLC (ta-C)

  • Best for: Non-ferrous and highly abrasive materials

  • Choose it when: You
    need maximum lubricity and minimal material adhesion.

  • Helps with: Very low friction, high hardness, excellent adhesion resistance.

Versa (AlCrN)

  • Best for: Steels, stainless steels, tool steels, cast
    iron

  • Choose it when: Heat and wear are the primary challenges in thread milling applications.

  • Helps with: Heat resistance, wear
    protection, and stable cutting performance.

Common Coating Decisions

Frequently Asked Questions

  • No. Some tools are available uncoated, and some coatings are limited to specific families and geometries.

  • Check the product page or request a recommendation. We will confirm availability based on your tool and application.

  • Yes. If you’d like us to help you pick, include your workpiece material, coolant approach, and what you are optimizing for (tool life, finish, cycle time).

  • Most SCT coatings are applied in-house at Scientific Cutting Tools, allowing us to control scheduling, handling, and consistency throughout the coating process. Our established Platit Pi80 PVD platform continues to support many of our proven coating options, while our new CemeCon CC800 HiPIMS system expands our in-house capability with advanced coating technology and tighter process control.

  • Versa (AlCrN) is SCT’s first HiPIMS coating option, available on select thread mills. It is designed for demanding thread milling applications where heat resistance, wear resistance, and cutting stability are important.

  • No. Versa (AlCrN) is a new coating option for select thread mills. AlTiN+ remains part of SCT’s coating offering where it continues to fit the application.
