Our Coatings
Engineered Coatings That Maximise Tool Performance
ATA offers a range of high-performance coatings—Accelerator-P, Accelerator-N, and Accelerator-K—each purpose-built to deliver peak performance in specific material applications. These advanced coatings boost tool life and efficiency by enhancing properties such as heat resistance, lubricity, adhesion resistance, and wear resistance.
Every coated tool in our lineup is fully stocked and available for same-day shipping—so you get top-tier performance without the wait.
