nACo offers approximately 4,500 Vickers for impressive solid hardness on cutting areas of the tool, for an increase up to 2.5 times compared to uncoated bits.
The coating on cutting tools protects against damage from high temperatures and oxidation. Although the multi-colored hues may fade with use, the coating will continue to be effective.
nACo coating is a micro-thin ceramic coating which enables the tool's cutting edge to retain crucial sharpness and lubricity. This provides longevity and produces cutting results of the highest quality.
