This provides longevity and produces cutting results of the highest quality.Coatings prevents high heat and oxidation which is detrimental to cutting tool performance.Multi-colored hues, while attractive, will dissipate upon use and yet coating will remain fully effective.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.Spektra™ bits feature a nACo nanocomposite coating with an extreme nanohardness and heat resistance to the router bit. With a brilliant distinctively-tinted coloring nACo provides additional improvements in four critical aspects of router tooling. Blue based color dissipates immediately upon use. nACo nanocomposite coating will not wear off.Warning:  Before using any insert tool, make sure the set screw is tightened firmly.
