Amana Tool 46297-K SC Spektra Extreme Tool Life Coated UltraTrim Spiral 1/4 D x 1 CH x 1/4 SHK x 3 Inch Long w/Double BB Down-Cut Router Bit

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. Coating 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.
