Amana Tool 45771-K-5, 5-Pack Solid Carbide Spektra Extreme Tool Life Coated 30 Degree Engraving 0.005 Tip Width x 1/4 SHK x 2-1/4 Inch Long Signmaking Router Bits

Spektra™ bits feature a nACo® nanocomposite coating with an extreme nanohardness and heat resistance. With a brilliant, distinctively-tinted coloring, nACo provides additional improvements in four critical aspects of router tooling.

• nACo coating is an 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.
• 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.
