Those seeking improved surface finishes in either plastics or hardwoods do well to move up to Amana Tool’s 3 flute Low Helix Finishers. The unbeatable combination of three keen edges and a gentle 10 helix, equates to a stiffer tool that minimizes both part movement and edge burring, leaving a smooth finish.

Our 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 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.

Note: Blue based color dissipates immediately upon use. nACo nanocomposite coating will not wear off.
