Amana Spektra bits feature a nACo nanocomposite coating with an extreme nano hardness 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.

  • Diameter: 1/4"
  • Cutting Height: 3/4"

Great coat
Size: Large, Color: Black
Sizing runs true, the quality appears to be good. I ordered the black and the color is what I expected, it’s the perfect length. The weight and thickness is perfect for temperatures in the low 30’s and up. The coat is perfect for Business wear and casual wear

Nice Coat, But Could Better
Size: Medium, Color: Black
I like this coat overall. It fits really well, nicely tapered, and a good weight, but the fabric has a sheen to it, very noticeable in brighter light, which I'm not crazy about. It doesn't have any inner breast pockets, and I don't feel secure putting my phone in the side pockets. I did get lots of positive comments from friends.

Great style chose for any occasion
Size: Medium, Color: Black
Genuinely the perfect fit and great for the style I prefer. Great material and thick to keep you warm but not to hot. Black is deep and adds that depth that I am looking for
