Amana's Spektra Extreme Tool Life Coating is a nACo coating.
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.

This coating prevents high heat and oxidation which is detrimental to cutting tool performance.

The nACo coating offers approximately 4,500 vickers on the hardness scale.
