Amana tool 46216-K CNC SC Spektra Extreme tool Life Coated Spiral Plunge 1/2 D x 1-1/2 CH x 1/2 SHK x 3-1/2 Inch Long Down-Cut, 3-Flute Router Bit

Solid Carbide Spektra™ Extreme Tool Life Coated Spiral Plunge Down-Cut Router Bits with special unique carbide with nACo nanocomposite coating for longer lifetime.Great for production settings and excellent for creating grooves and dado cuts in softwood, hardwood, plywood and composite materials. Three-flute design for very high quality finish.The ‘Down-Cut’ cuts from the surface down leaving a smooth edge at the surface.Benefits of Mirror-Finish:Razor sharp cutting edgeEffortless chip removalHelps prevent chip re-weldingExtends tool lifeExceptional cut qualityDissipates heat well and prevents meltingSpektra™ 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.Note: Blue based color dissipates immediately upon use. nACo nanocomposite coating will not wear off.
