Amana PLUNGE 3/8 DIA UPPER BB 1/4SHK 45475-3DS

Solid Carbide SpektraA Extreme Tool Life Coated Signmaking and Engraving Router Bits with special unique carbide with nACoA‚A® nanocomposite coating for longer lifetime.For extra-fine carving and lettering details for signmaking.These tools are used for wood, plastic and solid surface materials.SpektraA bits feature a nACoA‚A® 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 theA‚A 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. nACoA‚A® nanocomposite coating will not wear off.WARNING!: Maximum RPM=28,000
