Amana 1/4Dx1/4"SHK SPIRAL O ALU ZRN 51810-Z

CNC Mortise compression Spiral Flute Router Bits with ChipbreakerSolid Carbide SpektraA Extreme Tool Life Coated Mortise Compression Spiral with special unique carbide with nACoA‚A® nanocomposite coating for longer lifetimeThis tool contains small chip breakers that break up the chips and allow the bit to run cooler and faster.These tools have a much shorter up-cut section than the standard compression tools. they are ideal for mortising, grooving and dado.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 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.Excellent for cutting:MDF/HDFLaminateLaminated PlywoodMelamineParticle BoardSoftwood/HardwoodVeneered PlywoodCorkNote:Blue based color dissipates immediately upon use. nACoA‚A® nanocomposite coating will not wear off.Recommended RPM 20,000-21,000.
