Amana tool 43742-K SC Spiral Plunge with Corner Radius 0.060 R x 5/16 Dia x 7/8 CH x 3/8 SHK x 2-1/2 Inch Long Up-Cut Spektra Extreme tool Life Coated Router Bit

Solid Carbide Spiral Flute Plunge with Corner Radius Router Bits   Spiral bits combine a shearing action in cutting with an augering action in chip clearance. The shearing action yields an especially clean & accurate cut, while the augering action clears chips from the cut. The “up-cut” shears from the bottom up, pulling chips from the bottom up, thus allowing deeper penetration with less stress on the tool. An excellent choice for mortising.Unique carbide grade for longer lifetime Produces a superior finish and longer tool lifeRazor-sharp cutting edges/polished flutes'Can be used with hand-held, table-mounted portable routers and CNC machinesIndustrial quality Excellent for cutting:MDFSoft/Hard PlasticSoft/Hard WoodSpektra™ 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 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.
