Amana tool 46153-K-5, 5-Pack CNC SC Spektra Extreme tool Life Coated Phenolic, Resin and Composite Cutting with Chipbreaker Slow Helix Up-Cut 1/2 D x 1-1/4 CH x 1/2 SHK x 3-1/2 Inch Long x 3 Flute Router Bits

Designed especially to cut phenolics resin composite.Solid carbide tooling with chipbreakers that will effectively "shatter and evacuate" the chips typically produced by phenolic materials. Providing an aggressive bite, combined with a moderate helix, walking the fine line between cutting efficiency and a minimal burr finish on abrasive phenolics oftentimes impregnated with fiberglass, wood or linen.Our Spektra™ 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.Produce super-clean cuts in the following materials:Carbon FiberCarbon Fiber Reinforced PlasticCarbon Graphite Plastic PVC & Acrylic Fiberglass Hard Wood Veneered Plywood Laminate Spektra™ 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.
