Amana tool 46421-K SC Spektra Extreme tool Life Coated Spiral Plunge 1/4 Dia x 1-1/4 CH x 1/4 SHK 3 Inch Long Down-Cut Router Bit

Solid Carbide Spektra™ Extreme Tool Life Coated Spiral Plunge Down-Cut Router Bits feature unique, harder carbide with nACo nanocomposite coating for longer tool lifetime. Spiral-flute 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 ‘Down-Cut’ cuts from the surface down leaving a smooth edge at the surface. Special unique carbide grade increased clearance geometry and razor-sharp cutting edges with polished flutes provide a superior finish and longer tool life especially in abrasive materials. Great for production settings and excellent for creating grooves and dado cuts in particleboard plywood and laminate. Primarily used on CNC machines and other automatic routers. Can be used with handheld and table-mounted portable routers. Plunge shelf holes using a CNC machine: Item #'s 46211-K, 46211-L-K, 46210-K, 46212-K, 46214-K, 46216-K, 48219-K, 46220-K, 48224-K and 468228-K are specifically designed with a diameter to plunge shelf holes using a CNC machine. System 32 holes are a popular standard in cabinetry, this system refers to holes that placed at 32 mm intervals. System 32 holes are most commonly used for shelf pin holes. THE ONLY Spektra™ Coated Bits – Made in the USA  Amana Tool solid carbide router bits provide consistent, repeatable quality. Every tool is guaranteed to match the geometry on the prints, every time on every order. Best control of carbide grades for woodworking, and absolute control of quality standards on all carbide blanks. Amana Tool 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 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: Laminate Melamine Melamine Particle Board MDF Veneered Plywood Wood Note: Blue based color dissipates immediately upon use. nACo nanocomposite coating will not wear off. Note: Item #46449-K designed with extra-long cut length, specifically for cutting for guitar bodies. WARNING! Due to the extremely small diameters involved, bits with smaller diameter of 1/8" are not guaranteed against breakage.
