Solid Carbide Spektra Extreme Tool Life Coated V-Groove Router Bits Cut decorative 'V' grooves and lettering on signs with these 'V' groove bits. Use with an edge guide to chamfer and bevel edges. Can be used with handheld, table-mounted and CNC routers.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.Note: Blue based color dissipates immediately upon use. nACo nanocomposite coating will not wear off.Excellent for Cutting: Acrylic Composites Composite Decking Foam Laminate MDF/HDF Melamine Plywood PVC Plastic Sign Board Solid Surface 20lbs High Density Urethane Veneered Plywood Wood Xanita Board
