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.
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.
Note: Blue based color dissipates immediately upon use. nACo® nanocomposite coating will not wear off.
WARNING! Due to the extremely small diameters involved, bits with smaller diameter of 1/8" are not guaranteed against breakage.
