Amana Tool 46416 1/4" x 3" Solid Carbide Down-Cut Spiral Plunge Router Bit

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. Primarily used on CNC machines and other automatic routers.
