Amana Tool RC-2251 2-1/2" Insert Carbide Spoilboard Surfacing Router Bit

Features unique 2+2 insert knife design that contains two cutting flutes and two up-shear scorers, which provide a smoother finish at the bottom of the cut than traditional two-knife style router bits. A great tool for fast removal of materials over a large surface area. The scorer leaves an improved finish at the bottom of the cut. Great for surface planing. These industrial router bits feature solid carbide insert knives with four cutting edges that allow users to rotate the knife when one side becomes dull providing the highest-quality finish available on woodworking tools.
