2+2 Insert Technology provides the highest quality of cut.

The CNC insert spoilboard industrial router bits with scorers features a unique 2+2 knife design that contains two cutting flutes and two up-shear scorers, which provides a smoother finish at the bottom of the cut than traditional two-knife style router bits. Engineered with an Amana-exclusive carbide grade for the highest quality of cut, maximum cutting efficiency, faster material removal process, and the longest tool life. These industrial router bits feature insert knives with four cutting edges that allow users to flip the knife over when one side becomes dull.
