Solid Carbide Spiral Upcut Double Flute
The solid carbide spiral upcut bits are made from a solid carbide rod with precision ground double flutes. These plunging upcut bits provide a superior cut due to their shearing action and pull the chips toward the router base making them ideal for mortises and other uses where you have trapped chips or finish quality is important.
All of our router bits are Made in USA by the award winning Whiteside Machine in their North Carolina factory.
