For joinery operations, you need straight and dovetail bits. Solid carbide up-cut spirals with their continuous slicing action are the best choice for straight bits. For a hand-cut dovetail look, high-speed steel dovetail (HSS) bits are your only choice. TCT dovetail bits have a stout machine-made look but are necessary for manufactured material where HSS bits quickly become dull. All of our bits have 1/2" extended length shanks that are best with Router Boss.
