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 bits are your only choice. TCT dovetail bits have a stout machine made look, but are required for manmade material. All of our bits have 1/2" extended length shanks that are best with Router Boss.
