ABSTRACT:
A cutter for use in fabricating dowels, plugs, or tenons has a hex-shaped shank and a body portion. The body portion includes a spur which may be carbide and is the first part of the cutter to contact the wood and which makes an initial depression into the wood. A cutting tooth has a cutting edge that may also be carbide for cutting a trough into the wood and is the widest part of the cutter. The exterior surfaces of the cutter above the cutting tooth are formed at smaller radial distances and consequently have less, if not no, contact with the piece of wood being cut. The cutting tooth may be tapered along its height whereby the bottom of the tooth would be the thickest part of the tooth and would have the most contact with the wood. Also, the portion of the cutter trailing the spur may be formed with teeth and flutes thereby reducing the amount of contact between the cutter and the wood. By reducing the amount of contact between the wood and the cutter, the cutter has a reduced amount of friction with the wood. Since a significant concern with conventional cutters is the build-up of heat, by reducing friction the cutters can also reduce the amount of heat generated and reduce any chance that the wood or the cutter becomes burned or otherwise damaged by the heat. Furthermore, the cutters are more efficient to operate since they require less torque and consume less electricity.
