CA 2095662

The present invention comprises a wood bit for use in wood working applications. The blade of the bit is generally spade shaped having cutting spurs on each corner of the blade, a central point projecting from the leading end of the blade, and hooked cutting edges. A progressive transfer die is used to bend the leading end of the blade and forge a continuous hook angle extending along the side cutting spur, the lateral shoulder, and the central point of the blade. The forging of a hook extending from each side of the blade converging at a central point provides a hook along the leading end of the blade projecting outwardly (in the direction of rotation) pass the plane of the blade face, The leading end of the hook is beveled forming a continuous cutting edge extending along the hook from the outer side wall of the blade through the outside cutting spurs, along the lateral shoulders, and along each side of the central point.
