Abstract: A rock cutting tooth assembly for a dredge cutterhead in which each tooth has a cutting edge formed by the intersection of a cutting face substantially lengthwise with the tooth and a flank substantially transverse to the tooth, the cutting face lying in a plane which intersects the axis of the base of the tooth at a location inwardly of said base, and said plane being angularly disposed with respect to a profile plane from the center of the cutterhead to the cutting edge. Preferably, there is disposed another such tooth with its cutting face oppositely facing the first tooth cutting face and the axis of the base of the tooth is angularly disposed with respect to the axis of the adapter landing.
