ABSTRACT:
An anchor for a cutting tooth of a suction dredge comprises a unitary body to be welded onto the periphery of a suction head, this body having a base with a crenellated rim surrounding a tapering head designed to penetrate into a cavity of the cutting tooth. The head has a throughgoing slot alignable with similar cutouts of two lobes of the tooth receivable between crenellations of the body to accommodate a key for retaining the tooth on the head. The body consists of high-strength ductile steel, preferably alloyed with manganese and vanadium, and is formed by forging with the grains of its structure running from the base toward the tip of the head while bending around the slot thereof, the latter being produced by hot forming without chip removal.
