A cutting tooth applied to an endless chain-trenching machine to fracture and excavate the bottom. The tooth includes a mounting part for attachment to the chain and a reducing portion having a straight cutting edge at the leading end of the tooth positioned normal to the direction motion of the chain. The reducing portion is aligned from the mounting at an severe angle to the plane of the installation portion and including convex surfaces on both sides of the reducing part and a juncture collection between the mounting portion and the cutting portion forms an severe angle with the path motion of the chain whereby the cuttings made by the tooth are lifted aside by the chain as the chain is definitely digging.
