<p>The invention is directed to a saw chain for a motor-driven saw such as a handheld, portable motor-driven chain saw. The motor-driven saw has a guide bar defining a track for accommodating and guiding the saw chain in a predetermined direction of movement. The saw chain includes a plurality of cutting links, a plurality of connecting links and a plurality of driving links, the links being pivotally interconnected by rivets or the like to define the saw chain. Each of the cutting links includes a plate-like body having a base web for defining rearward and forward openings for receiving respective ones of two of the rivets therein. The plate-like body has a rearward portion extending upwardly from the rearward region of the base web to define a cutting tooth. The plate-like body has a forward portion extending upwardly from the forward region of the base web so as to be spaced from the cutting tooth. The forward portion is bent over transversely to the direction of movement at a predetermined distance from the base web to define a depth limiter. The depth limiter has an upwardly directed top surface subdivided into a bearing face directly adjacent to the cutting tooth and an abutment face extending forwardly of the bearing face so as to be inclined downwardly in the direction of movement.</p> |
