ABSTRACT:
A saw chain, for motor chain saws, provided with depth limiters, gauges, or members, and with cutting teeth respectively arranged, in the direction of cutting movement, behind a depth limiter. Each cutting tooth projects outwardly from a base body transverse to the direction of cutting movement of the saw chain, and is set or twisted relative to the plane of the base body, with each cutting tooth having a transverse cutter which is formed by a cutting back surface and an outer surface of the twisted cutting tooth. Each depth limiter is bent laterally out of the plane of the base body of the subsequent cutting tooth, and forms a rearwardly open, acute inclined or chamfered angle with this plane. This angle may range between 3.degree. and 20.degree., and is preferably 9.degree.. The leading region of the depth limiter may be provided with a continuously and uniformly curved, downwardly extending, rounded entry portion.
