Abstract

Embodiments herein provide apparatuses, systems, and methods associated with a saw chain link having one or more oversized rivet holes. A rivet may be disposed in the oversized rivet hole and provide a clearance between the rivet and the edge of the oversized rivet hole that is about 0.010 inches or more. The clearance may permit the saw chain to move between two or more stable positions. The saw chain link may be a drive link, such as a cutter drive link or a bumper drive link. In some embodiments, the saw chain link may be a bi-directional saw chain link. Other embodiments may be described and claimed.
