Abstract
Various embodiments of the present disclosure generally provide a drive link for a saw chain including a body portion adapted to couple to adjacent side links and a tang extending from the body and sized to engage a guide bar groove. The tang may include a through hole extending from a first tang side to a second tang side and including a through hole center. In various embodiments, a material directing feature may be disposed adjacent to the through hole on at least one of the first side and second side of the tang. The material directing feature may include a recession in the tang which encourages oil and/or wood chips to pass through the through hole.
