A cutting chain for cutting concrete and other similar materials having wear and stretch resistant features. In one embodiment, the cutting chain can include chain links having a debris trap for hindering the entry of debris onto bearing surfaces. In one embodiment, side links and a center link can have cooperating members forming a maze-like debris trap and can include a lubricant and/or other barrier material. In a particular arrangement, side links can have annular ribs which can be partially received in annular grooves on a center link to create the maze-like debris trap. In another embodiment, the cutting chain can include chain links having anti-rotation structures to hinder rotation of the fastener relative to the side links. In a particular arrangement, side links can have a protrusion or slot for cooperating with a complementary mating slot or protrusion on the fastener. In another particular arrangement, the side links can have ridges in the fastener receive hole for penetrating the shaft of the fastener to resist rotation thereof. |
