Abstract
A saw chain for cutting hard abradable material is shown and described. The saw chain cuts with an abrasive particle impregnated mesh structure. In one embodiment, the saw chain has right and left support links carrying the diamond mesh upon inclined support surfaces inclined relative to the travel axis of the saw chain. The abrasive particle impregnated mesh contacts the material to be cut only adjacent its trailing edge. A consumable material exists between the impregnated mesh and the support surface. The impregnated mesh may extend downward along the side of the support link to maintain a constant kerf width. In another embodiment, a formed cover is mounted on joined side link pairs of the saw chain. The cover has an abrasive particle impregnated mesh on an inclined surface and on select areas of its side skirts. The skirts cover as least a portion of the bores in the drive links and support links to retain and protect the fasteners therein.
