Drilling tooth, drilling tooth assembly and adapter for drilling tooth assembly

摘要

A multipiece excavating tooth assembly including an adapter, a digging or excavating tooth, and retaining pin structure for interconnecting the adapter and tooth in operable combination relative to each other. The tooth and adapter have a uniquely configured interface or conjuncture therebetween. Moreover, the conjuncture between the digging tooth and adapter is configured to advantageously orientate the retaining pin structure to avoid those problems inherent with conventional vertical and horizontal pin systems.
