Abstract
An excavating tooth includes a body and an abrasion-resistant layer. The abrasion-resistant layer has hardness higher than the body. The body includes a tip end face, a first face, a second face, a pair of first slope faces, and a pair of second slope faces. The abrasion-resistant layer includes a first abrasion-resistant layer section and a second abrasion-resistant layer section. The first abrasion-resistant layer section is formed on the tip end face. The second abrasion-resistant layer section is formed respectively on the pair of first slope faces and the pair of second slope faces. Thereby, it is possible to obtain an excavating tooth and a body for the excavating tooth capable of keeping a penetration force of a blade edge high in penetrating into an excavation subject.
