ABSTRACT OF THE DISCLOSUREImproved bits for ingot tongs, improved tong-and-bit combinations, and an improved method of handling ingotsare disclosed. The bits are formed of a durable metal, suchas a nickel alloy or a cobalt alloy, and are rotatablyfastened in the tong arms. Protrusion from the outside facesof the tong arms are avoided to prevent damage to partsstruck by the tongs. The distance by which the points onthe bits protrude from the inside faces of the tong armscan be adjusted for different sizes of ingots. The methodincludes a step of rotating the bits through a small arc eachtime an ingot is set down, whereby a fresh area is presentedupwardly after each use and wear on the bit point is dis-tributed around the circumference.
