    摘要: A method of re-processing used TSP material layers to form cutting elements, bits with such cutting elements mounted on their bodies, and bits having re-processed TSP material layers attached to their bodies, as well as such cutting elements and bits are provided. The method includes providing a used TSP material cutting element having a TSP material layer and substrate, or a bit having a TSP material layer attached to the bit, removing the used TSP material layer from the cutting element or bit, cutting the used TSP material layer to a new shape, if necessary, optionally re-leaching the used TSP layer and re-using the TSP material layer to form a cutting element, or in forming a bit body. The formed cutting element may be mounted on a bit body.

    摘要: A cutting element for a drill bit that includes an outer support element having at least a bottom portion and a side portion; and an inner rotatable cutting element. A portion of the inner rotatable cutting element is disposed in the outer support element, where the inner rotatable cutting element includes a substrate and a diamond cutting face having a thickness of at least 0.050 inches disposed on an upper surface of the substrate; and where a distance from an upper surface of the diamond cutting face to a bearing surface between the inner rotatable cutting element and the outer support element ranges from 0 to about 0.300 inches.
