Abstract:
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.
