ABSTRACT:
A layer of diamond formed by chemical vapor deposition (CVD) is brazed to a drill bit body to form a cutting element thereon. The ability to withstand high temperatures permits the cutting elements to be brazed using alloys requiring much higher temperatures than those used in connection with brazing convention PDC cutting elements. In an infiltrated bit, a CVD cutting element formed by chemical vapor deposition is placed in a bit mold which is thereafter filled with infiltration powder and placed in a furnace with temperature in excess of 1100.degree. Centigrade. The CVD cutting element may also be mounted on a slug or stud via brazing and the slug or stud in turn mounted on or infiltrated into the bit body or brazed thereto.
