PDC Drill Bit Design and Field Application Evolution
An early field test of a petroleum drill bit that used PDC cutters took place in Nov. 1973 in Colorado. From these tests, numerous inherent design weaknesses were apparent. The problems are thoroughly documented by Walker et al. Basically, the problems were that the small-diameter (0.323-in. [8.2-mm) blanks did not provide sufficient area to ...Web

Tungsten carbide | hardness, strength, durability | Britannica
Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600° C (4,700° F). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400°–1,600° C (2,550°–2,900° F). For fabrication, a process developed in the 1920s is employed: the …Web
