PDC cutters use cobalt as a binder for the diamond grit, allowing it to convert to graphite at a lower temperature than simple diamond. Two PDC cutters, identical except for the leached cutting surface in one, were subjected to a heavy wear test. In destructive testing, the cutter is destroyed and cannot be reused....
149mm PDC core bit fast penetration rates
PDC or "PAX" core bits utilise large cylindrical shaped cutters that consist of a layer of micron-sized synthetic diamond particles mounted onto a tungsten-carbide backing substrate (PDC = polycrystalline diamond compact).The technology was originally developed for oil drilling bits. PDC core bits have proved to be...

75mm 100mm 120mm 150mm PDC bit
Two different types of drill bits exist: fixed cutter and roller cone. A fixed cutter bit is one where there are no moving parts, but drilling occurs due to shearing, scraping or abrasion of the rock. Fixed cutter bits can be either polycrystalline diamond compact (PDC) or grit hotpressed inserts (GHI) or natural...
