Polycrystalline diamond compact (PDC) drill bits are key drilling tools for oil exploration and drilling, with an annual market value of more than $4.5 billion for PDC cutters.
The term "diamond bit" normally refers to bits incorporating surface-set natural diamonds as cutters. This bit type, which has been used for many years, was the predecessor to PDC bits and continues to be used in certain drilling environments. Diamond bits are used in abrasive formations. They drill by a high-speed plowing action …
