A Polycrystalline Diamond Compact (PDC) bit is a special type of diamond drilling bit that does not use roller cones but instead has polycrystalline diamond inserts.
A PDC cutter has high hardness, wear-resistance, and great tenacity, widely used for making drill bits/tools for oil, gas, and mining.
PDC bits are an alternative to Tungsten Carbide (TC) bits and surface set diamond bits when drilling in non-consolidated and medium hard rock formations such as salt, potash, limestone, and claystone with no crystalline or chert or similar intrusions.
PDC Coring Bits with/without face discharge: Good cutting, fast penetration, long bit life in Soft / Medium hard-rock formations.
In applications where drill bit life is dominated by abrasive wear, PCD bits perform in an order of magnitude compared to the lifetime achieved by tungsten carbide bits.
