What's the difference between PDC and PCD Drill bit?

- Aug 03, 2017-

PDC means Polycrystalline Diamond Composite or Compact.

PDC are made by combining some layers of polycrystalline diamonds (PCD) with a layer of cemented carbide liner at high temperature and high pressure.

PDCs are among the most rigid of all diamond tool materials.

PCD simply means Polycrystalline Diamond : PCD are normally made by sintering many micro-size single diamond crystals at high temperature and high pressure. PCD has good fracture toughness and good thermal stability, and is used in making geological drill bits.
PDC has the advantages of diamond’s high wear resistance with carbide’s good toughness.
