PCD (polycrystalline diamond) coring bits are a type of diamond drilling bit used in various industrial applications. These bits are made of a polycrystalline diamond layer that is bonded to a tungsten carbide substrate, providing high wear resistance and durability.

PCD coring bits are designed to cut through hard and abrasive materials such as concrete, masonry, and hard formations with ease. They offer a longer lifespan and faster drilling speeds compared to other types of drilling bits, making them an ideal choice for high-volume drilling operations.
