Boart Longyear

PCD Bits

Polycrystalline compact diamond (PCD) bits are ideal for drilling in soft to medium homogeneous and competent sedimentary formations.  The PCD cutters are available in several sizes and are located to yield maximum penetration rates and long life. The bits are constructed with a tough, wear-resistant matrix body and gauge reinforcement.  As a result, worn cutters can be rotated or replaced allowing the continued use of the bit.
