The Longyear Diamond Bit Color Series is an innovative and versatile new line of diamond coring bits. Utilizing patent-pending technology, these bits are engineered to drill faster, last longer ...

Nearly two-thirds of the oil we use comes from wells drilled using polycrystalline diamond compact (PDC) bits, originally developed nearly 30 years ago to lower the cost of geothermal drilling.

The more durable diamond bits don't have moving parts, but they can drill faster for longer in most shale rock. Now, smaller moving parts are being incorporated into the fixed bit.

Drill bit manufacturers have substantially improved polycrystalline diamond (PCD) cutters and drag bit designs since their introduction in 1972.
