Hybrid Drill Bits conventional PDC and roller-cone bits.
A hybrid bit can drill shale and other plastic-ally behaving formations two to four times faster than a roller cone bit by being more aggressive and efficient.
The penetration rate of a hybrid bit responds linearly to revolutions per minute (RPM) unlike that of roller-cone bits, which exhibit an exponential response with an exponent of less than unity. In other words, the hybrid bit will drill significantly faster than a comparable roller-cone bit in motor applications.
