ardRok <strong>Bit</strong>s<br />
HardRok is a family of bits designed<br />
specifically for hard and abrasive<br />
formations. Advancements in nose<br />
design and compact technology give<br />
these bits an aggressive yet more<br />
durable cutting structure for drilling<br />
hard West Texas carbonates. For bits<br />
drilling the hard and abrasive sands<br />
of East Texas, <strong>Hughes</strong> <strong>Christensen</strong><br />
engineers have developed a double<br />
gauge row which is aggressively<br />
positioned to reinforce the heel row<br />
and keep the bit in gauge. Other<br />
advancements such as new aggressive<br />
tooth shapes, a new stabilization<br />
system and tucked shirttails allow<br />
HardRok bits to drill longer and faster.<br />
