A roller-cone bit is a drill bit used for drilling through rock that features 2 or 3 abrasive, spinning cones that break up rock and sediment as they grind against it. Roller-cone bits are typically used when drilling for oil and gas. [1] A water jet flowing through the bit washes out the rock in a slurry. [2]
In 1933, Hughes Tool engineers created a tri-cone rotary drill bit, and from 1934 to 1951 Hughes's market share approached 100%. The Sharp-Hughes Rock Bit found virtually all the oil discovered during the initial years of rotary drilling, and Hughes Jr. became one of the wealthiest people in the world from its revenues.
The Hughes patent for the tricone bit lasted until 1951, after which other companies made similar bits. However, Hughes still held 40% of the world's drill bit market in 2000. The superior wear performance of polycrystalline diamond compact (PDC) bits gradually eroded the dominance of roller cone bits and early in this century PDC drill bit ...
Drill bits are broadly classified into two main types according to their primary cutting mechanism. Rolling cutter bits drill largely by fracturing or crushing the formation with "tooth"-shaped cutting elements on two or more cone-shaped elements that roll across the face of the borehole as the bit is rotated.
The company was established in December 1908 [1] as Sharp-Hughes Tool Company when Howard R. Hughes Sr. patented a roller cutter bit that dramatically improved the rotary drilling process for oil drilling rigs. He partnered with longtime business associate Walter Benona Sharp to manufacture and market the bit.
