Description of Hughes tricone bit/steel tooth bit/steel tooth tricone bit
The original patent for the rotary rock bit was issued to Howard Hughes Sr. for his dual cone roller bit in 1909. It consisted of two interlocking wheels. Walter Benona Sharp worked very closely with Hughes in developing the rock bit. The success of this bit led to the founding of the Sharp-Hughes Tool Company.
In 1933 two Hughes engineers, one of whom was Ralph Neuhaus, invented the tricone bit, which has three wheels. The Hughes patent for the tricone bit lasted until 1951, after which time other companies started making similar bits. However, Hughes’ market share was still 40% of the world's drill bit market in 2000. The superior wear performance of pdc bits gradually eroded the dominance of roller cone bits and early in this century PDC drill bit revenues overtook those of roller cone bits.
