A tool designed to crush rock efficiently while incurring a minimal amount of wear on the cutting surfaces. Invented by Howard Hughes, the rollercone bit has conical cutters or cones that have spiked teeth around them. As the drillstring is rotated, the bit cones roll along the bottom of the hole in a circle. As they roll, new teeth come in contact with the bottom of the hole, crushing the ...

The origin of twocone bit designs lies in the distant past of rotary drilling. The first rollercone patent, issued in August 1909, covered a twocone bit. As with monocone bits, twocone bits have available space for larger bearings and rotate at lower speeds than threecone bits.
Rollercone bits are generally classified as either tungsten carbide insert (TCI) bits or milledtooth bits. To assist in comparison of similar products from various manufacturers, the International Association of Drilling Contractors (IADC) has established a unified bit classification system for the naming of drill bits.
