Tricone Bits, developed in the early 1930's, was a big improvement over the two cone Roller Bit. Because of its versitility and performance, it's still one of the main Rock Bits in use today.
The IADC Code describes a tricone bit, it tells you what the bit is, steel tooth or button, what formations the bit is meant for, and the bearing type. These codes help the driller describe what type of tricone they are looking for.
