Tricone Bits,Rock Bits,Rock Roller Bits,Tricone Rock Bits

Tricone bits is mainly used for oil & gas,mining,water well drilling. In 1933 two Hughes engineers, one of whom was Ralph Neuhaus, invented the tricone bit, which has three cones. The Hughes patent for the tricone bit lasted until 1951, after which time other companies started making similar bits.

There are several factors that affect drill bit selection. Due to the high number of wells that have been drilled, using information from an adjacent well is most often used to make the appropriate selection.A major factor in drill bit selection is the type of formation that needs to be drilled. A soft formation includes unconsolidated sands, clays, soft limestones, red beds and shale. Medium formations include calcites, dolomites, limestones, and hard shale. Hard formations include hard shale, calcites, mudstones, cherty lime stones and hard and abrasive formations.Durability and rate of penetration are two key factors to clarify the bit quality.
