There are significant differences in the design and specifications of three cone drill bits for different rock hardness and drilling diameter usage scenarios. Common types include non sealed rolling bearing drill bits suitable for soft formations, sliding bearing sealed drill bits for medium hard formations, and special bearing drill bits for ultra hard formations.

According to the function of the drill bit, it can also be divided into comprehensive drilling drill bit, coring drill bit, and expanding drill bit. In the internationally recognized coding system, such as the IADC code, there are four letter and number combination labels that help classify and select the appropriate drill bit for specific drilling operations.

• A three cone drill bit consists of three cones, cutting structure, bearing structure, locking element, oil storage sealing device, and nozzle device. This structural design enables the drill bit to adapt to different geological conditions and improve drilling efficiency.
• The bearing types of three cone drill bits are divided into rolling bearings and sliding bearings, with different types suitable for different drilling conditions and requirements.
• The sealing types of drill bits include rubber seals and metal seals, with seal design being crucial for protecting bearings and extending drill bit life.
• The teeth can be inlaid (hard alloy teeth) or milled (steel teeth), with different tooth materials and fixing methods affecting rock breaking efficiency and service life.
• Tooth arrangement is carefully studied during design to optimize rock breaking efficiency through calculated bottom contact teeth patterns.
• The direction of the tooth crest line is engineered to improve crushing efficiency at the bottom of the well.
• Advanced modeling of bottom contact teeth distribution helps improve mechanical drilling speed and extend drill bit wear life.
