Tricone Bits Introduction
Tricone bit is an important tool for oil drilling. Its working performance directly affects drilling quality, drilling efficiency and drilling cost. Roller bit: It can be divided into single cone, double cone, tri cone and multi cone bits according to the number of cutter. Tricone bit is the most commonly used bit at home and abroad.Our products are mainly used in: oil drilling, water well, natural gas drilling, geothermal well drilling, air conditioning well drilling, coal mine exploration, mining, bridge construction, etc.We have a complete range of products including DTH bits, tricone bits, PDC drill bits, impregnated diamond coring bits, water well bits, oil bits, mine bits, drill pipes, drilling rigs and drilling tools. Welcome new and old customers to negotiate cooperation.
