9 7/8inch (250mm) IADC137 Fast Drilling Rate Mill Tooth Tricone Drill Bit for Soft Formation
PRODUCT INTRODUCE
Number of teeth: As the name suggests, a three-tooth roller cone bit has three roller cones, which are the primary cutting components of the bit.
Material: The tooth wheel is typically made of hard alloy or special steel to ensure its wear resistance and durability during the drilling process.
Cutting structure: Each roller bit features multiple cutting edges, which are designed for breaking and cutting underground rock formations.
Bearing system: The internal bearing of a three-cone drill bit can be either sealed or unsealed, designed to support and allow the rotation of the cones.
Sealing system: In sealed bearing drill bits, the sealing system protects the bearings from erosion by drilling fluid and cuttings.
Nozzle: A nozzle is mounted on the drill bit body, which sprays drilling fluid onto the roller cone during the drilling process to assist in cleaning the cutting surface and cooling the roller cone.
Guidance system: The three-roller cone bit is equipped with a guidance system to ensure stability and directional control during drilling.

Crossing Bit, a leading manufacturer of PDC bits and tricone bits in northern China, has exported its high-quality drill bits to more than 30 countries, demonstrating its strong market influence and exceptional product strength.
Crossing Drilling Tools has not only established a sterling reputation in the drilling, construction, HDD (horizontal directional drilling), exploration, water well, geothermal, mining, and oil & gas industries, but has also gained widespread recognition from customers for its exceptional product reliability and quality. We are committed to developing and producing a range of high-quality tools, including tricone bits, PDC bits, tricone cutters (single rollers), PDC reamers, drag bits, and HDD hole openers, to meet the diverse needs of our customers.
Our meticulously designed PDC bits are specifically optimized for directional drilling. With exceptional stability, durability, and "directional" friendliness, they are able to precisely maintain the bit's position in narrow and complex pay zones, ensuring smooth drilling operations.
This unique steerable bit technology, combined with high ROP (rate of penetration), sets Crossing Bit apart from the competition and establishes it as a leader in the industry.
