17 1/2“（444.5mm）IADC 637 TCI Drilling Bit Tricone

The drill bit mainly consists of four parts: the tooth palm body, the roller body, the bearing system, and the nozzle.

Its working principle is: under the action of drilling pressure and drill string rotation, the teeth on the roller cone impact and press into the formation, achieving crushing effect; At the same time, the sliding of the roller generates shear force, which breaks the rock between the teeth; The high-speed jet sprayed from the nozzle plays a role in assisting erosion and cleaning the bottom of the well.

According to the type of bearing, it can be divided into two categories: rolling bearings and sliding bearings; According to the method of tooth fixation, it can be divided into two categories: inlaid teeth (hard alloy teeth) and milled teeth (steel teeth). The International Association of Drilling Contractors (IADC) has developed a three digit coding standard for classifying and selecting drill bits based on tooth type, formation adaptability, and structural characteristics

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.
