Milled Tooth 16 Inch Tricone Rotary Drill Bits IADC 617

Sliding shear is also an important cutting method for three cone drill bits. When the drill bit is drilling into high plastic rock layers, its cutting structure will produce relative sliding relative to the teeth. This sliding causes the cutting teeth of the drill bit to come into contact with the rock at a certain point in the wellbore, and its rotational speed is less than the revolution speed, resulting in shear fragmentation. Due to the fact that the shear strength of rocks is usually lower than their compressive strength, the efficiency of shear rock breaking is often greater than that of impact rock breaking. In addition, sliding shear can be more effectively achieved by designing super top, complex cone, and shifting axis for the cone bit body.

Company Profile

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.
