The shearing effect of teeth itself is also an important cutting method that cannot be ignored. Under the action of drilling pressure and drill string rotation, teeth can crush and feed into the rock, while producing a certain amount of sliding, further shearing the rock. This shear action can remove the remaining rock between the teeth, causing the rock at the bottom of the well to break completely and extend the wellbore. The cutting method of a three cone drill bit is a composite process that combines impact crushing, sliding shear, and the shear effect of the teeth themselves, allowing the drill bit to adapt to various formation types and achieve efficient and stable 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.
