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.
