The core team of Ninestones is the first to engage in the research and development of Dome Insert in China, leading the international forefront.

In China, Wuhan Ninestones's core team was the first to develop PDC DOME INSERT, and its technology has long maintained its leading position in the world. PDC DOME teeth are composed of multiple layers of diamond and transition layers, providing higher impact resistance and are particularly suitable for use in abrasive formations. It is reported that the life of PDC DOME teeth is 5-10 times that of traditional carbide teeth, which greatly reduces drilling costs and brings revolutionary changes to the oil drilling industry.

PDC DOME teeth are not only suitable for diameter protection and shock absorption of roller cone drill bits, downhole drill bits, and PDC drill bits, but have also attracted widespread attention in the international market. The PDC DOME tooth products of Wuhan NInestones core team have been highly recognized by domestic and foreign users for their excellent performance, stable quality, excellent market service, and continuous R&D innovation.
