Latest Patents

Zhiming Shi holds a patent for a "Fixed cutting structure-composite cone drill bit." This invention includes a drill bit body, a fixed cutting structure, and at least one cone. The cone is rotatably connected to the drill bit body through a bearing structure. The design ensures that the distance from the outermost tooth or back cone of the cone to the front side surface of the fixed cutting structure is ≤ πR/3, and the distance to the rear side surface is also ≤ πR/3. This innovative design minimizes the gap between the cone and the fixed cutting structure, allowing for a smooth transition between cutting structures.
