High-precision sealing design: The ferrule-type structure uses a tightened nut to deform the ferrule, allowing it to bite into the pipe wall and create a circular sealing groove—ensuring a leak-free connection.
Smooth transition reduces losses and boosts efficiency; the gradual inner-wall design significantly minimizes fluid turbulence and pressure drop.

The matrix body PDC bit not only applies the lDS system to optimize the cutter arrangement, hydraulic, and mechanical models but also uses advanced matrix body formulations to ensure the strength of the bit body. The high-precision and high. performance rubber mold guarantees the accuracy of the cutter holes and crown shape of the matrix body PDC bit, meeting the high-quality customization needs of domestic and international customers.
The internal cone features a concave design, reducing the center height of the blade wings and distributing the drilling load more evenly, thereby enhancing stability.
The symmetrical blade wing arrangement widens the blade channel, improving chip-removal efficiency and preventing buildup at the bottom of the wellbore—thus avoiding repeated cutting.
Additionally, the large-angle nozzle bore angle facilitates effective flushing of the well bottom, helping to prevent bit sticking.
The pilot shoe center works in coordination with the reaming body center, while the arc length around the reaming body is precisely controlled by the wing angles, ensuring stable wellbore enlargement.
An IDS intelligent tooth-placement design is employed to meet the principle of minimum bottomhole force balance, enabling the drill bit to achieve smooth cutting at the bottom of the well.
Equally spaced and narrowly designed cutting wings maximize the flushing area of the flow channels, significantly enhancing overall rock-breaking efficiency.
The gauge protection layer is made from TSP polycrystalline material and features an anti-rotation design, which reduces vibration-induced wear and extends the drill bit's service life.
Size Range：3 1/4”~26”.
