Drill bit, drilling equipment, and instrument rentals, as well as integrated drilling services for accelerated operations
Product Center
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”.

Different types of composite cutters can be selected based on the hardness and abrasiveness of the coring formation.
A force-balanced design ensures greater stability during the coring process, resulting in more uniform core samples.
The optimized overall crown shape features wider flow channels to prevent annular space blockages, enabling the drill bit to handle a variety of complex formations and significantly improving core recovery efficiency.
