Conventional Hybrid Bit Series
The rolling tooth-wheel stamping pre-breaks the rock, complemented by the fixed PDC teeth that scrape and cut, creating a synergistic effect that significantly boosts rock-breaking efficiency while reducing energy consumption.
For highly abrasive, hard formations such as granite, composite drill bits demonstrate superior durability and sustained rock-breaking performance, outperforming conventional PDC drill bits.
Additionally, optimizing the arrangement density and geometry of the hard alloy teeth on the tooth-wheel design enhances both single-bit penetration rates and overall drilling efficiency.
Size Range：5 7/8”~26”.
PDC optimizes the matching with roller cone cutting profiles, effectively reducing and mitigating torque, thereby enhancing the controllability of the drill bit's sliding tool face.
Through force-balanced design analysis of the cutting structure, the drill bit achieves improved operational stability, minimizes stick-slip effects, and boosts its directional guidance performance.
Combining active and passive gauge protection enhances overall build rate, lateral cutting efficiency, and directional control.
Additionally, the drill bit features a multi-point gauge and balanced positioning system for both gauge protection and centralization, ensuring enhanced stability and superior adaptability during build-and-ride drilling operations.
Size Range：5 7/8”~17 1/2”.
