8 1/2 XD S 5164 AS(24047) Size PDC Drill Bit with GI Cutter Grade and Ultra-Short Body Design for Directional Drilling

The XD series drill bits are directional drilling tools engineered to meet the rigorous demands of various directional well applications, including coalbed methane drainage directional wells and oil horizontal wells. Incorporating advanced drill-bit design concepts with specialized structural and material optimization, the XD series delivers exceptional rock-breaking performance under complex wellbore trajectory conditions.

• Compatible with rotary steerable systems to increase build rates, or with screw motors to enhance directional drilling efficiency
• Ultra-short body design reduces effective make-up length by 40% compared to conventional drill bits, significantly improving deviation-control capability
• Unique detent-tooth design ensures excellent tool-face stability during directional sliding operations, even under enhanced weight-on-bit conditions
• Maximum build rate capability: ≥30°/30 m when used with bent sub, and ≥15°/30 m when used with rotary steerable systems

The XD directional series is specifically designed for critical drilling sections including build-up and horizontal sections of directional wells. It can be effectively deployed in conjunction with downhole screw motors and other directional tools. In demanding applications such as coal mine gas drainage boreholes and challenging long-reach wells, this drill bit series has consistently demonstrated outstanding performance, achieving superior single-trip penetration and rapid rates of penetration.
