Premium Cutter Technology

The 1308 PDC cutters integrated into this bit are crafted from premium diamond composite materials, ensuring exceptional hardness, heat resistance, and wear resistance. These cutters are strategically arranged on the blades to maximize rock interaction, reduce friction, and enable fast, efficient penetration through tough rock layers. With their long-lasting edge retention and thermal stability, the cutters help minimize the number of trips needed to change bits, thereby saving time and reducing operational costs.

Structural and Hydraulic Design

The steel body of the bit provides superior mechanical strength, ensuring it can withstand impacts, torque, and downhole stress. The four-blade (or wing) configuration enhances balance and wear distribution, while also supporting smooth drilling dynamics. Additionally, the four nozzles are carefully positioned to provide efficient fluid flow across the bit face. This optimized hydraulics ensures effective cleaning of the cutting structure, cooling of the PDC cutters, and removal of rock cuttings from the wellbore, especially in abrasive or sticky formations.

Operating Parameters

• Rotational Speed (RPM): 60–260 revolutions per minute

• Weight on Bit (WOB): 30–140 kN/mm

This bit offers a broad range of operational flexibility. By adjusting the RPM and WOB within the specified range, drillers can optimize performance based on real-time drilling conditions and formation responses. It’s crucial to maintain these parameters within recommended limits to avoid overheating, cutter damage, or loss of drilling efficiency.

Recommended Applications

This PDC bit is especially suited for medium to medium-hard formations with high compressive strength and abrasiveness. Ideal formations include:

• Dolomite – Dense and brittle, requiring high-quality cutters for sustained drilling.

• Limestone – Especially hard or fossil-rich variants that can be abrasive.

• Anhydrite – Often encountered in salt and sulfate zones, known for being tough on cutters.

• Sandstone – Particularly quartz-rich or cemented sandstones, which are both abrasive and tough.

The design of this bit allows it to handle variations in these formations while maintaining cutting speed and bit stability.
