The CBT four-wing PDC drill bit is designed for efficient drilling in a range of rock formations. It features four cutting wings equipped with Polycrystalline Diamond Compact (PDC) cutters, which shear the formation during drilling.

The four-wing configuration provides a balanced cutting structure and supports stable drilling performance. PDC cutters offer high wear resistance and efficient rock-cutting capabilities, making this bit suitable for applications where consistent penetration and extended service life are required.

Available in multiple diameters and thread connection options, CBT four-wing PDC drill bits can be selected according to drilling equipment, borehole dimensions, and formation conditions.

Key Features of CBT Four-Wing PDC Drill Bits

1. Four-Wing Cutting Structure

The four-wing design distributes PDC cutters across four cutting sections, providing a balanced cutting arrangement. This structure helps maintain drilling stability and supports efficient rock removal.

2. High Penetration Efficiency

PDC cutters shear rock formations rather than relying primarily on impact crushing. This cutting mechanism supports a high rate of penetration (ROP) in suitable formations and helps improve overall drilling efficiency.

3. Wear-Resistant PDC Cutters

The PDC cutting elements provide high hardness and abrasion resistance. Their wear-resistant properties help maintain cutting performance during extended drilling operations.

4. Multiple Diameter and Connection Options

CBT four-wing PDC drill bits are available in a range of diameters to accommodate different drilling requirements. Multiple API thread connections are also available for compatibility with different drilling equipment.

Available Diameters and Thread Connections

CBT four-wing PDC drill bits are available in the following diameters:

Diameter range:

114 mm, 120 mm, 127 mm, 140 mm, 143 mm, 152.5 mm, 165 mm, 171.5 mm, 190 mm, 196.5 mm, 200 mm, 216 mm, 241 mm, 250 mm, 305 mm, 355 mm, and 381 mm.

Thread connection options:

• For diameters below 165 mm: 2-7/8" and 2-3/8" API connections.

• For diameters of 165 mm and above: 3-1/2" and 4-1/2" API Reg Pin connections.

Please confirm the required diameter and thread connection when placing an order.

Applications

Four-wing PDC drill bits are used in drilling operations involving suitable soft to medium-hard rock formations. Typical applications include:

• Oil and gas drilling.

• Water well drilling.

• Geological exploration.

• Mining and other industrial drilling operations.
