6 Inches

6 inch drill bits (152.4mm) are among the most widely used sizes in shallow to medium-depth drilling operations. This diameter strikes a practical balance—large enough for adequate fluid flow and cuttings removal, yet small enough to keep drilling costs manageable. You'll find 6" bits in water well drilling, geotechnical investigation, mining exploration, and shallow gas/oil wells across job sites globally.

Core Advantages:

- Available in PDC, tricone (TCI and steel tooth), and drag bit configurations

- Standard API REG pin connection for broad rig compatibility

- Ideal borehole diameter for 5" or 5-1/2" casing programs

- Optimized for rotary speeds of 60-120 RPM in typical formations

- Compact size allows use on smaller, lower-cost drilling rigs

- Suitable for both vertical and limited directional drilling applications

Q: What weight on bit (WOB) should I run for a 6-inch PDC bit?

A: For most 6" PDC bits, start with 8,000-15,000 lbs WOB in soft to medium formations, adjusting based on torque response and penetration rate. Always follow the manufacturer's recommended operating parameters.
