Select carbide button and DTH drill bits for 15,000–30,000 psi mining exploration while protecting gauge and sample quality.

16 Jul 2026

Select tricone or DTH button drill bits for consolidated water-well rock using approved WOB, RPM, IADC, and air-pressure ranges.

16 Jul 2026

Choose drag or tricone drill bits for unconsolidated water-well ground while controlling packing, rolling gravel, RPM, and WOB.

16 Jul 2026

Choose drag or clast-matched tricone drill bits for uncemented alluvium and gravel while controlling packing, circulation, and bore stability.

16 Jul 2026

Select PDC, strength-matched tricone, or Button/DTH bits for well-cemented sedimentary rock using UCS, quartz, cleaning, and gauge evidence.

16 Jul 2026

Plan PDC, tricone, or Button/DTH drill-bit transitions for alternating Soft and Hard beds using lithology, torque, vibration, and gauge evidence.

16 Jul 2026

Select Button/DTH or strength-matched tricone bits when quartz exceeds 20%, separating abrasive wear risk from UCS and monitoring gauge loss.

16 Jul 2026

Select Button/DTH or IADC 637 tricone drill bits for 15,000–30,000 psi granite, basalt, and quartzite with gauge and cleaning controls.

16 Jul 2026

Choose PDC, 437/447 tricone, Button/DTH, or limited drag structures for 4,000–15,000 psi sandstone, limestone, and dolomite.

16 Jul 2026

Select PDC, milled-tooth tricone, or drag drill bits for sub-4,000 psi clay, shale, and sand while controlling cleaning and gravel risk.
