Trusted Hammer Bit from Central Drill

Begin with expected hardness, abrasiveness, and water content, then match face style and carbide grade to those factors. Verify that your compressor can supply the air volume and pressure the bit-hammer combination requires, or you risk poor cuttings evacuation and premature wear. If you’re dealing with interbedded layers, we can recommend compromise geometries, contingency sizes, and operating windows to keep penetration steady, safe, and predictable.

Seat the bit with a brief break-in, then raise impact energy and RPM gradually while monitoring torque, return cuttings, and vibration. Maintain adequate airflow and correct lubrication; clean flushing reduces regrind, heat, and spalling, extending carbide integrity and gauge. Avoid dry firing, bouncing off bottom, or excessive rotation without impact, and inspect threads, shanks, and couplings at every trip.

Yes, we provide professionally rerun bits that undergo gauge measurement, thread inspection, and detailed visual checks for cracks, cone wear, and braze integrity. We document findings, photograph key features, and confirm compatibility, giving you predictable performance at a lower cost per foot. For time-critical jobs, we can stage multiple sizes, pack for export, and coordinate certificates, customs, and delivery milestones.
