Will mismatched tool sets cause drilling failure?

Our reaming shells follow DCDMA standard threads, fully compatible with AQ/BQ/NQ/HQ/PQ series core barrels and bits, avoiding connection mismatch issues.

What's the impact of unstable borehole on core sampling?

Unstable holes lead to core breakage and low recovery rate. The reamer straightens the borehole, guarantees complete rock core and improves sampling accuracy.

Product Q&A

Q:What problems does a reaming shell solve during core drilling?

It mainly fixes borehole shrinkage, irregular hole diameter and hole deviation. It keeps the borehole standard round, stabilizes the hole wall, and ensures smooth running of subsequent drilling tools.

Q:Why do we need a reamer instead of using a drill bit alone?

Single drill bit cannot maintain full gauge for long. The reaming shell protects the drill bit and core barrel from severe wear, reduces tool damage and replacement frequency.

Q:How does it improve low drilling efficiency in hard rock?

Optimized spiral water channels and high-hardness diamond cuttings remove rock debris quickly, avoid bit balling and stuck pipe, greatly boost drilling progress.

Q:Can it work in broken & complex formations?

Yes. Its reinforced body and reasonable structural design prevent hole collapse, effectively adapt to fractured rock, loose soil and mixed strata.

Q:How does it cut down overall drilling costs?

Long service life lowers tool consumption. Stable borehole reduces tripping times, downtime and labor cost, saving comprehensive expenditure for projects.
