Product Q&A

Q:Which reverse circulation hammer matches QIDELI RE004 & RE542 drill bits?

They are fully compatible with QIDELI NRC series reverse circulation DTH hammers, perfectly matched for deep geological core sampling drilling.

Q:What diameter sizes do RE004 and RE542 bits support?

RE004 head diameters: 115/121/124/127mm; RE542 head diameters: 121/124/127/133mm, all with 8 splines and 2 exhaust holes.

Q:Will the drill bit pollute my rock core samples during drilling?

No. Adopting patented drop-center face structure, the bits separate debris and core samples effectively to guarantee uncontaminated intact samples.
