DTH vs Rotary Mud Drilling for Water Wells: Bit Selection and Cost Guidance from Hard Rock Boreholes
This guide presents the bit selection logic, cost structure analysis, and regional performance data we use when specifying bits for water well projects.
Jun 13,2026
Drag bits, bore well bits, and deep well drill bits each have distinct application envelopes in water well drilling. Correct bit type and size selection — matched to formation UCS, depth interval, and casing program — reduces drilling cost per metre by 14–22% and extends average bit life by 40–60%. This guide provides specification criteria, size selection matrices, and operating parameters based on 140 water well projects across Africa, the Middle East, and Southeast Asia.

Diamond Core Bit vs. PDC Coring Bit: Which Delivers Better Core Recovery in Fractured Formations
In fractured rock (RQD < 55%), impregnated diamond core bits deliver 18–27 percentage points higher core recovery than PDC coring bits, at lower total cost per recoverable metre when infill drilling is accounted for. The economic case for diamond strengthens as RQD decreases.
