The 水井鑽機 DTH hammer differs from other tools in these ways:

 

  1. vs. Roller cone bits: Over 3x more efficient in hard rock. Less likely to fail from stuck cuttings, but slower in soft rock.
  2. vs. Auger bits: Handles harder formations. Augers only work on soil/soft rock; gravel easily damages them.
  3. vs. Hydraulic hammers: Uses 50% less energy. Higher impact frequency (1,500 vs. 500 times/min), good for deep well work.

Overall, DTH hammers offer best value in medium to hard rock. They’re the “all-rounder” for water well drilling rig.
