Durability: DTH Hammers Extend Bit Life for Water Well Drilling Rigs

News 32 Views
The water well drilling rig DTH hammer makes bits last much longer.

 

  1. Wear-resistant bits: Uses tungsten-cobalt alloy teeth (HRC≥60). Lasts 80-100m in limestone.
  2. Impact-based crushing: Teeth crack rock instantly, no constant grinding. In granite, wears 0.1mm/m vs. 0.3mm/m for roller bits.
  3. Right bit selection: Sharp teeth for hard rock, flat for broken rock. Extends life by 30%+.

 

One project matched bits well, drilling 90m/bit (up from 60m), cutting costs 25%. The water well drilling rig saves on replacements.
