The water well drilling rig DTH hammer makes bits last much longer.
-
Wear-resistant bits: Uses tungsten-cobalt alloy teeth (HRC≥60). Lasts 80-100m in limestone.
-
Impact-based crushing:
Teeth crack rock instantly,
no constant grinding.
In granite,
wears 0.1mm/m vs. 0.3
mm/m for roller bits.
-
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.
