Impact Bits: Strong for Water Well Drilling Rigs in Coarse Sand
Water well drilling rigs rely on impact bits in coarse and gravelly sand layers.
High-frequency impact plus rotation breaks sand particle bonds effectively. They excel in sand with particles over 2mm.
DTH impact bits use compressed air for cuttings. Great for dry area drilling—less water, no mud pollution.
Tips for impact bits with water well drilling rigs:
- Choose cross-shaped bits for boulder-containing sand. Boost breaking power for large particles.
- Adjust impact frequency by sand density. 30-40 times/min for loose sand, 50-60 for dense.
- Focus on bit guidance. Avoid hole deviation from uneven impact force.
This enhances performance for water well drilling rigs in tough coarse sand conditions.
