Special PDC Bits: Ideal for Low Gravel Strata
Water well drilling rigs gain new options with special PDC bits for low gravel. bits
For <20% gravel mixed layers, enhanced PDC bits optimize blade layout and inserts. Staggered blades reduce direct gravel impacts.
Ultra-coarse diamond inserts boost impact toughness by 30%, handling small gravel hits.
Tips for water well drilling rig PDC bit:
- Use for fine gravel <5mm. Drill 20-30% faster than roller bits here.
- Keep pressure at 8-12 tons, speed 60-80 rpm. Avoid insert cracking from high parameters.
- Adopt “low pressure, high speed” in uneven gravel. Buffer impacts via blade flexibility.
Limit use with large gravel—pair with pre-crushing for best results.
