Roller Bits: Best for Water Well Drilling Rigs in Sand
Water well drilling rigs rely on roller bits—ideal for sand layer drilling.water well drilling rig
Roller bits have multiple rolling cutting teeth. They crush sand grains of different sizes evenly. Alloy teeth resist wear from constant quartz sand abrasion.
For medium-fine sand layers, choose wedge-tooth roller bits. Shearing between teeth boosts crushing efficiency significantly.
In gravel-mixed sand layers, insert roller bits stand out. Hard alloy teeth handle gravel impacts effectively.
Tips for choosing roller bits for water well drilling rig:
- Check bearing sealing closely. Stop sand from entering to prevent early damage.
- Adjust bit pressure drop by sand density. Match it to the layer’s tightness.
- Use high-pressure drop for dense sand. Lower pressure for loose sand to avoid over-disturbance.
This ensures smooth operation for water well drilling rig in tricky sand conditions.
