Product Description
Water Well Impact Drill Bit for Rock Layers with High Penetration Rate
| Drill bit name | Water well impact drill bit |
| Material | Tungsten Carbide |
| Diameter | 76mm-450mm |
| Production cycle | 5-7 days |
| Country of origin | China |
| Application industry | Water well industry |
Drill Surface Shape Selection
- Downward center position: For high permeability in soft to medium hard and fractured rock formations. Provides low to moderate air pressure with maximum hole deviation control.
- Concave surface: Designed for medium hard and homogeneous rock formations. Offers good hole deviation control and excellent flushing ability.
- Convex surface: Delivers high penetration rates in soft to medium hard formations at low to moderate air pressure. Most resistant to steel washing but with poorer hole deviation control.
- Flat drill bit: Ideal for hard to very hard and abrasive rock formations in high-pressure applications. Provides good penetration rate and steel washing resistance.

Manufacturing Advantages
- Advanced production equipment and experienced research team
- Highest quality raw materials and strict quality control
- Custom manufacturing available for OEM requirements
- Advanced production technology and rigorous testing procedures
Maintenance Guidelines
Post-Operation Care
- Thoroughly clean all surfaces, especially chip grooves, using a wire brush
- Rinse with clean water if exposed to corrosive liquids and dry completely
- Inspect for damage - minor chipping can be polished with an angle grinder
- Discard bits with loose alloy teeth or cracked welds immediately
Storage Recommendations
- Apply anti-rust oil on steel surfaces, especially threads and welds
- Store in a dry toolbox away from other hard objects
- Protect alloy teeth and cutting edges from impact
Core Operating Principle:
Follow the "adaptation, cooling, stabilization, and cleaning" principle: select proper drill bit model, ensure cooling/lubrication, control force/angle, and address abnormalities promptly. Proper maintenance can extend drill bit life 2-3 times while improving efficiency and safety.
