1.Equipped with wear-resistant tungsten carbide teeth, excellent cutting performance in soil, sand, clay and weathered rock, effectively prevent bit sticking.
2.Optimized three-wing flushing channel design, smooth cuttings discharge, greatly improve drilling efficiency for reverse circulation drilling projects.
3.Compatible with DTH hammer & concentric casing system, ideal for borehole drilling, casing follow-up drilling in unstable and easy-collapse formations.
4.Wide range of optional diameters and thread connections, widely used in water well drilling, solar pile foundation, anchor hole and geotechnical engineering.
5.Integrated high-strength bit body, stable operation with low vibration; cost-effective choice for soft & medium formation drilling.
