Step Pdc Bit for Water Well Drilling
Our company is proud to introduce our step-type PDC drag drill bits, specifically designed for water well drilling applications.
These bits are engineered for longevity and efficiency, ensuring optimal performance in various rock formations.
Key Features
Extended Drill Bit Life: Our Step Drag PDC drill bits are equipped with diamond composite inserts as the main cutting teeth, offering a service life over 10 times longer than that of tungsten carbide and 4 to 5 times longer than standard diamond drill bits.Step Pdc Bit for Water Well Drilling
High Drilling Efficiency: The large exposure of diamond (with the polycrystalline layer almost entirely exposed) ensures the bit remains sharp, significantly increasing the rate of penetration and improving drilling efficiency.
Low Pressure, Low Speed Drilling Capability: The bit crushes rock through scraping and shearing, requiring only about 1/3 of the drilling pressure needed for diamond-impregnated bits of the same diameter.
Excellent Gauge Protection: Our composite bit features internal and external diamond polycrystalline gauges that are highly wear-resistant, ensuring excellent gauge protection and efficient utilization of the cutting teeth.
Wide Application Range: Field tests have confirmed the bit’s suitability for drilling in carbonate rocks, limestone, chalk, claystone, siltstone, sandstone, and other soft to medium-hard (drillability up to grade 9) formations. The bit is particularly effective in grades 6-8 rock strata.
Cost-Effective Performance: Due to the fast drilling speed and long life, the number of trips in and out of the hole is reduced, significantly lowering drilling costs and offering superior cost-performance.
Advanced Technology and Design
High-Grade Tungsten Carbide Matrix: The bit is reinforced with a high-grade tungsten carbide matrix for added durability and wear resistance.
Enhanced Composite Inserts: Our drill bits use reinforced composite material blades designed to improve wear resistance and ensure longer service life even under strict drilling conditions.
Extra Large Water Outlet : The large water outlets ensure unobstructed water flow, preventing bit burning and eliminating the need for well washing, which achieves faster drilling speeds.
Additional Benefits
Effective Deviation Prevention: The bit has excellent directional control, preventing deviation and ensuring straighter holes.
Fine rock debris: The drill bit produces fine rock debris, which can be safely discharged with standard water-based flushing solution.
Stable quality and wide applicability: The quality of the drill bit is highly stable and versatile, with a service life of 100 to 1500 meters in various rock formations.
Why Choose Our Step Pdc Bit for Water Well Drilling?
Reduced Tripping Costs: The combination of fast drilling speeds and a long-lasting bit means fewer trips in and out of the hole, leading to significant cost savings.
Superior Durability: Our drill bits are durable and have a performance record that exceeds standard drill bits in terms of service life and reliability.
More extensive applicability: Our drill bits are highly suitable for various drilling applications and are the first choice for those who want to easily tackle challenging formations.
