DPS53-140 Reverse Circulation Drill Bit, RC Bit is a key tool for efficient hole drilling in pile foundation construction and geological exploration. Utilizing the pump suction reverse circulation principle, the flushing fluid flows downward through the annular space outside the drill rod, carrying rock cuttings upward at high speed through the inner cavity of the rod, ensuring thorough slag removal and a clean hole bottom.
This significantly improves drilling efficiency compared to traditional positive circulation methods. In applications such as large-diameter pile foundations for highway bridges and deep mining exploration, reverse circulation drilling outperforms impact drills and rotary drilling rigs in both productivity and cost-effectiveness.
DPS53-140 mm drill bit is typically paired with a 5.5-inch down-the-hole hammer, weighing approximately 16.9 kg, and is compatible with mainstream hydraulic drills and air compressors.
Built from high-quality alloy steel and tungsten carbide, the DPS53-140mm bit delivers exceptional durability and long service life. Its reverse circulation design boosts productivity by rapidly removing cuttings, ensuring a cleaner hole and reducing the risk of stuck pipe. The proprietary heat treatment provides superior hardness and wear resistance, making it a cost-effective choice for demanding mining and exploration projects.
