Import Auger — Buy in Bulk from Supplier in China

China Unibusiness Holding Co., Ltd offers a range of short augers designed for precision drilling across varied geological conditions. The lineup includes Conical Rock Augers (Single Cut and Double Cut), Flat or Butterfly Rock Augers (Single Cut, Double Cut, and Double Cut without Rock Pilot), and Flat or Butterfly Clay Augers (Single Cut and Double Cut), all engineered for drilling diameters between 500 mm and 2500 mm. Single and Double Cut Conical Rock Augers target medium to strong rock formations with compressive strengths of 15 to 60 MPa, while Flat or Butterfly Rock Augers excel in weak fractured rock, dense sand, and gravel with strengths under 5 MPa.

Each auger variant incorporates wear-resistant features such as hard facing strips on flights for longevity, with Rock Pilot or Fish-tail Pilot designs tailored to substrate type. The equipment supports custom Kelly box sizes to match project-specific drilling rigs, and all models are shipped on steel pallets or in wooden cases for secure transport. The Conical and Flat Rock Augers are optimized for uncased boreholes and secant piles, while Clay Augers with side cutters handle hard clay, silt, and medium to high-density sand and gravel.

Contractors in foundation engineering, geotechnical investigation, and infrastructure projects rely on these augers for efficient soil and rock displacement. The designs prioritize operational durability in abrasive conditions, with Double Cut configurations recommended for larger diameter applications. Buyers should confirm compatibility with their drilling rigs and request wear material specifications for high-abrasion environments.
