Stony soil auger

Variations available

Stony soil auger for use in coarse, gravelly soils with stones. Available as one-piece auger or bottom part with various diameters and connections.

  • High tensile strength forged auger bodies
  • Perfect auger body shapes for optimal drilling
  • Non toxic steel for all types of analyses
  • Rapid connectible extension rods


This auger is used for soils with a large gravel content. The auger body for stony soils consists of a heavy steel strip, vaulted all along, which is bent double by forging. The pointed cutting section of the strip is bent outward, thus creating a hole significantly wider than the average body diameter. The stony soil auger is used when the Riverside auger is not yielding adequate results in coarse gravel soils.

To achieve optimal results, the auger type should be chosen in respect of the soil type in question.

Augers should be left to air-dry after use and decontaminated with soaps. Rust will naturally appear on these augers, read the brochure for more information.
