Spiral auger


Spiral auger that functions similarly to a corkscrew, used to penetrate hard soil layers. Available in 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


The spiral auger is not use to cut of soils, but rather penetrate hard layers with a functionality that resembles a corkscrew. The spiral auger has a negative end, which means that the centre of the auger end is whetted away.

This type of auger is seldom used for profile research and soil mapping. Rather, its use is confined to augering through very hard layers, such as bore ore, brick layers, chalk and lime profiles, in combination with other auger types. 

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.
