Combination Edelman Augers are used in a variety of soil conditions. They retain sandy material well, and more cohesive mud and clay soils can be easily removed from the body. A One-Piece Combination Edelman Auger is also available.
Edelman Augers feature Eijkelkamp's quality Edelman Auger bodies combined with the versatility of the 5/8" threaded, Signature Series threaded, Quick Connect, and Hex Quick Pin connection systems. Eijkelkamp Edelman Augers are widely used for the study of soil composition, soil profiling, and soil mapping. They feature a screw-like point at the base of the Auger that enters into the soil as you push and turn the Auger clockwise. The soil sample is guided into the Auger by two vaulted vertical cutting blades. The vaulted design promotes soil digging and ensures a firm hold of the sample in the Auger.
Edelman Augers utilize drilling bits made of untreated steel to avoid contamination of collected soil samples. There are four types of Edelman Augers: Combination, Clay, Sand, and Coarse Sand. The Combination Edelman Auger is the most commonly used, but the Auger type should be chosen with respect to the soil conditions in order to achieve optimal results.
