Edelman auger combination type (left) and
Riverside auger (right).
A short upper part with beating head is used to drive or hammer the auger into the soil. A special impact-absorbing hammer
is used to pound the auger. The steel hammer is impact-absorbing because its head contains lead bullets flowing in the
direction of the stroke upon impact. Its nylon cups prevent damage to the auger.

Edelman auger and Riverside auger
The Edelman auger in the set (see figure) is a combination type auger. Its auger body is conical in shape and consists of
two blades (1) joined in a bit (2). The top of the blades is welded to a bracket (3), which is connected to the auger rod (4).
The blades are vaulted and when entering the soil the sample is dug up and evenly guided into the inside of the auger
body. The vaulting of the blades not only promotes digging up but also ensures a firm grip of the sample while permitting
easy emptying of the auger body.
The Edelman auger combination type in the set has a 10-cm diameter (measured diagonally between the blades at the
broadest part of the auger body) and the blade width measures 50 mm.
The blades permit a good hold of moderately cohesive soils, while cohesive soils can easily be removed.
The auger body of the Riverside auger (see figure) has an open tube
(6) with two beak-like bits at its base (5) and a bow bracket (7) at its
top, which connects to the auger rod (8). The extremities of the bits
are skewed and scrape the soil, pressing the sample evenly into the
tube. The diameter of the auger bits slightly exceeds the tube’s di-
ameter so as to reduce friction between soil and tube to a minimum.
The Riverside auger in this set has a 10-cm diameter.
The standard upper part (see figure) has a detachable, synthetic
handle and is used with the Edelman auger and the Riverside auger.
