DGSI Hand Auger with unique hard-faced and cupped blades is ideal for boring shallow holes in fine grained soils. Little effort is needed to turn the auger and advance the hole as the blade diameter exceeds the bucket diameter by 1 in. (2.54 cm) to produce a 3-1/4 in. (8.2 cm) diameter hole.

Durham Geo Slope Indicator Hand Auger features:

Heavy gauge, heat treated carbon steel bucket for long life with cupped blades of unique design to facilitate hole advancement
Zinc electroplated for rust resistance
Quick connect pins avoid use of wrenches
All stainless steel hand auger assembly is
available for environmental sampling
A special “windowed bucket” is available for use in sticky clay soils.

AMS Hand Augers

The AMS Hand Augers with threaded connections are available in models designed for regular, mud/clay and sandy soils. These Standard Augers are made with a stainless steel cylinder, formed carbon steel bail and hand forged, heat treated, high carbon steel bits. The bits dig in as the auger is turned and cut a hole from 3/8 to 3/4 in. (1-2 cm) larger than the cylinder to reduce the effort required. Available in nine cylinder sizes from 1 1/2 to 6 in. (3.8 to 15.2 cm), popular sizes are detailed in the table.

A threaded coupling is used to connect the auger head and cross handle to the extension. The Extensions are available in lengths of 3, 4 or 5 ft (91,122 or 152 cm) and are made from strong, but lightweight, chrome molybdenum steel. Select from the available standard, rubber coated or ratcheting cross handles. Available in stainless steel.

The Density Drive Sampler is used to determine the in-place density of soil by driving a thin-walled tube to obtain a soil sample of known volume.

The Sampler consists of a zinc plated steel drive head and sliding 10 lb hammer. The drive head is provided with a shock spring. Drive tubes are zinc plated and supplied separately.

Drive Tube Samplers are available in three sizes:
- 2 in. by 6.25 in. (0.01 ft3)
- 3 in. by 2.75 in. (0.01 ft3)
- 4 in. by 5 in. (0.033 ft3).
