Dormer Soil Augers
A variety of different Auger heads are available suitable for sand or soil, in addition to Jarret and Spiral style heads. Extension rods come in 1.0 m lengths and head diameters can be 50, 62, 75 or 100m. Standard sizes are 50mm (2″), 62mm (2½”), 75mm (3″) and 100mm (4″) and some others made-to-order.
Standard versions of the Sand Augers are made from very thin steel for use in clean sand and if debris or other hard objects or bands of soil may be encountered we suggest the Heavy Duty version made from thicker steel (same thickness as equivalent sized soil augers).
These were originally designed to sample for minerals in beach sands but now are used extensively for drilling and sampling in very sandy friable soils. A 75mm (3″) diameter sand auger will penetrate 30 cm in about 4 turns, which fills the auger. In good conditions, one man can drill 10 metres in an hour, two men can drill 20 metres in two hours and 40 metres takes most of the day.
Options: Sizes; Length; From thicker steel; Hot spray-on hardening. Also available made from stainless steel
SOS Series: This is our most popular auger which is a general purpose design to handle most soil conditions, even very sandy soils.
SOD Series: This new soil auger was developed to achieve better penetration in hard dry soils and by doing so requires extra effort to turn it.
SON Series: It is a 2 flat cutter, single slot design.
SOC Series: This soil auger was developed primarily for its easy to clean features when used in sticky wet soils.
JA Series: For taking small samples but may be subject to sample mixing causing contamination.
SP Series: These are used to drill hard compacted soils or decomposed rock. They drill faster and are stronger than the soil augers but require greater care for accurate sampling.
