Dormer Sand Augers 1m Various Diameters Painted Steel
Sand Augers come in one design (with some minor variations) for drilling or sampling sands. 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. If debris, other hard objects, or bands of soil may be encountered, we suggest the Heavy-Duty version made from thicker steel (the same thickness as equivalent-sized soil augers). The item code for HD versions has “/HD” at the end, e.g., SA7510C/HD.
Item Code SA
These were originally designed to sample for minerals in beach sands but are now 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.
In South Africa 12 men drilled to a depth of 100 metres in one day, in ideal conditions.
