These auger heads are suitable for boring in cohesive soils or sands and gravels. The soil augers are constructed of heavy duty steel plates forming an open tube partly interlocked at the cutting end. Gravel augers comprise a one piece steel casting with a spiral point and two plates designed to close when lifting samples from the borehole. The Dutch Auger is of similar construction to the Soil Augers and is particularly useful in very fine silt-clay sands.
Thiis range of durable augers is based on a threaded joint system enabling items to be interchanged and extended to any depth required.
