Generally speaking, in agriculture, the auger will be used to lift, transfer and/or process loose grain and hay. But note that a utility auger will be utilized in a whole host of other industries as well, to lift, process and distribute sawdust, pea coal, plastic pellets and a whole host of other materials too.
One online record discovered shows that there are over four hundred auger sizes out there. This just goes to show the scale in terms of different industries being serviced, and not just primarily agriculture. Traditional agricultural augers handle grain. But augers built as combines can be manipulated as feed grinders.
In other industries, augers are used for digging holes. The auger specific to this task is known as an earth auger. Augers are handheld devices, but they are also powered. For the purposes of digging holes in the ground, you will therefore have the use of a handheld power earth drill. Other definitions passed around are that of a mechanized post hole digger and a soil auger. Not powered, the digging auger is turned manually.
Powered augers are powered by electricity. They can also be propelled through the use of an internal combustion engine. In the agricultural space, such an engine will usually be attached to the farmer’s tractor. Handheld augers can also be used for domestic purposes, with home gardening being the most obvious example.
Augers are also built out of wood. A screw is used to pull the auger into the wood. With such a material, a cutting lip slices out the bottom of a hole. An auger bit, used in a brace, has cutting spurs which are used to cut clean circles at deeper than usual depths. And for the purposes of augerating deep foundations, augers will be used in the construction business as well.
