Any boring bit that acts like a rotary chisel to shave out the wood as the tool progresses The screw-shanked spiral auger that lifts the shavings out of the deepening hole did not become common until about the 1820s Before this time, shell or nose augers required a centering, starting hole gouged into the surface of the wood before they could be started
Device for lifting materials Uses a rotating, enclosed screw which lifts the material as a result of the screwing action Used with some success for lifting fish and water together Not as flexible as a fish pump in that the angle of lift is restricted and means that the auger sometimes takes up too much space One advantage is that it can gently handle very large fish (in excess of 5kg), which most other types of fish transportation systems will not Also used for conveying feed to and from hoppers
a rotary drill for soft materials that utilizes a screw device to penetrate, break, and then transport the drilled material Auger-type devices are popular in soft coal To aid penetration and decrease wear on the auger rods, a hard-faced bit is used at the contact between drill and fresh material
a tool used for making a hole in wood or in the ground (a nauger, mistaken for an auger; nauger (11-17 centuries) from nafogar, from nafu + gar ; because it was originally used to make the hole in the hub of a wheel). Tool (or bit) used with a carpenter's brace for drilling holes, usually in wood. It looks like a corkscrew and produces extremely clean holes, almost regardless of how large the bit is. Expansive auger bits have adjustable blades with cutting edges and spurs that can be extended radially to cut large holes. Large augers are used to bore holes in soil for fence posts and telephone poles, or in ice for ice fishing. Horizontal augers as much as 8 ft (2.5 m) in diameter are used in coal mining
The Pierre Auger Project (named for the famous French physicist) Auger will consist of two giant air shower arrays One is under construction in Argentina The second will be in the northern hemisphere Each will cover 3000 km2 with 1600 water Cerenkov tanks (and associated fluorescence detectors) that can record about 6000 cosmic ray showers per year with energies above 1020eV The main goal is to study the origin of ultra-high-energy cosmic rays This international project is led by Jim Cronin For more information, see J W Cronin, Nucl Phys Proc Suppl B471, 135 (1996); A A Watson, Phys Rept 333-334, 309 (2000); and http: //www auger org
A rotating, screw-type device that moves material through a cylinder In alcohol production, it is used to transfer grains from storage to the grinding site to the cooker
A tool for boring holes in wood, having a long pointed shank with a cutting edge and a screw point and a handle fixed with right angles to the top of the shank
An instrument for boring or perforating soils or rocks, for determining the quality of soils, or the nature of the rocks or strata upon which they lie, and for obtaining water
