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
a tool for boring holes in soil; it is frequently used for extracting samples of soil for tests
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
