An Archimedean screw is another name for an Archimedes' screw, a screw which, when twisted inside a cylinder, raises water from a lower level to a higher level, allowing irrigation of fields.
The twist drill uses flutes that act as an Archimedean screw to lift swarf from the hole.

A screw with a slot in it.
screw
That would be a "phillips" heades screw.
Its Purpose was to irrigate and lift water From mines and Ship Bilges
The Water Screw helped to bring water from a lower level to a higher one. :)[ADDED] It's normally called the "Archimedean Screw".

An Archimedean ordered field is an ordered field which satisfies the axiom of Archimedes.
The Archimedean screw can be constructed using two simple ideas. The first is a screw, which in an inclined plane wrapped around a central core or axis. The second idea is to closely confine the screw by placing it inside a cylinder the length of the screw. One variation of the Screw is to coil a flexible tube around a core shaft. As the shaft is turned, the tube will work in the same way and lift the water up, with the problems caused by an actual Screw's operation. A picture is probably worth a thousand words at this point, so drop down below and find a link to an explanation of the device. It comes complete with an aplet showing the the machine in operation. Check out how it is set up and how it works.

An Archimedean property is the property of the set of real numbers, that for any real number there is always a natural number greater than it.
No, Archimedes did not invent the lawn mower even though one of his attributed inventions paved the way for that invention 2,000-plus years later. The lawn mower invented by an English textile mill engineer in 1830 had the name Archimedean revolving cutter mower. The mower in question included a revolving screw-shaped blade inside a cylinder, considered the essential design of the Archimedean screw attributed to Archimedes' (287 B.C.-212 B.C.) inventiveness.
Yes, in fact in some of the older cities you can still find the Archimedean screw that allowed water to flow up hill. This was in use all over Greece for nearly 2,000 years!
