(from the O. Fr. guimbelet, probably a diminutive of the O.E. wimble, and the Scandinavian wammle, to bore or twist; the modern French is gibelet), a tool used for boring small holes. It is made of steel, with a shaft having a hollow side, and a screw at the end for boring the wood; the handle of wood is fixed transversely to the shaft. A gimlet is always a small tool. A similar tool of large size is called an "auger" (see Tool.).
