An auger is a device for moving material or liquid (see Archimedes' screw) by means of a rotating helical flighting. The material is moved along the axis of rotation. For some uses the helical 'flighting' is enclosed in a tube, for other uses the flighting is not encased. An integral part of a drill, the auger of the drill bit, uses this mechanism to remove shavings from the hole being drilled.

A brace or brace and bit is a hand tool used to drill holes, usually in wood. Pressure is applied to the top and the tool is rotated with a U-shaped grip. The U-shaped part is a kind of crankshaft. It gives the brace much greater torque than other kinds of hand drill; a brace can be used to drill much wider, and deeper, holes than can a gear-driven hand drill.

"Three drill bits. The first the old, bad, but not yet quite superseded pattern, which is incapable of making a straight or clean hole of any considerable depth, and which loses its original diameter both in wear and in sharpening; the second the twist drill, which compares favourably with it in every one of these respects; and the third a pin drill, for enlarging a hole already existing." —The Encyclopedia Britannica, 1903

"An ordinary vertical drilling machine, one of comparatively small size and single-geared having been chosen rather than a larger example with greater complication. When once properly started, this machine is self-acting, but for each hole the work has to be adjusted by hand so as to bring the required portion exactly under the drill spindle, and the small size of the table prevents its being at any great distance from the edge." —The Encyclopedia Britannica, 1903
