Historical information

Brace and eyed auger bits were used for boring deep holes into timber, providing space for mechanical fasteners, such as bolts or spikes. Made of iron, the pictured tool comprises a Jennings type, double twist auger bit with a threaded point to draw the bit into the wood. The other end of the shank is shaped as an eye and fitted to a hand brace. Sometimes simple cross-bars were used instead of a brace. The eye design provides greater strength than a standard auger bit. This tool’s cradle further secures the bit, preventing unwanted twisting during use. Since the late 1800’s, brace and eyed auger bits such as this were used for boring holes in fence posts, bridge building and other heavy construction.
