Brace (tool) A brace is a hand tool used with a bit (drill bit or auger) 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 crank. It gives the brace much greater torque than other kinds of hand-powered drills. A brace and bit can be used to drill much wider and deeper holes than can a geared hand-powered drill.
