When people think of vintage hand drills, they usually imagine the brace and bit drills or the breast drills. The brace and bit drills are a U-shaped metal compound that relies on pressure and torque. These drills are used to make wide and deep holes. The user puts pressure on the knob of the drill while turning it with the bow. The drill has a gear that allows the operator to position the drill in different directions.
The other vintage hand drill is the breast drill. The user holds the drill on one side, puts his weight on top on the drill, and uses the crank to operate it. There is a nice set of gears that keep the rotation smooth on the breast drill. These drills are good for making holes in iron, steel, and really hard woods. Both of these drills have helped our civilization greatly.
