The Dual-System Bit Brace

Dual-System Bit Brace

As early as 2500 BC, using a bow drill was the primary means of boring or drilling a hole. The auger was also used extensively by the Romans, and widespread usage of the hand and breast auger has been documented throughout northern Europe during 1000 AD to 1500 AD.

The 1500s saw the introduction of a new boring tool — a brace employing a rotary sweeping motion with a fixed pad or revolving head. The exact year it was thrust on the woodworking world is unknown. However, the 1982 salvage of the Mary Rose, an English warship launched in 1511, and the subsequent discovery of the ship's carpentry tools included an example of the sweep-type brace. Other examples of this tool were documented in northern Europe during 1450 to 1500.
