When was the Forstner bit invented?
In 1886, Forstner patented the Forstner bit. The bit was revolutionary as it did not feature the lead screw (which Forstner called the "gimlet-point") or the cutting lips of more conventional wood boring bits, and thus proved especially useful to gunsmiths and high-end woodworkers.
How did a Forstner bit get its name?
Another example eponymous product, the Forstner bit, was named for Benjamin Forstner (1834—1897). This bit-- it forms flat-bottomed holes -- is widely used by woodworkers.
What is another name for Forstner bit?
Because of the same reason, they are also called paddle bits by some people. They're the cheapest of the three and are ideal for boring rough holes through even thick pieces of wood.
What is the purpose of a Forstner bit?

Most Forstner bits are made from high-speed steel, which is sometimes called high carbon steel. Carbide-tipped versions are available and more durable, but they are more expensive.
How many teeth does a Forstner bit have?
The standard Forstner bit has two individual teeth on the perimeter. These teeth are located directly opposite each other and are designed to cleanly slice through wood fibers as they rotate. The width of this tooth varies—on some, it’s slender, while on others it might be as wide as ¼ the drill bit circumference. A longer edge increases cutting speed and a bar across the center pushes the waste out of the way as the bit rotates. A central spur, which is just a fraction of an inch longer than the teeth, allows for precise positioning.
