What is a "Forstner bit"?

A Forstner bit is a type of drill bit used to make smooth, clean, flat-bottomed holes in wood. It has a circular, toothed cutting edge with a center point that helps keep the bit steady while drilling. Forstner bits are commonly used for tasks like drilling overlapping holes, making pocket holes, or drilling through hardwoods. They are especially useful when precision and a clean finish are needed, as they create holes with very little tearing or splintering at the edges.
