Spade bits (a.k.a. flat wood bits) have a rigid center locating point and two angled sharp, flat cutting edges that that bore holes in wood. Spade bits are designed to cut quickly and will plow through harder woods, including knots. The holes they create are typically rough and slightly burred. They get the job done well but are less accurate than the holes made by other bits. For this purpose, spade bits an excellent choice for general boring and rough carpentry but are less suitable for projects requiring precision, such as making dowel holes.
