The most common type of drill bit is the 'straight shank steel twist drill' .

Other less common but still much used bits are the Brad tipped bit for woodworking and the carbide tipped bit for masonry.

The parts of a twist drill include the shank, neck, flutes, land, body clearance, and cutting edge. The cutting edge is the point of the drill bit and does the actual cutting.
