Definition

A counterbore can refer to a cylindrical flat-bottomed hole, which enlarges another hole, or the tool used to create that feature. A spot face is a very shallow counterbore. A counterbore hole is used when a fastener is required to sit flush with or below the level of a workpiece's surface.
