Summary: Creating conical holes for screws.

Countersinks are cutting tools used to create a conical or beveled depression at the opening of a drilled hole. This depression, known as a countersink, is designed to allow the head of a screw or rivet to sit flush with or below the surface of the material. By creating this recess, countersinks provide a smooth and aesthetically pleasing finish, preventing the fastener head from protruding and interfering with other components. They are commonly used in woodworking, metalworking, and construction.
