Countersink

Countersink | Drill & Tap

A countersink is a specialized tool used to create a conical recess in a material, allowing the head of a screw or bolt to sit flush with or below the surface. Countersinks are commonly used in woodworking, metalworking, and construction to ensure a smooth finish and prevent snagging on protruding screw heads. Available in various sizes and shapes, they can be used with hand drills or drill presses for precision. Made from durable materials such as high-speed steel (HSS) or carbide, countersinks are essential for achieving clean, professional results in assembly and finishing tasks, making them a valuable addition to any toolkit.
