Countersink is a verb and a noun that is commonly used in woodworking, metalworking, and construction. It refers to the process of creating a tapered hole or depression into a material, typically a wood or metal surface, to allow the head of a screw, nail, or bolt to sit flush with or below the surface.
As a verb, countersink refers to the action of using a special tool called a countersink bit or countersinking tool to cut or shape the conical recess. The tool is usually rotated in a rotary drill or power tool, and it gradually chips away the material and widens the mouth of a pre-drilled hole. This preparation is essential to prevent the screw or bolt head from protruding above the surface, which may cause interference or damage.
As a noun, countersink is the depression or taper itself that is created by the countersinking process. It can be described as a conical, beveled, or chamfered recess, depending on its shape. Countersinks come in various sizes and angles, allowing for customization to accommodate different fastener heads.
Countersinking is particularly useful when a smooth, even surface is desired, such as when joining materials together or when countersinking holes for hinges or decorative elements. It enhances the aesthetics of the finished project and prevents potential hazards or obstructions.
To drill a conical depression in wood or metal to receive the head of a screw.

The word "countersink" originated from the Middle English term "countersenk", which was a combination of the words "counter" and "sinking". "Counter" referred to the action of opposing or reversing, while "sinking" referred to the act of creating a cavity or depression in a material. The term was used to describe the process of creating a conical-shaped recess or indentation in a material, often used to accommodate the head of a screw so that it sits flush with or below the surface. Over time, "countersenk" evolved into "countersink", which is the widely-used term today.
