Which tool would you use for creating a recess in wood or metal for a screw head?

The tool designed specifically for creating a recess in wood or metal for a screw head is the countersink. A countersink operates by tapering the hole so that the screw head sits flush with the surface of the material. This is essential in applications where a smooth finish is required, preventing the screw from protruding and potentially causing issues or injuries.

Using a countersink enhances the aesthetics of the finished product and ensures that screws do not catch on surfaces. Unlike a drill press, which is intended for making pilot holes and is not specifically designed to create a tapered recess, a countersink delivers precise and controlled results. While chisels may be used for various cutting and shaping tasks, they are not specialized for creating the conical recess that screw heads require. A router, on the other hand, is a more versatile tool often used for shaping edges or hollowing out areas but is not typically used for the specific purpose of seating screw heads.
